So I bought this mobo with bad BIOS flash. The owner of the mobo flashed an old F2 BIOS, and not posting anymore. I sorted the 4 and 7 pins on the main BIOS chip, and I got the post screen, but it fails to recover the main BIOS. I tried to use the backup BIOS by sorting the 1 and 6 pins, but not working. Anyone can help me ?
