EXACTLY what files do I need to Flash my BIOS?

[JustStarting]

I know I don't need all the files on a standard bootable floppy. I'm running XP Pro, and can't make a bootable floppy to flash with from my computer. I went to drdflash and downloaded that, but the files extracted do not seem right to me- Autoexec.bat, Command.com, Ibmbio.com, Ibmdos.com. Is this everything I need as far as system files (I know I have to add my bios flash to the floppy). I'm pretty sure the .EXE file for my bios flash will install Awdflash.exe alondg with the .rom file. This is for flashing a Shuttle AN35N-Ultra 400. TIA.

Not sure on the exact files you need for the flash, that should be in the manual for the board, but/ if you go to my computer in xp, and have a floppy in a, just right click a and click format, in the options, just click make boot disk... all done.

No instructions in the manual, and the website runs you around in a big loop on making the boot disk to flash in XP.

Yes those look like they will boot DOS. You don't actually need autoexec.bat unless you want to auto-execute some program. The problem will be that the floppy also needs a boot sector that loads ibmbio.com, ibmdos.com and command.com. So you need a program to put the boot sector on the floppy. If they don't provide it, I don't know if you can make it work.

IBM and Microsoft both sold versions of DOS, but they used different names for two of the files that load off the floppy (or HD).Those are the IBM names.

Windows will put a boot sector on a floppy if you format it and choose the option to make a boot floppy. But that loader wants IO.sys (instead of IBMBIO.com) and MSDOS.sys as the files it will load (and also puts those on the floppy.) command.com is named the same. XP puts on a cr*pload of files besides, which aren't needed unless don't use English.

Maybe renaming ibmbio.com to io.sys and ibmdos.com to msdos.sys will work. I never tried it.

Some BIOSes (like the DFI NFII) show you an option to press a key (ALT-F2) when they post, which will load the Award flash program off the floppy and flash a BIOS with the default name, without any DOS files on the floppy, so you don't need a boot floppy.
