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

I get an "Access violation" error when I try to download files from Tftpd32 or Tftpd64 running on a Windows Server 2008 R2. The TFTP client is atftp on a computer running Debian Linux. The same atftp command is able to download files from Tftpd32 running on a Windows XP computer on the same network. Does any one here know the cause of this error? A Google search on the topic does not turn up much useful information. Thanks.

Hi everyone!

I've got a problem...

I'm trying to boot puppy lupu (puppy 5.4) from WAN with the following menu entry:

label Puppy
MENU LABEL Puppy Lupu
    kernel /images/lupu/vmlinuz
    append root=http://69ddwrt.no-ip.org/images/lupu/ boot=lupu netboot=nfs nfsroot=http://69ddwrt.no-ip.org/images/lupu/   

    initrd=http://69ddwrt.no-ip.org/images/lupu/initrd.gz

Lupu works fine after booting over http with gpxe firmware but I want to go further...

I want to load the lupusave.2fs file in order to access all the applications I've installed with no need of reinstall all the applications every time I'm booting puppy from pxe.

I've tried with the multiple initrdfile command to load more than one file but it doesn't work...

Any ideas or suggestions?

Any support would be much appreciated...

Regards.

Update
2009-12-12: New version DiskMod v0.0.2.2
See post #23 for more information.

--------

There is an idea from Thai webboard pantip.com.  "Shenzhen Man" asked how to make Windows think external hard disk is internal hard disk, so that it will allow page file to be in the hard disk ?
Normally, Windows creates page file in IDE/SATA/RAID hard disk but not in USB hard disk.  
If Windows creates page file in a partition in internal disk, you cannot format or delete that partition.
If you boot from USB disk and there is no Windows partition available in internal disk, you don't have page file.  
I searched Google and did not find any successful story .
So I tried another approach -- a disk filter driver.  
When Windows tell disk device to prepare itself for paging, the filter driver will return success status even if the lower driver failed.

Here is the experimental 32-bit version.
MF
It has been tested in Windows 7 RC 32-bit only for a few minutes.

How to install this driver (DiskMod v0.0.1.0) in Windows 7 RC 32-bit.
From Windows in USB, open Device Manager.
Find your USB disk device(s).
- When viewed by type, they are in "Disk drives" category.
- When viewed by connection, select child device of USB Mass Storage device.
Right click on disk device and Select Update driver.
Browse My Computer
Let me pick
Have Disk...
Select the directory where you have DiskMod driver extracted to
Select "Disk with pagefile" and click Next
Reboot

Would anyone mind telling me if the "safe INT 0x13 hook" that GRUB4DOS produces is supposed to have its flags set to 1 or to 0? I seem to be getting a 1, but (unless my memory is foggy) I was expecting a 0. If it's too much trouble to ask, I'll try to dig it out of the source code. If it's not too much trouble, then thanks!

Grub4DOS on NTFS Partition ?

Hello

 

Maybe this question has been asked many times but after some twohours googling I didn't find a clea answer.

 

Q1 : Can G4D be installed on a NTFS partition ?

 

I have an external USB 3.0 disk with a single NTFS partition on it (it must be NTFS: FACT; FAT32/exFAT is out of question).

 

Q2: Is it able to boot ISO Images of the NTFS Partition same asa on FAT32 partitions?

 

I use XBOOT to prepare my USB Sticks/Drives but the XBOOT seems to be an orphaned product which is no longer developed.

Therefore I would like to use Grub4DOS directly.

 

Sorry in advance if the information I am asking is written in BIG letters somewhere but I was unable to find it.

 

Regards,

Oliver

@Nuno

the board update has changed AGAIN bbcodes and/or parser (or whatever), and features like image embedding, spoilers, numbered lists are not working anymore or not properly.

 

I perfectly know how this post of mine will be ignored, like all the previous ones about the opportunity of not updating the board "live", but only after having thoroughly tested the new release, and make d@mn sure that an update is actually needed at all.

 

Consequently the only scope of this post is to make sure that  you won't get away with "I didn't noticed" or "noone told me anything about that".

This is probably very simple to fix but I have spent several hours trying to solve my problem but can't.

 

Hope someone can help please. 

 

I have used SARDU to make a multiboot ISO to burn to DVD.  I have added some extra progs to the menu and the final build works fine from QEMU.  However, I wanted to customise the menu for personal easier navigation.  So I extracted all files and folders from the ISO and then updated the isolinux.cfg menu file.  Then I used IMGBURN to re-make the ISO but the ISO isn't bootable either in QEMU of from a DVD.  I understand that in IMGBURN there is an advanced tab in the ISO build mode and under the advanced tab there is an option to make a bootable ISO but I just don't understand if this is what I must use. 

 

There is nothing incorrect with my updated isolinux.cfg file as I have checked that it works by using the same changes with the syslinux.cfg file from a USB build.

Hi!

 

I tried to install it on my pendrive, but I always got the same errors:

 

"Error No configuration file found"

 

"no default or UI configuration directive found"

 

Tried both stable and beta version of SGD, but neither worked. Why wouldn't they work? What should I do?

This thread is reserved for people reporting their success using newish releases of grub4dos that allow for direct booting to a .iso imaging through mappig the ISO image to (hd32).

Ideally, any user who had some success with this way of booting can post here reporting what he succeeded with and how he did it, links to other boards, tutorials guides related to the matter are also welcome.

PLEASE NO request for help here, post them in the grub4dos forum.

PLEASE NO "Nice, thank you!" kind of posts.

PLEASE NO "Ha, this is not useful!" type of comments.

This thread should become simply a list of working setups, no more, no less.

Thanks for cooperation.

Trying to boot Linux Mint with grub4dos, vers. 0.4.5c 2012-11-17:
http://www.mirrorservice.org/sites/www.linuxmint.com/pub/linuxmint.com/stable/12/linuxmint-12-kde-dvd-32bit.iso

Initrd image is in /casper/initrd.lz in this case. The menu is auto generated without checking contents of the ISO, hence the check which initrd image to use.

title Start linuxmint-12-kde-dvd-32bit
set ISO=/ubuntu/linuxmint-12-kde-dvd-32bit_buntu.iso
ls %ISO% > nul || find --set-root --devices=hf %ISO%
map %ISO% (0xff) || map --mem %ISO% (0xff) || map --mem --heads=0 --sectors-per-track=0 %ISO% (0xff)
map --hook
root (0xff)kernel /casper/vmlinuz file=/cdrom/preseed/mint.seed boot=casper iso-scan/filename=%ISO% splash --
ls /casper/initrd.lz > nul && initrd /casper/initrd.lz
ls /casper/initrd.gz > nul && initrd /casper/initrd.gz

This leads to reset on real machine and hang in QEMU right after grub4dos counter for loading initrd image [0/18]...[18/18] finishes.

Removing NUL redirects in last two lines fixes the issue:

ls /casper/initrd.lz && initrd /casper/initrd.lz
ls /casper/initrd.gz && initrd /casper/initrd.gz

I am curious why is this happening?

Playing with another way to boot it:

title Start linuxmint-12-kde-dvd-32bit
set ISO=/ubuntu/linuxmint-12-kde-dvd-32bit_buntu.iso
ls %ISO% > nul || find --set-root --devices=hf %ISO%
map %ISO% (0xff) || map --mem %ISO% (0xff) || map --mem --heads=0 --sectors-per-track=0 %ISO% (0xff)
map --hook
root (0xff)
ls /casper/initrd.lz > nul && set init=/casper/initrd.lz
ls /casper/initrd.gz > nul && set init=/casper/initrd.gz
kernel /casper/vmlinuz file=/cdrom/preseed/mint.seed boot=casper iso-scan/filename=%ISO% splash --
initrd %init%

This works as expected. However, adding

echo TEST > nul

at the bottom of the menu breaks boot again.


Another test:

title Start linuxmint-12-kde-dvd-32bit 
set ISO=/ubuntu/linuxmint-12-kde-dvd-32bit_buntu.iso
ls %ISO% > nul || find --set-root --devices=hf %ISO%
map %ISO% (0xff) || map --mem %ISO% (0xff) || map --mem --heads=0 --sectors-per-track=0 %ISO% (0xff)
map --hook
root (0xff)ls /casper/initrd.lz > nul && set init=/casper/initrd.lz
ls /casper/initrd.gz > nul && set init=/casper/initrd.gz
kernel /casper/vmlinuz file=/cdrom/preseed/mint.seed boot=casper iso-scan/filename=%ISO% splash --
initrd %init%
echo test

- works fine.

Is this expected behavior or a bug?
If it's expected, are there any guidelines what not to use after kernel, or is it after the initrd commands?
Checked grub4dos 0.4.5c 2012-05-16- it behaves the same way.

I have some ideas...

I think I'm an ok programmer who knows a bit about boot processes and Windows stuff.

I will write a computer virus for Windows so that every time the user tries to visit any web-page, they'll be redirected to a new "anti-virus" web-page. The virus will also pop up messages in the system tray that the computer has been infected and if they click the message, it will take them to the same "anti-virus" web-page. The virus will hide all icons on the desktop so the user is annoyed and takes notice that they really do have a virus. The virus will disable the usual counter-measures for troubleshooting such as Task Manager, Process Explorer, cmd.exe.

To flex the BIOS muscles of my brain, I can also write a pre-OS virus which will be a contiguous file that installs for itself a partition entry in the MBR. Every 3 out of 4 boots, it will tell the user they have a virus, then the 4th boot will actually let them boot the OS so they can get to the "anti-virus" web-page.

The Windows virus should probably also let the users access the web-sites of known financial institutions, and it will key-log anything they do there. These logs can be sent to IRC for anonymous collection.

I will take the .ISOs of popular software and re-compile the .ISOs to include these viruses. Then I will distribute the .ISOs via the BitTorrent protocol. Pretty soon, people will re-distribute the .ISOs and the virus will spread just as easily as the greedy people who do not want to pay for software! Well if they don't want to pay for software... They can pay me less money to "fix" their virus!

The "anti-virus" web-page will offer a product for sale or for a monthly fee. When they pay, they install a very simple program that looks very convincingly like a professional product, except that my English isn't that great, so there might be some typos. Hopefully the stupid user doesn't care/notice. The "anti-virus" program will disable the "bad things" that the original virus does, until the user uninstalls the "anti-virus" or stops paying.

Now, here's where you come in!...

If you want to make some money from this, you can help to redistribute the .ISOs! I will give you an .ISO where the virus inside has a code in it. When the user buys the "anti-virus," the program will check for this code and you will make a percentage of the sale if your code was found! Or you can take the custom-code virus and make your own .ISOs and share them with the world!

How many uninformed users do you think would be susceptible to this? If we can make even a one-time $10 for 1,000 people out of 6 billion, that's $10,000!

Do you think this is an original idea?

By default, the virtual drive shows up as a BD-ROM drive on your computer, so even if you don’t have a Blu-ray drive, you kind of do with the ZM-VE200

Just received mine thru the mail.


The ZALMAN ZM-VE200 is based on the licensed design from Iodd.
More detailed review and some great tips[ZM-VE200 megatechnews.com Review]

ZM-VE200 has some great overal improvements from the get go. Well done so far in my testing.

On watching the video on Disassembling the iodd [Video for Disassembling].
you will notice that the person disassembling the device use's a bit of force to open the case. Not so with the ZM-VE200.
I was a bit afraid after watching the iodd video of breaking something.

With Disassembling the ZM-VE200 there is no more struggle to take it apart in order to insert the drive into the case.

To insert youre drive on iodd 2501 was harder as you can see from the picture you had to disassemble it.


With the ZM-VE200 the only thing you do is an easy 4 steps no disassembling . Just beautiful. mmmm! What a relief.
