first, you need a regular 98 boot disk
second, you need to download the flash program "aflash.exe" from asus's site
third, you put both the downloaded bios AND the aflash.exe onto a second floppy disk
4th, you boot up off the 98 boot disk, get to a dos prompt, and then put in disk2
5th, you run 'aflash.exe' and back up your existing bios to the floppy
6th, you follow the commands and flash to the new bios (the only quirk here is that you have to put in the *exact" downloaded bios name i.e. a7v1007.awd or whatever it's called)
7th, bios is flashed, you reboot and go into bios and you *MUST* choose "load setup defaults"...then you reboot again and go back into the bios and make any changes you might need to make (because the defaults have been loaded)
and your all set!
i've got the same board, so let me know if you have anymore questions
