DOS with USB driver on CD

[Linux711]

I've always had problems with BIOS update utilities that require DOS because most comps don't have floppy drives anymore, so I end up having to burn a one-time use CD. I put DOS on the CD along with the BIOS firmware, update the BIOS, then throw away the CD. A better option would be to boot it from USB flash drive, but I often find BIOSs that don't support it. Can anyone help me make a preconfigured DOS CD that automatically mounts a flash drive so I can run the utilities? I know I could probably make it work after getting a driver and editing a billion times, but I don't want to use that many CDs. Any ideas?

You could also use a CD-RW...

xboot is a tool available for Windows to create a bootable USB stick.

You can throw a dozen ISO images at it and it will provide a menu to boot from any of them.  Quite neat.


I note that you are concerned about not being able to boot from USB but if your machine handles it then this would be an option. 
I would also recommend a CD-RW though...
