Bootable USB Flash memory with DOS

[zero0w]

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 at 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.

I am trying to do this now to accomplish some BIOS upgrades.

Your second link is for a Windows app, your first covers Windows and Linux, but the Linux bit requires a Debian-specific app. It has alternate instructions for other distros, but I have not yet been successful with them.

Does anyone have a nice clear set of instructions that will work under Fedora? After all this is the Fedora forum.

TIA.

I've been able to get my USB pen drive to boot as a USB-ZIP or as a hard drive. What would be real useful is to have grub installed on it and be able to boot to DOS for flashing BIOS, or Fedora kernel with basic utilities for fixing stuff. So far, everything that I've tried to get grub installed has failed. I looked at using loadlin and going that route, but it's just not a clean solution.
