You shouldnt be flashing your motherboard BIOS unless you have a problem. If you really want to do it tho...you need to download your motherboards BIOS and a flashing utility from the manufacturers site. Copy the files to an MS-DOS bootable floppy disc. Go to BIOS, set your primary boot device to be the A: drive. Put in the diskette, reboot, and enter the command A:\(flashing utility) (BIOS filename) Obviously replace the stuff in parentheses with the real names. Space between them. For more info, go to the motherboards manufacturer website. You should also note that if anything goes wrong while flashing, you might have to replace or send back your motherboard to the manufacturer to get it re-flashed or else it will not work. It is very risky and should not be done unless you need to fix a problem.
