you can repair your bios, but it's very tricky. i've misflashed my bios to the point where i didn't get a command prompt. what you have to do is find someone with the same size bios as you, ie 1 mbit, 2 mbit. and make sure they have the same bios manufacturer as you as well. otherwise it won't work. the bios is only read at startup, and after bootup, it's copied to ram. so here's what you do. download onto a friend's computer a GOOD version of the bios you know works, your old bios should be online on ftp.asus.com. have your friend boot up their computer with a bootable floppy that has the flash software and the bin file for you bios. when you are at a command prompt, remove his bios chip. this will work, i've done it a couple of times. since the his bios is loaded into ram, there is no need for it. now, put your messed bios chip onto his motherboard. you have to be very careful to try to make all the contacts short at the same time, or at least make it close. then run the flash utility program from the floppy disk like you would normally. when the bios flashing program warns you saying "product id mismatch," ignore it and continue. now, MAKE SURE YOUR BIOS IS THE ONE ABOUT TO BE FLASHED. run the program. after it completes, shutdown, restore the bios chips back to their original motherboard. i'll have to warn you, don't do this unless you are damn confident that you can, cuz you can really mess up another bios this way. when you are taking off the bios chip from your friend's computer, you might want to loosen it first before boot up so that the contacts are loose enough where they are making contact but also easy to take out really quickly. hope this helps you out, best of luck to you.
