how to create cmos checksum error
Posted: Wed Jun 16, 2004 2:44 pm
Hello!
I've accidentaly flashed MVP3 BIOS into VP3. As the boards are similiar, PC booted up but ended POST on memory test without any possibility to enter BIOS setup. I've got two possibilities - hot flash or bootblock recovery. But the only way to start bootblock recovery is the CMOS checksum error, which is possible to happen when shorting chip pins (as the BIOS is OK to bootblock). I've got AT29C010 - which pins should I short to recieve chcecksum error and start bootblock?
