Hi everyone , I'm new to posting here, so I hope that I'm posting the right section. I'm actually running a system an opty 144 system with the above said motherboard stable for 2 years. So the otherday I wanted to try out a pair of 2GB RAM modules I bought and I cleared the CMOS by accident while the PC was running. Naturally the system tripped and when I tried to boot up again , it would just hang there and I could access the BIOS. So I concluded that the BIOS chip needed to be reprogrammed via flashing as nothing else seemed wrong with my system. I tried winflashing using an ASUS A8N-SLi Board which uses the same bios chip but I'll just get a CMOS checksum error after reinserting it into the DFI Board, I think due to it being recognized as an ASUS board eventhough it was flashed with the latest DFI BIOS. I read that I could cross flash a motherboard by force flashing under DOS mode (which I tried and failed) . Maybe I just don't know the exact command string or steps to force flash it. Can anyone kindly provide me suggestions / alternatives to buying a replacement bios chip online which costs a bomb ? I've tried local tech forums for anyone kind enough to do a hotflash for me but I have yet to receive a reply. Thanks in advanced to anyone kind enough to help ~!
