Grub to run batch and exe files

[mirage137]

I've been working on a bootable usb drive with the grub bootloader that basically is a utility to run a number of floppy images, etc. I have a number of submenus created to break down motherboard bios, dmi, download disks and everything works fine. However there is a few bios flashes and utilities that are too big to be floppy emulation images. They originally are on a cd-rom, however with all of there files copied from the cd-rom to a dos bootable usb written with batch files, they work fine.

Basically how can I run batch files with grub commands to run like it's in dos? For example, I want grub to run flash.bat which has a number of dos commands to display a text file of options, and execute the batch files and run the flashes like they would on cd-rom or floppy.

I've been looking all over forums and sites and really haven't seen anything that would seem to help. I hope it's possible and seems like it could, i'm just missing which commands to use and how.

I also looked into running the raw .iso image of the cd-rom but they way i understood reading some forums that grub couldnt' do that yet. I'm running grub .97.

Any ideas? Thanks in advance.

Batch files are executed by the DOS command processor, COMMAND.COM,
which in turn , depends on the DOS kernel. In short, you have to run DOS.

Ok, so for instance in my config file I have:

title TEST
root (hd0,0)
kernel /boot/memdisk
initrd /boot/s5000/dosboot.ima


Where 'dosboot.ima' is an exact image of a ms dos bootable floppy. When I try this, it runs through and bumps back to my main config file. Could I then in my config file just put dos commands then for example:

title TEST
root (hd0,0)
kernel /boot/memdisk
initrd /boot/s5000/dosboot.ima
flash.bat
run.bat

????

when i run this, it still jumps back to my main config file, but when i pause it before it jumps back, the error says "no systemdisk. booting from harddisk".

so i'm assuming i have to put in another command for the dos kernel.
