Go to the gigabyte website. Go to downloads. Go to your motherboard version and then read the instructions on flashing the BIOS. Only do it if you know what your doing (I'm sure you'll be ok).
Yeah you'll probably have to download a BIOS and image a floppy disk to do it. Then you'll probably have to boot from a bootable floppy drive and maybe do some DOS commands. That is, unless they make it mega easy like DFI does!!! :worship:
