I've created a USB boot drive, which I want to use on several computers. The weird thing is that it is being assigned a different drive letter on different computers! For example, the USB drive is assigned the letter A: on my AMD Athlon XP computer, and the letter C: on the Intel Core Duo. This is a problem because I can't have a unified CONFIG.SYS and AUTOEXEC.BAT files for both systems.

The drive was created using HP USB Disk Storage Format Tool, with a Windows 98 boot system.

Any ideas how to resolve this?

Small flash disk ( < 1GB) common problem:
you see a flash disk as 'removable drive' while other as flash disk as 'USB HDD'.
Reason is bios look the size of flash drive to decide wheter it is removable drive or usb hdd
so small capacity flash disks are described as 'removable drive' by bios , and big capacity flash disk are 'USB HDD'.
Solution:
1)
If you have, In usb device section of your bios, change setting from auto to hd.
For example if you use asus p5b
Bios-->Advanced-->USB Configuration-->Legacy USB Support-->USB Mass Storage Device Configuration-->Emulation Type-->Auto
change Auto to Harddisk
ps: "asus p5b" bios is only for help purpose of what you are looking for in bios, if you have diff. motherboard/bios, you should find this in the way it writes in your bios.
2)
If you dont have such an option in your bios (like Asus A7N8X-VM) for now only solution i know is, use bigger (at least 1gb) usb flash disk.


I hope this info helps.

ps: jaclaz, as a master, if sth wrong in my notes please help to fix.

There can be several reasons, besides the one posted. (IMG:../forums/style_emoticons/default/smile.gif)

A workaround should be possible:

Download from here:

Add a 00 byte at the end of the archive:

It should be possible to run in AUTOEXEC.BAT to run a drive letter assignement reading routine, and also "force" it, you'll have to do some experiments:

If not possible directly, use grub4dos and a DOS image:
