This site:

http://www.mirrors.org/archived_sof...

says you should be able to use up to dos 5. You can download 5.0 and 3.3 here:

I'm not sure if they'll work on a USB drive but you can try it.

I believe the problem may be the size of the usb flash drive. If it's over 32mb it's probably going to be fat16, this leaves you with a big problem. According to Wikipedia FAT16 support starts with dos 3.3.

The real issue may be making the may be making the drive bootable, I suggest using Hp usb strorage tool(on xp or something) if you don't have a hp drive you have to use the console version of the utility (it will be inside the install directory after installation) and point it to your dos system files.

The site linked by DAVEINCAPS hosts all the DOS versions thru at least 5.0 or later.

When you get the 'invalid system disk' error what drive and OS is it attempting to boot from? Then when you hit a key, what does it boot from then?

And linux is on the hard drive and dos on USB? Usually when you get the 'invalid system disk' and make no changes to the boot devices--such as inserting a bootable floppy--you should get the same error when you hit 'any key' since everything is the same. Unless that's different with your laptop maybe there's a problem with the hard drive. Do you ever get that error when the dos/USB device is not attached?

What parameters are you passing the hp utility? I haven't done it in a little while but I think it should be:

HPUSBF X: -FS:FAT -B:"WHERE\COMMAND.COM\AND\IO.SYS\RESIDE" 

Usually when you get the 'invalid system disk' and make no changes to the boot devices--such as inserting a bootable floppy--you should get the same error when you hit 'any key' since everything is the same.

@DAVEINCAPS

Most newer bios' have a "try next boot device" feature, on boot failure it will display the message "Invalid system disk", hitting a key with out changing media will cause it to try the next in boot sequence(if any).
