But the problem with that is the tools required to flash a bios typically only work in DOS and therefore will not run in Linux.
For BIOS flashing, I suggest making a simple DOS boot disk or DOS app archive, and add it to the custom menu.
Interesting, found a webpage that seems to have links to programs that run in dos:http://www.opus.co.tt/dave/utils.htm
Anything you have in mind? Most applicable apps there seems to be included already...
Here is an interesting link provided: "Duse v4.9 From Pocketec, are USB DOS drivers for USB hard disks, CDROM drives and other USB storage devices like Zip drives"
Duse V4.9 is already included on the FreeDOS boot disk (select "Config" under the USB menu, and select "Duse driver").
Like I mentioned previously in another post, I have tried all the options but found the USB drivers to be hit-and-miss. I have also tried two other newer-generation DOS USB drivers (suggested by IceCube), and they have similar problems.
I am sure they'd work on some machines with certain config settings, but I want something that will work on most machines without much fiddling.
