Need help choosing RAM upgrade for my gaming laptop

$
0
0
So, I've finally upgraded just about everything except RAM, it's the last on my list. I've already maxxed out my drive slots, I'm happy with 10+TB internal SSD storage (finally ditched my 2 HDDs and relegated them to enclosures).

I've been putting a RAM upgrade off for a long time because it's tricky...I'm worried I'll have to buy each SODIMM stick standalone (will explain below). And I'm not entirely sure what's compatible, what's stable, what will support overclocking (if I want to play around with that).

My main motivation is...well...just having way more than enough RAM than I'd ever need. My current 16GB is enough for modern games, but some games can push 10-12GB RAM usage (the really resource intensive ones, we're not talking DOS games). And besides that, there has to be enough for the OS and softwares running in background, I multitask alot. In short, 16GB is sufficient, but not ideal long term.

I'm looking to move to 64GB, which is the max my mobo supports. Another motivation is RAMdisks (including the OS itself), and caching. I also want to run multiple VMs at once. Doing things like Android ROM building, kernel building, compiling from source code...that stuff is super RAM intensive.

I've opened my laptop, there appear to be 4 RAM slots, 2 of which are occupied (8GB each). One of them has a "GoldKey" sticker on it, and "warranty void if removed". At first I thought it must be the TPM module, but it's too big and rectangle-shaped. Surely my warranty isnt voided by simply swapping RAM? Or maybe they mean void if sticker is removed?

My model:

Sager NP9876/Clevo P870KM1-G (same thing, but mine is Sager-branded, Clevo is the OEM)

From what I can tell, it came stock with 16GB dual channel DDR4 RAM, 2400MHz. So I take this to mean that any upgrade I choose needs to DC, around the same timing frequencies, and obviously DDR4. The frequencies themselves dont need to exact match stock timing/clock config, but it has to be close, or there is the possibility of instability.

Things get a bit uncertain when deciding how many sticks to buy at once. I'm having trouble finding 4x16 kits for notebooks (cant recall any). So far I can only find 2x32. Is it necessary to fill all 4 slots to get 64GB total? It just seems odd to leave 2 slots empty.

Another consideration: If I buy a multi-stick kit, then test them, I have to return the entire kit for exchange/refund if even one stick fails testing. This can become a long, arduous process. I'm not sure if it's better to buy each stick piecemeal, or as a kit.

Final consideration: The sticks have to be "paired", meaning all sticks have to be exactly the same. Or else I wont be able to take advantage of dual channel. Different timings/frequencies/clocks between each could cause issues too. And of course, OCing. Everywhere I've read says not to mix and match.

The brands I'm considering so far are Corsair Vengeance, Mushkin, and Patriot (Corsair preferred, I own a handful of their products, always a good experience so far). Mushkin is cheaper, not sure if there's a quality sacrifice. Patriot's prices are on par with Corsair, not much exp with their stuff. But I know they're vouched for by many. I'm open to other recommendations though.

Thanks!

Hi guys. I need help about filedisk win7.vhd

 

My old pc vin7.vhd and ramdisk was working well but i have changed my pc to HP and it has no options ide achi etc modes in bios all is usb3.0 intel 7 gen.

 

I have created win7.vhd and ramdisk with VHD_W7C_85.exe tools. When i boot win7.vhd im getting bluescreen after loading screen done. i think it needs usb 3.0 drivers when bootup vhd filedisk. i have tried to install usb 3.0 drivers with vm but fails. looked many of docs but didnt work for me.

 

1. Same win7.vhd to Ramdisk works fine but only usb ports doesnt work.

2. Win7.vhd file disk getting bluescreen error after loading screen pass.

 

Can you help me to make my win7.vhd work on new pc with usb 3.0 drivers. Any solition for it?

 

USB flash drive not recognized

I tried to create bootable usb using WinSetupFromUSB but i had to force close it because it stuck on defragmenting. After that the usb is not recognized by windows explorer, i am using Windows 10. Also, it is not recognized by WinSetupFromUSB or Easy2Boot.
The strange thing is that diskpart recognizes the usb and i can successfully format and partition the drive with diskpart. Also, the usb drive is recognized by MiniTool Partition Wizard and i can format it successfully. But the usb drive is still not recognized by WinSetupFromUSB and Easy2Boot. Can this usb drive be repaired?

[bug report] imdisk drive disapears when disk is full

Hey team!

 

I'd like to report another bug I've found on imDisk as it happened a lot of times before.

 

When the ramdisk gets full, 0 bytes left, and programs still try to write data to it, the ramdisk is lost with all data on it. The drive is still shown in the explorer but it becomes inaccessible and the explorer bar that shows how full is the drive is not shown.

 

I've tried to reproduce the error by copying files to it but the bug doesn't happen like that. I guess it happens when softwares try to write to it multiple times when it is zero bytes left. It is not caused by a specific program.

 

Windows 10 x64 8Gb RAM. ramdisk is 1Gb.

 

It might be a Windows issue, I am not sure.

ImDisk Ramdisk use cases

$
0
0

Hey guys!

ImDisk Ramdisk is faster than any other HDD/SSD on the market.

Here are my 4 use cases for it:

 

 

1. Temp folder

 

Placing %temp% folders into a ImDisk Ramdisk not only makes your system faster but also increases the lifespan of your SSD. SSDs wear off with the cycles (I/O). %temp% folder is speacially aggressive on I/O. ImDisk is perfect for that. I also link other folders that are heavy on I/O to R:\

 

 

2. Firefox/Chrome profile folders

 

I also have an ImDisk Ramdisk on Y:\  (256Mb) to hold my browsers' profile folder. For example:

mklink /D "%APPDATA%\Mozilla\Firefox\Profiles" "Y:\Mozilla Firefox"
mklink /D "%USERPROFILE%\AppData\Local\Google\Chrome" "Y:\Google Chrome"

Does the trick.

 

Advantages are:

- SSD spanlife increased. You would be amazed on how much I/O browsers do to your SSD. Thats exhaustive for the SSD and decreases spanlife.

- I have all my browsers profiles in one file dumped to D:\data\profiles.img (SSD) every 1hr.

rawcopy -mldD \\.\Y: "D:\data\profiles.img"

- Browsing speed increased++ :matrix:

 

 

3. IP CAMs (CCTV) video dump

 

Here ImDisk Ramdisk is the perfect buffer.

 

My home IP cams are set to dump videos to an FTP server. Guess where the FTP is... W:\ ImDisk Ramdisk :shifty: .

Faster than any retail HDD meant for CCTV. No DVR on the market can match the storing speed of ImDisk Ramdisk.

I wrote a simple batch script to collect (every 1hr) the dumps from W:\ (freeing space) to a USB pen drive (which is very slow and can't cope with IP cams demand)

 

Advantages:

- No need to spend with expensive DVR / HDD.

- I got all my cams videos in one pen drive.

 

 

4. Loading and playing videos from external HDDs

 

I have a collection of movies on my external 4Tb HDD. We all know external HDD cases can heat up to 48°C easily (specially in my country) with just a few minutes of HDD spinning. That's because HDD cases have no hot air dissipation like CPU cases. (CPU cases are made of metal, which dissipates the heat of HDDs). HDD high temperatures can damage the hardware and compromise the data.

So I wrote a script to allocate an ImDisk Ramdisk to the size of the movie file, then copy the movie to it (which takes about 1min) then start the playback.
 

Advantages:

- HDD temperature is kept low, no HDD spinning noise while watching the movie, energy save.

- The external HDD case can be unplugged since it is no longer being used.

 

 

Intel Nuc and ImDisk Ramdisk is the perfect marriage.

 

So, what else? Where do you guys use ImDisk Ramdisk?

Hi,

 

Is it possible to get what image files are mounted with imdisk?

 

imdisk -l will show only the mounted points but not the image file mounted

\Device\ImDisk0

\Device\ImDisk2

for example, ImDisk2 is an .iso image that was mounted from a batch script. I'd like to get the path to the mounted .iso file.

Install Win10XPE_x64 Flat or Compact Mode on VHD

$
0
0

In this case I used my Win10XPE_x64.iso (builded using as source Win10 18.362.19h1)

 

My Win10XPE_x64.iso size is 811 MB and boot.wim size is 771 MB

 

From Post No. 7

 

From: https://docs.microso...boot-or-non-ram

Quote

 

Windows Preinstallation Environment (Windows PE) is a minimal operating system where you can prepare a PC for installation, deployment, and servicing of Windows. Here's how to download and install it to an internal or external hard drive.

These instructions show how to set up a basic Windows PE installation that runs from the drive. This can sometimes give you better performance than booting from memory, and can help you run Windows PE on PCs or virtual environments with low memory. This procedure is also known as a non-RAMDISK boot, or a flat boot.

Note   When Windows PE is running from the drive, you must turn off the PC before disconnecting the drive to avoid losing your work.

 

Anyway it is not a good idea to think in use a WinPE environment for everyday use, as it is not legal, and can be prosecuted by the law.

 

NOTE-1: this procedure may apply to any WinPE.

 

Requirements:

 

Your Win10XPE_x64.iso, (having all programs booting from Ram) to create it see: https://github.com/ChrisRfr/Win10XPE

 

Procedure to install Win10XPE_x64 Flat and/or Compact LZX Mode on VHD:

1.- Create a fixed or expandable VHD of 3GB or bigger to hold following used sizes, on the root of a partition on your internal HD or USB device (in case of USB device, previously formated with USB_Format_Tool from wimb):

  • Non Compacted Flat install used size of my VHD is: 2.19 GB
  • Compact LZX Flat install used size of my VHD is: 1 GB

2.- VHD has to contain only a single NTFS primary active partition, Inicialized as MBR, MBR has to be 6.x and it is good (but not a requirement) to have BOOTMGR Partition Boot Record, you can verify/modify this with BootIce.

 

3.- Mount your Win10XPE_x64.iso or use 7-zip to extract boot.wim file from the sources folder.

 

4.- By means of wimlib-imagex (from Eric Biggers) or wimlib-clc (GUI by Retokener) make a normal install of the boot.wim to the mounted VHD.

 

EDIT: Also it is possible to install Win10XPE_x64 directly on a Compact mode VHD, using wimlib-clc and the boot.wim file, only required is edit the Wimboot attribute (Flag) of the image. As it already contains its own version of WimBootCompress.ini but we need to apply the Wimboot Flag to the boot.wim first, see post No. 3

 

5.- Mount again your Win10XPE_x64.iso or use 7-zip to extract to the root of the VHD:

  • boot and efi folders, but not the folder sources.
  • and also extract BOOTMGR, bootmgr.efi and bootmgr.exe files but DO NOT extact CDUsb.y XPEStartup.cmd and XPEStartup.ini

6.- Edit or create a new VHD entry in both BCDs located on boot partition of your HD or USB device in accordance with attached pictures External BCD.png and External BCD-2.png, look carefully this is very important:

  • Edit on the Boot\BCD the bootfile pointing to: \windows\system32\boot\winload.exe for MBR/CSM booting.
  • Edit on the EFI\Microsoft\Boot\BCD the bootfile pointing to: \windows\system32\boot\winload.efi for UEFI booting.

 

7.- Reboot and select the new booting option created to test the booting process and the VHD creation.

 

8.- If all went fine, reboot to your current OS or a WinPE, mount the new VHD and capture it by means of wimlib-imagex or wimlib-clc using Wimboot mode as on attached Wimboot mode Capture.png

 

9.- Create a new VHD or mount the one created before and format it to make a Compact LZX install on the VHD.

 

NOTE-2: Same procedure apply also to create a Wimboot mode install. But since the boot.wim boots directly on Ram, this is not a better alternative.

 

NOTE-3: WimBootCompress-WinPE.ini is same as our current WimBootCompress.ini + this added lines under [PrepopulateList]: \Windows\System32\Boot\winload.exe, and \Windows\System32\Boot\winload.efi, but I noticed all the content of \Windows\System32\Boot folder was copied uncompressed, then I need to check if that lines can be optional when using Win10PEs boot.wim, but required on 7 and 8.x WinPEs, in this case they need to also have wofadk.sys installed.

 

EDIT: Confirmed Win10XPE_x64 runs fine with its internal WimbootCompress.ini, no modded version required, see post No. 3 and 5

isohybrid from syslinux and ISO WinXP?

$
0

With the isohybrid tool, you can create a hybrid ISO with Linux that adds a MBR of 512 bytes to the very beginning of the image. I tried to do this with the xp.iso image but the isolinux.bin loader is not there:

isohybrid xp.iso

isohybrid: xp.iso: boot loader does not have an isolinux.bin hybrid signature. Note that isolinux-debug.bin does not support hybrid booting

Is there any way to make a hybrid ISO with xp.iso image so that you can write to a USB flash drive using the dd command?:

dd if=xp.iso of=/dev/sdb

Problem creating bootable usb with Easy2Boot

I downloaded Easy2Boot and created bootable usb using the auto+defaults option. In the end, in the power shell prompt, it showed a line like this: "add alive grub2 file manager..." which i wasn't sure what it means so i just pressed 'Enter'.

Then i copy openSUSE netinstall .iso to the Linux folder, run 'make this drive contiguous' batch script and tested the usb with 'QEMU_MENU_TEST' script and everything went fine without any errors.

But when i boot the usb it shows a black screen with the message: "Missing MBR-Helper". What this error mean?

Grub4dos "isohybrided"

$

Hello,
since I'm already quoted here and have a new feature for this famous forum, I decided to register .
I'm not quite sure, where my ideas fit (Grub4dos ->Grub4dos,.iso images ... or new topic under Grub4dos?) .
I managed to get Grub4dos (0.4.4-2009-11-14) "isohybrided" (comparable to isolinux), i.e. using ONE image for both creating a bootable CD and a bootable USB pendrive. Well, isolinux can do that stuff already ... and it 's faster ! But it can only do it with ONE ISO image on ONE storage device. Grub4dos can potentially do it with MULTIPLE different ISO images on ONE medium. And Grub4dos is able to boot virtually ANY ISO image, no matter if it loads additional files, when running initial ramdisk, since ISO Image works like booted from a CD. At the moment, I have to create such images manually ( of course, I will upload a sample file for your tests and mention my tools), so I search for co-workers to create (Windows and Linux) scripts/programs for process automation, if this forum finds, that it's a useful feature.

The principle structure is as follows :
[ Master Boot Record; Code derived from isolinux, isohybrid]*
[ (fake)1st primary partition; boot, ID 0x83 (Linux; all ISO Image(s))]
[ 2nd partition : primary (FAT) or extended, for GRLDR, menu.lst and else ]


*) grldr.mbr didn't work !

When BIOS boots a USB pendrive as USB-HDD, it gets device (hd0). The Master Boot Record searches for GRLDR, but only on MS filesystems, first primary partition is skipped. So we need GRLDR on another partition, which eases BTW editing menu.lst.

How do we boot first ISO Image ?

menu.lst :

title Boot ISO image 1
map --unhook

# +100024 : size of 1st ISO image in sectors (512B) = 48.84 MiB
map --heads=0 --sectors-per-track=0 (hd0)0+100024 (hd32)
map --hook
root (hd32)
chainloader

StorAhci V1.0 SATA AHCI Controller Driver for Windows 2003 Server SP1 and SP2

$
0
0

Download-Link: https://sourceforge.net/projects/storahci-for-windows-2003/

 

Today we present the new SATA AHCI Controller driver StorAhci version 1.0. StorAhci is based on Microsoft's storahci sample driver for Windows 8 and was changed to support Windows Server 2003 SP1 and SP2 with out of the box storport.sys driver. In addition we added a txtsetup.oem file to load it from a driver floppy disk at the F6 text setup stage. StorAhci is a universal SATA AHCI Controller driver for use with AMD, Intel and any other chipsets.

A special thank goes out to Skulltrail192 for his One-Core-API storahci driver, which was an inspiration for me to port the driver to Windows Server 2003.


How we build the StorAhci driver

We use the source files from the original WDK 8 StorAhci driver sample, which is freely available from Microsoft. The include files are taken from WDK 8 version 8.59.29757. To compile the Windows 2003 compatible driver we use DDK version 7600.16385.1. Our intention was to apply the smallest possible changes to the original code to prevent bugs. We have changed the following things to make the driver work for Windows 2003 Server:

  • added INF and txtsetup.oem file to install the driver
  • added makefile and sources file to compile the driver
  • changed resource file
  • added StorPortPatch header and code file with a few necessary StorPort functions and replaced the function StorPortExtendedFunction
  • changed very important code sections like follows:
  • size of HW_INITIALIZATION_DATA corrected to comply with storport.sys
  • blocked read and write access beyond the end of the structure     PORT_CONFIGURATION_INFORMATION
  • setup physical address for ReadLogExtPageDataPhysicalAddress correctly
  • PREfast and SAL (source code annotation language) changes to make the code compatible with the DDK version 7600.16385.1
  • fixed PREfast and SAL warnings and errors

 

Which operating systems are supported?

StorAhci is build for Windows 2003 Server with Service Pack 1 and Service Pack 2 in both the x86 and the x64 editions. The driver does not work on Windows 2003 Server without Service Pack, because StorPortNotification inside storport.sys does not support the needed notification types. The driver was only tested on Windows 2003 Server with Service Pack 1 and 2, because starting with Windows Vista Microsoft includes a SATA AHCI driver on the installation media.

Well after this very long preamble, let's go to the main subject of the topic.

 

Wonko mentioned several tools on his quoted links, and commented depending of the tool he gets different results.

 

I remembered I have already available SwiftSearch on my PC and decided to give it a try for this task. I have used it before on Wimboot installations to see if a file is a real size file or only a Pointer to the coupled WIM (cero size on disk in this case).

 

Then I created C:\Test.txt file of 700 bytes, and copied it to other partitions on my HD, and also to C: renamed as Test-2.txt, and in all cases the size on disk is 0, wich I take as located on %MFT.

 

Then copied it again as Test-XXXXXXXXXXXXXXXXXX.txt, and just because the name is longer now, it is not located anymore on $MFT, and now same 700 bytes size file is consuming 4 K or 4,096 bytes, a full cluster size, which is the minimum used size a file stored outside of $MFT can be on NTFS.

Getting Windows 95 to install and boot from VHD mapped by GRUB4DOS

$

I'm currently using the latest revision of GRUB4DOS 0.4.6a (2020-08-09) under Virtual PC 2007 and with the usage of the --in-situ command, I've been trying to get original release of Windows 95 to install and boot from VHD.

The size of the VHD is 504 MB (FAT16 formatted), 1,024 cylinders, 16 heads and 63 sectors per track for a total of 1,032,192 sectors. Here is the part of my menu to install and boot Windows 95 in a VHD.

find --set-root /WIN95/BOOT.VHD
map --in-situ --heads-16 --sectors-per-track=63 (hd1,6)/WIN95/BOOT.VHD (hd0)
map --hook
map --harddrives=1
map --floppies=1
root (hd0,0)
chainloader /IO.SYS

When I try to boot from the BOOT.VHD file located on HD1,6 (drive K), I get this output:

Autodetect number-of-heads failed. Use the specified 16
 
Autodetect sectors-per-track failed. Use the specified 63

Error 17:(http//grub4dos.chenall.net/e/17)
         Cannot mount selected partition

I was lucky to set up the VHD using FDISK and format the drive, but I can't seem to proceed any further. I tried to follow this topic, "Can I install Windows 98 to IMG/VHD disk mapped by GRUB4DOS?", but it wasn't too much of a help.

 

Do you have any idea what I'm doing wrong here?

I haven't seen updates in years.  Is this abandoned?  Will you ever update it to support modern booting via EFI?  Are you willing to share the code so some of us, myself included, can update it to support EFI and make this work again?

LockDismount v0.3.0.0 [Update]

$
0

Hello Community :cheers:

LockDismount is a small tool that does only one thing (or two to be exactly). It locks and dismounts every volume of a physical drive (HD or UFD for example). That's it!

So what is that good for?

Microsoft changed the way programs can directly write to physical drives in Windows Vista and later.
More technical background informations about this new 'feature' (or restriction) can be found here: http://msdn.microsof...y/ff551353.aspx

Unfortunately some older (but still good and useful) programs are not compatible with this new restriction and stopped working. You will usually see an "Access Denied" error message when they try to write to .PhysicalDriveX.

This is where LockDismount can help. By locking and dismounting all volumes it will allow some of these older programs to work again.

How to use it?

Posted Image

It's simple. Select the Drive you want to lock and press 'Lock it!'. Now open the 'older program' and let it perform the task that usually gave you the access denied error message. When done, unlock the drive again. That's all.
The only important thing is that every volumes gets successfully locked and that you keep them locked until the other program is done.

Please note that you can not lock your system drive or any drive that holds a pagefile!

The idea for this little tool was born here:
http://www.boot-land.net/forums/index.php?...st&p=108122 by Wonko ;)
So you know who you have to blame for it :ph34r:

How to use the Command Line Interface?
LockDismount will open in GUI mode if you start it without any command line parameters. If one or more parameters are given, it starts in CLI mode.

Posted Image

Batch script example (including Wonko's modifications):

@ECHO OFF

lockdismount -lock 4 someapp.exe -someaction .PhysicalDrive4



IF %ERRORLEVEL% EQU 0 ECHO Operation succeeded!&GOTO :EOF



IF ERRORLEVEL 999 GOTO :NODRV

IF ERRORLEVEL 998 GOTO :LOCKFAIL

IF ERRORLEVEL 997 GOTO :EXECFAIL

IF NOT ERRORLEVEL 0 GOTO :CMDFAIL

GOTO :EOF



:NODRV

echo Drive #4 doesn't exist!

GOTO :EOF



:LOCKFAIL

ECHO Failed to lock/dismount volumes!

GOTO :EOF



:EXECFAIL

ECHO Failed to execute external command!

GOTO :EOF

Assumption:
You have two different Operating Systems (Windows).
One of them is booting well - the other does not (maybe BlueScreen).
You suspect a missing or incorrect configured boot driver service.

Use BootConfigComperator to compare these startup configurations.

- Make shure you can access the non-booting Windows system.
- Start BootConfigComperator as Administrator. (Win8 and beyond)
Reference 'CurrentControlSet' of your booting system is set to first Input.
- Select [Edit]-[Offline Windows]
- Navigate and select 'Offline Windows' directory.
Active 'ControlSet000n' of remote Windows system is set to second Input.
- Click [Read/Compare/Edit] to see values-table. Look for 'Diverse=1'.
- Select mis-configured boot driver (if any) from the table and press [Run User Func].
- Set new valuename (REG-DWORD) to match correct one.
- Click [OK] to write to Registry.
- Click [Cancel] to open Registry and edit manually.

If any mis-configured driver was the reason for non booting system your problem might be fixed.

Special Features:
- to filter the 'usual suspects' e.g. disk drivers, provide a file with a list,
name it BootConfigComperator.ini to be auto-recognized by the program at start.
- there is a chance to install a sample file [Help]-[Install Config Sample].
- use any config-file of this kind as parameter, e.g. 'BootConfigComperator.exe B:\myConfig.ini'.
- if filter is loaded, it is indicated in the GUI.
- use [Help]-[Debug Mode] to display error messages when loading offline Registry fails.
- to edit 'CurrentControlSet' leave empty second Input.


Hope this helps to get some non booting system started.

Regards T.

How to reset a Windows 10 installation on an external hard drive?

$
0

I'm typing this from my laptop, while booted in using an external hard drive. I wanted to make a fresh windows install on the external hard drive, and after trying a bunch of stuff that didn't work I eventually got it to be bootable by using MiniTool Partition Wizard to clone my entire laptop's drive (partitions, system files, personal files, everything) to the external hard drive. I thought I would be able to reset the windows installation on the hard drive from there, using the Reset this PC > Remove Everything feature. But when I try that, it says: "Your PC can't be reset because it's running Windows To Go"... I want to reset the newly cloned installation on the external hard drive, not the one in my laptop. I can't find any information or tutorials on how to do this. Does someone know how (or have an idea for a better method)?

Download: https://drive.google.com/file/d/1liz64jrvmXefWn-Fvo_PLu1LdE2f6xXC

 

GRUB4DOS now adds experimental UEFI support (by @yaya2007).
 
The following features are currently supported in the UEFI version.
1. Boot ISO and IMG files. ('map' command)
2. Boot EFI files.
3. Built-in hotkey support.
4. You can use ‘graphicsmode’ command to see which graphics modes are supported by the UEFI firmware.
5. TFTP PXE boot.
Most other commands are not supported.
 
Example menu:
timeout 5
default 0
graphicsmode -1 800

command line: one-liner to copy specific files to more than one destination?

$
0
0

Dos a one-liner command  exist to copy a file to several directories, preferrably as part of a windows shell script? No external tools (such as robocopy) must be used.

The copy command allows use of  different source files but one destination directory only.

Is there any possibility (or maybe a command line quirk) to overcome this restriction?

Or maybe a better command I should use?

Environment: WinXP, Win7 or Win10.

 

Scenario:

A file list (.txt file) that contains hundreds of file names and their destination folders.

Something like this (snip):

"*genotypisierung*.sav"   "Folder1"

"*_strahlentherap*.sav"   "Folder2"
"*tumorkonf*.sav"            "Folder3\Subfolder1"
"*tumorkonf*.sav"            "Folder3\Subfolder2"

...

 

This was my first approach to walk through this list (destination folders has been created before via MD command):

FOR /F "tokens=1-2 delims=[space] [tab][space]" %%a in ('TYPE "FileList.txt"') DO (
COPY /N /Y %%a %%b >NUL 2>&1 || ECHO.  Error copying  %%~a to %%b && SET _Err=1)

Have a look at example entries 3 and 4: It's quite annoying for me to repeat the folder names for one specific file if it has to be copied to different places.

 

Any suggestions to improve this approach?

 

 

Much thanks in advance for any response

If attached drive has NO letter assigned, how does Window calculate the GUID (highlighted)?
 
The last part is obviously MAC address of the VM, but the rest?
 
The Data column is not an issue, as it is explained well here or here
Also it is NOT the same value as displayed from mountvol (ofcourse not, disk vs volume)
Volume GUID is explained here on page 182 of

Hi everyone,

                   Can anyone recommend a free tool that is able to mount an external USB drive that windows reports as being unformatted/raw to view and fully recover the folder structure and files.  Ideally it would be possible to run it in a WInPE.

 

Thanks in advance.

Exploit vulnerable drivers

$
0
0

Hi Gents,

 

On my spare time, I took a look at unsecured drivers in the wild.

There is a long list of vulnerable drivers (specially coming from motherboard manucfacturers).

 

What is a vulnerable driver? A driver that will accept IOCTL's from anyone (rather than only a specific application).

What can you achieve? Modify memory in kernel land.

 

Therefore I gave it a go with rtcore driver (from MSI) and decided to play with the EPROCESS structure.

Quoting MS : "The EPROCESS structure is an opaque structure that serves as the process object for a process."

And there are a lot of goodies in this "opaque" structure - starting with the PPL flag ("protected process light").

 

Quoting Kapersky : "Protected Process Light (PPL) technology is used for controlling and protecting running processes and protecting them from infection by malicious code and the potentially harmful effects of other processes."

 

So there are times where you would like to shutdown a process or access or its virtual memory ... and you just cant.

 

Changing the flag of the process in its eprocess structure will make it possible.

 

The sourcecode and binaries are there.

 

Be (really and very) careful as you are playing with kernel there (and you should not) : BSOD's are right there at the next corner.

 

Syntax:

memRW.exe load "%cd%\rtcore64.sys"

memRW.exe list
memRW.exe removeppl PID
memRW.exe makesystem PID
memRW.exe stealtoken from_pid to_pid
memRW.exe unload "%cd%\rtcore64.sys"

 

In the future, I aim at reading/dumping memory right from the physical memory rather than from the virtual memory.

 

Comments, feedback, etc welcome.

 

Regards,

Erwan


Grubutil FAT reports wrong 'free space' on FAT32 drive

$
0
0

While testing a script which is build around 'FAT', one of Chenall's Grubutils, I did some copying with bigger files and I ran into problems.

 

While copying a 1GB test-file to a 40GB FAT32 drive, 'FAT' gave me following:

 

'Need more space: 802336 KB,Current available drive space: 246240 KB

FAT Error (7): Access denied due to prohibited access or directory full'

 

This was strange, because the disk had still plenty of free space, about 37GB.

 

Also the size of the test-file was not the problem, just before I copied a 1GB file from a FAT16 drive to the same 40 GB FAT 32 drive. Using 'FAT copy' standalone gave the same error. :(

 

FAT info (hd0,0) gave the same free space, but also a strange result:

 

Fat sub-type: FAT32

Sectors per cluster: 64

Sectors per FAT: 10238

Number of free clusters: 1187343

Total Clusters: 1310231

41927392 Total drive space.

246240 KB available

 

Everything matched with the CHKDSK-report in MS-DOS afterwards, except of course the free space, which should be 37994976 KB according to CHKDSK. This is exactly the same calculated from FAT info above: Number of free clusters * Sectors per cluster * 512 bytes per sector / 1024 = REAL KB available.

 

To be sure I tested latest version of FAT too: found in g4dext-2019-07-14.zip on https://github.com/grub4dos/grubutils/releases but no difference.

 

I tested FAT first in VBOX 6.0.18 r136238 (Qt5.6.2) on VHD's, which gave report above.

 

Later 'in the wild' on a 30GB SATA hard-drive. On the SATA hard-drive I could copy three files of 1GB-size without problems, the fourth 1GB-file gave Error (7). At that time the free size was 16,2 GB. 'FAT info' reported 209520 KB available, and 1061671 free clusters of 32 sectors per cluster. After a full reboot the error remained. :wacko:

 

I don't know how to upload print-screens on this forum, so to be sure here's the output inserted as code, I made with help of GRAB.G4B (but cleaned from the annoying spacing between each line of output).

 

First one inside VBOX with my script FATCOPY.G4B:

Hi @ll.
 
Antecipated excuses if what I'm about to post is poorly worded, has already been answered or is in any other way inappropriate for the forum.
 
My question is simple: is there a known recipe to make any Linux flavor boot up from a VHD virtual disk image file?
 
Some context for this query has already been posted to UbuntuForums, but unfortunately the thread was closed before it got any relevant answers.

Notwithstanding, I just found a personal message containing encouraging info which I'll just transcribe here:

Hi, Everyone.

KLOOP is a new method to boot UBUNTU (Fedora, ARCH, OpenSuse, Mageia) from fixed img and fixed vhd.

It is based on the command 'kpartx' and using loop device as /, so I named it KLOOP (Kpartx+LOOP).
 
If you want to try it, click on the following :
http://pan.baidu.com/s/1bnnjBXX

download and decompress the file 'mydracut-English.zip', and read the file 'mydracut/ubuntu-kloop/readme-KLOOP-UBUNTU.txt' or 'mydracut/fedora-kloop/readme-KLOOP-FEDORA.txt'.[/font]

 
Sadly, the Baidu link doesn't have the English zip file available for download anymore, only a 'mydracut.zip' with Chinese instructions too complex for my extremely limited linguistic and computational capabilities; so I decided to post it here, where it is bound to at least stir some interest, in order to avoid a possible good solution going to waste....
 
Any help, info and/or links highly appreciated.

Nano tools

JFC it's been a LONG time. I haven't been here since 911CD and Bootland. The only familiar names showing up are toolkit authors in the Downloads page. If you guys are still around, it's great to be back. I've been getting by over the years with very little frustration thanks to the memories and struggles we all carried with deep interest in WinPE from the crude nu2 era. Last week I was looking up tools from some familiar names (TheTruth, Paraglider, Misty) to update some libraries and was pleasantly surprised to find some sites still up but realized that it's probably not enough. I may once again need help figuring out a new project and remembered this place exists. While I'm proud of you all and Reboot.Pro is a godsend for those of us that actually make any attempts to understand WTF is going on, I'm fairly certain none of us are ready for this headache, namely because I'm not even sure if it's appropriate to my goals and I appear to be the only one talking about it in any friend group.

 

The tiny pink elephant in the room is Windows Nano Server.

Nano Server Quick Start | Microsoft Docs

 

 

For context, I've done very few hardware changes over the years but my server situations have remained relatively the same with lots of unusual scaling and more competent hardware with apps that eat several GB of memory instead of MB. One of the biggest things that made me stop and reevaluate full WS installations was discovering the serious driver and memory overhead involved in some apps on newer systems. I can get rid of these or try to do better. The discrepancies range from mild to wild depending on the core flavor, priority channel and install type of the OS. For the past 3 years I've switched all production over to Windows Server 2012 R2 for myself and recommended it to all my clients. I'm at a point where it's probably time to move on from this but WS2012R2 is the most efficient and compatible balance that I've discovered shy of making the system completely headless. Nano Server looks ideal for what I want but this is where things get really stupid:

 

Nano Server and Containerization: Build Docker Windows Container (acodez.in)

 

Microsoft made two primary builds of Windows Server 2016 since a few Tech Preview builds. My R1 candidate included a build path for Nano Server as a very self-involved option for situations where both the full desktop experience and server core deployments are too much overhead. So this purely headless option was made and later prioritized to handle Hyper-V and Docker/Containers, which I personally avoid. The above article does a great job outlining how and why that doesn't work out of the box. At this point the 2016 distribution has been memory holed by Windows Server 2019 and this new VM+container direction. While I personally enjoy the extensive driver compatibility and application support in WS2019, there are too many bugs and app issues that make it less than ideal for prime time, let alone for building something like Nano Server. It's fun to play with but a nightmare when you need to get any real actual work done, so I'm probably about to start looking for my first consumer level OS in 15 years. There appears to be a NanoServer distribution for WS2019 but it's not included in the install media or the evaluation image. Instead, you pull it through Powershell and Docker then mount it to Hyper-V. You don't "apply" it to a physical partition like the 2016 model. The 2019 model is only available for use inside a VM, which I've learned doesn't play well with VMWare. Since my test tools only ever involved Qemu and VMware, I resort to grabbing a 64-bit copy of WinImage that allows for VHD/VHDX conversion and convert the file to VMDK before loading it into VMware.

 

Whether you use the Windows ADK for Windows 10 and Nano Server Image Builder to build a Nano Server VHD/VHDX or build everything through a few minimalist Powershell scripts, you essentially end up with the same product by taking the WIM image file, adding packages and converting it to VHD/VHDX for deployment. All the network and related drivers need to be added during compilation so if you don't have all the necessary 64-bit drivers it can be a hassle to get this working right on the first few tries. I would recommend testing in a VM as the WinPE script for deploying Nano Server is extremely destructive to any physical system. I would prefer to detach any physical disk from the system before deployment and possibly installing it directly to a DOM if possible, allowing for simple tests.

 

Both the factory WIM and deployment-ready converted images appear to have the same post-processing abilities as any other WinPE so I'm really curious if Nano Server can be prepared and deployed similar to the ways we use WinBuilder or PEBakery. Seeing how we're all on 64-bit systems and Nano Server has most SysWOW64 libraries stripped out, it would be interesting to bring some relatively minimal 32-bit support and setup some custom background services to run a truly headless server. Without any sort of local logon or GUI, this will force me to think of my own server situations and deployments in significantly better ways. In the 4 years that Nano Server has been around, it hasn't had any real traction. Nobody is talking about it and it's probably time for another look. I've physically installed this to an older system twice and that was as soon as WS2016 went retail. It has a bit of a learning curve when all the management is remote Powershell/WinRM but I think it would be better practice for me to be using this on my minimalist .NET+SQLEspress web+NAS+video stream/ingestion system than giving it a full Windows UI. I recognize NIC teaming is going to be a challenge to do what I want but if I have to login via remote desktop to run huge network, power management and studio apps that should be background services with a web UI, or a management panel on another computer, I would prefer to be on those instead of resorting to remote desktop, especially now that most management situations are mobile and allow for quick maintenance. Would you guys consider this to be a reasonable situation or is the concept of a headless Windows Server just that? I personally think it's really close and just needs a little bit of work. Thanks.

M5StickC, cheap complete mini-computer for prototype

Hello,

 

Most recently I've been passing my time with small embedded devices and electronics. One of the devices that surprised me positively has been the M5StickC: https://m5stack.com/collections/m5-core/products/m5stickc-plus-esp32-pico-mini-iot-development-kit

 

This is a tiny device that comes with:

  • WIFI
  • bluetooth
  • dual-core CPU at 240MHz
  • microphone
  • color display (for text and graphics)
  • Infrared LED

 

The price is 14 USD.

 

It is not strong enough to run a full blown operating system like Linux or Windows. However, comes with a nice web interface for drag&dropping the actions you would like it to do.

 

I've got two of these devices since months and find them really great for prototyping without much fuss.

[bug] imdisk allows mounting a disk on existing C:

Hey guys,

 

I was testing imdisk here and by mistake I set the mount point to C: where Windows and all programs are installed:

imdisk -a -s 1073741824 -m C: -o rem -p /fs:exFAT /q /y

For my surprise it DID WORK! The system root was gone! I had to reset the PC because nothing else was working! My C:\ became an empty ram drive :blink:

 

After reset everything was back to normal

 

Shouldn't imdisk check if the drive letter is in use or something?

Is it possible to use grub4dos (installed to MBR) with modern motherboards?

$

My relatives PC failed. The PC had a hard disk with g4d installed to the MBR. Three primary and a few logical partitions. He got a new processor + mobo.

With a Intel G6400 processor and Gigabyte GA H410M H motherboard, I'm not able to boot from the hard disk.
I have a UFD with grub4dos installed to the MBR, and that won't boot too.
In both cases after the PC boots, there is a blank screen.

I have enabled CSM.

I remember the previous mobo BIOS had a option "Boot Mode Selection" which was set to "Legacy only". This option does not exist for the new mobo.

I would like to use g4d, what BIOS settings should I enable ?

See screenshots attached. First one is from the mobo manual.

(Toshiba transmap ... is the UFD, btw)

Install VirtualBox into Winpe "in live" and get it after the reboot of Winpe

$

Hi,

First, sorry for my poor english.

 

I am the man who does a lot of useless things. The one I am describing here is certainly useless. But I have to spend my free time.

 

I built a winpe. i put it in a VHD. i copy the VHD in a Usb disk. I plug this usb disk to a physical computer. i boot into Winpe. I download virtualbox ( with Edge because it is present in winpe). I launch the installer program of virtualbox : No error. I launch virtualBox program. I create a VM. I attach an old VHD to this vm. I boot this VM : OK. I stop this VM.

Now, if a shutdown winpe and i reboot : i lost virtualbox.

 

To keep VirtualBox, 2 possibilities :

1- identify drivers and add them in boot.wim : i don't try this and don't if it works really

2 - save the 2 hives, system and software, change SetupInProgress ans SetupType. And copy the saved files in ...\config

 

Yes, one big limit : i can't boot on a very different physical computer.

So, useless.

And Yes, I know, it's better to use Linux.

 

Nevermain, i 'm happy to verify that i'm not too old and i can get a positive result in this day, not a BSOD.

 

To access the MS Symbol Server from Winpe's "System" session

$

Hi,

First, sorry for my poor english.

Perhaps useless, as many thing i do.

 

When I encounter an anomaly in Winpe, I often use Procmon or Windbg.
But in the System session, I can't access the MS symbols server directly
So, I used the cache but it required me to collect the symbols beforehand from the session "ADM" to fill the cache.

 

The 20h2 version doesn't bring any great new features other than edge (about 300/400Mb!).
Also, to keep my mind busy in these times of Covid19, I did some research and testing on this subject.
Since I don't think anyone's research is interested, I give the result directly.

 

I use symchk.exe for demonstration here because it's faster.
The environment variable allows you to create the log file for Dbghelp.

 

The solution is to change a single key.I wish I'd known her before today.

 

Here's the result:

 

 

 

X:\windows\system32>set DBGHELP_LOG=\DBGHELP.LOG

X:\windows\system32>X:\Debugger\symchk.exe x:\debugger\symchk.exe /s srv*https://msdl.microsoft.com/download/symbols
SYMCHK: symchk.exe           FAILED  - SymChk.pdb mismatched or not found

SYMCHK: FAILED files = 1
SYMCHK: PASSED + IGNORED files = 0

X:\windows\system32>reg add "hklm\SOFTWARE\Microsoft\Symbol Server"  /v NoInternetProxy /t REG_DWORD /d 1
 

X:\windows\system32>X:\Debugger\symchk.exe x:\debugger\symchk.exe /s srv*https://msdl.microsoft.com/download/symbols

SYMCHK: FAILED files = 0
SYMCHK: PASSED + IGNORED files = 1

The log file confirms access after the key has been changed.

No BSOD, i'm happy.
 

problem reading GPT external drive (using windows 7 32bits)

$

Hello,

I'm trying to read a toshiba sata/usb external storage drive (500GB/465GiB). A friend told me he can't read it anymore and that there is some photos on it. Don't know what happened.

I'm using bios/windows 7 32bits computer and for what I can see using testdisk and photorec, disk is empty but formatted in GPT and there is a first 'microsoft reserved' partition of 16.5 MB (not 32?); indeed I can't read it but maybe there is some trouble with it since I get 'bad sector count' error message or 'can't open for reading' with gdisk and 'unallocated' in windows disk management.

Here are some tests I made so far, let me know if you need anything else:
(hd0 or /sda is my current windows, hd1 or /sdb is the problematic usb drive)

- tinyhexer log and MBR/PBR/GPT backup can be found in the attached file (link at the end of the msg)

- drive doesn't show up in windows explorer but appears in device manager and as shown in the screenshot disk management shows unalocated drive space. Didn't try 'set new volume' and assign letter to not wipe out any content but the option is not greyed out (hence, can't try chkdsk for now - but don't know if it will be of any help here, gpt drive pluged in bios/mbr system)

- testdisk finds an efi/gpt drive but with 'bad sector count' error; tried different geometry (num of sectors per head 255, 240, 16, 32, 128), no change
  also tried intel/pc (mbr) or mac, same

- ran photorec all night long then easeUS data recovery wizard, didn't find anything

- used 'Toshiba Storage Diagnostic Tool_1.30.8920', it says disk passes the tests and is healthy (chs is effectively 60801 255 63 / 512)

- booted a linux system rescue iso with gparted, it finds the two partitions but can't read them, even that 'microsoft reserved partition'

- used dmde-3.6.0.770:
  first message is something like 'volume is probably not fully accessible' but initial and available space mentioned are the same (976 773 168 LBA x 512 (500 GB))

  didn't try 'gpt off' without your advice
 
  ntfs and mft modes just shows 0 everywhere from lba 3 to 976 773 163 (nothing after, shouldn't it be  976 773 168?)

  I put some screens of the first 3 and the last bloc, everything in between seems to be 0 everywhere, but I don't know if the drive is read correctly.
 
  performing full scan: will end tomorrow!

What I'm wondering firstly is wether I'm supposed to be able to read a GPT drive or not (a priori win7 x86 should have driver for it) and then what can I do except clean the disk and convert to mbr? (unless it is actually empty) It seems like someone/something ;) formatted the drive in GPT type

(unfortunately I don't have an efi/gpt computer with windows x64 to test further)

Attention: server transfer (2021)

$

Hello,

 

The forum and whole server is being transferred to a new machine. In theory this should solve the difficulties with the database and get new stability in overall.

 

There is no definitive time line for completing the operation. First the forum will be moved, then will be moved the other related subdomains.

 

My apologies for the downtime or any replies lost in the meanwhile. Hopefully this should be fast to complete. Please do post feedback as you see necessary, especially about broken links to other related sites as they are a bit more difficult to move around.

 

btw: As good news, it should be possible to bring back the 911CD forum in read-only mode. Fingers crossed.  ^_^

 

Many thanks.

 

:cheers:
