Will DOS be able to load USB devices? I thought this only worked when I
booted off the device using some BIOS magic.

This requires Windows, I think.

Bah! I'd rather not buy new hardware just for this one predicament.


This is what I have readily available:

 - Computer running FreeBSD
 - USB CDRW-drive
 - 512 MiB USB flash drive
 - A 1.44 MiB FreeDOS floppy image with 111 kiB free space
 - A FreeDOS iso9660 image
 - A 784 kiB DOS executable for flashing my BIOS


Using these I need to make some sort of bootable DOS device (either CD
or USB flash drive) that contains the above mentioned BIOS upgrade utility.

Could I either:

 - Get the BIOS utility onto the ISO file without braking the boot code
 - Use the floppy image to make a bootable USB disk somehow?
