This isn't a new topic. Already there are many guides out there for creating Bootable KNOPPIX on USB Flash card or memory stick. Here, I am looking for a different but also important problem: getting DOS (Dr. DOS / OpenDOS / FreeDOS, etc.) to boot on USB Flash memory.

This will be useful for flashing motherboard BIOS (or display card BIOS). Also many recent notebook models just don't bundle floppy drive anymore; Nor do I have any reason for owning floppy disks if I can have DOS bootable on USB memory card, and flash BIOS with it.

Here are the guides for creating bootable DOS on USB memory stick or Flash card.

what can I say, apart from "whoa! just what I need!". At the mo I'm doing a rewrite of a very, very old application that was based upon DOS 6.22 and EMM386.EXE (THE HORROR!

So a million thanks to you, dude/dudette (dunno), as this will greatly aid me in my "time-travelling" task, back to the shores of "himem.sys" and "smartdrv" as the techniques described should give me a "DOS"-box quickly on any of the dev-machines via the USB-devices, thanx!

(I'm already curious what the DOS network layer has to say to the on-board gigabit-NICs, tee-hee)

No problem, don't mention it.

Can't believe DOS developers are still around. 8)

Nice find!

I've been strugging with my bios and pen drives and this may help a lot.

Sometimes the need of the few outweigh the needs of the many. And...(signature)
