Hi,
It is fairly easy actually. I do it this way:
Set the bios to configure the USB device as a large floppy or zip drive.
With the usb device in, boot from a bootable DOS system floppy and then
do a 'sys b:' or a 'format b: /s'.
Note: The bios will assign the floppy usb device as drive b: when there
is a physical floppy already in the
system unless you boot from the usb device directly.
Now you can boot the floppy usb device or take en image of it (eg: dd
if=/dev/sda of=floppy-usb.bin) and
use it together with memdisk.
I hope this helps you.
