Hey guys, first post here. I have a computer here that has a "BIOS Rom Checksum Error" upon boot up. The computer doesn't post, and I can't get in the bios. It does nothing but give me a black screen with that error, and then the following line occasionally says Detecting IDE Atapi Device. I have read around, and think I need a new bios, since the old one got cleared or corrupted in a CMOS Clr. My question is, how do I flash a new bios without windows, or through the old bios. I have tried using drdflash to make a boot disk with AWDFlash and my new bios version on it. I have an external floppy plugged in through USB that didn't seem to do anything. I also tried an old floppy I had lying around that I plugged into the IDE that didn't seem to do anything. Did I do the boot disk wrong? Is that not my problem? Am I going about it completely wrong? It's an Asus Striker motherboard, Q6600 Chip, running Windows...if any of that helps. Thanks guys, I look forward to your replies.
