I was going through the same thing last week. Opus suggests using an AC powered supply to set up the bios. Just got home, haven't solved it yet. I did get the supply to start up by putting in the jumper that changes it from ATX to AT mode, disables handshake. I was using an LCD monitor. There is a bios setting for CRT or LCD monitor, maybe I have to use a CRT to get into the bios; had to buy a PS keyboard because the USB keybord is by defaut turned off. Also, (PD10000 board) I found that, as others have posted, the CLEAR CMOS jumper is factory installed at the CLEAR CMOS position. barf.
