Some motherboard companies will replace your bios for you at a cost, I think.
There's a dangerous way to fix a bios too, without sending it to the company. If you have a friend who has the same board as you, you could take his bios chip out and put it on your motherboard, boot up, get ready to flash bios, and then take out your friends chip and put yours in. Flash. I've heard that this works but is very dangerous. I certainly wouldn't try it.
