I think you need to make a bootable disk with a BIOS
rom (from Epox site), the awdflash software and probably an autoexec.bat file "calling" the awdflash with the correct options.
But someone else will probably be able to explain this better then me, I've never done it

. (Never corrupted award bios).
Maybe you can find some info @
www.epox.org (Epox UK website).
