Check the following link for hardware and firmware requirements to support Xeon processor 5400 series:
Also, the board requires a SSI 24-pin main power connector, and a SSI 8-pin 12V power connector.
Sorry for the delay in replying. The day job gets in the way
Yes the board powers on. The fans start (just to eliminate that as a potential part of the problem,
I have a fan plugged in on ALL the MB fan ports).
The status light flashes green for about 30 seconds, then goes solid amber. The TSP says:
BW/BIOS: Fatal Alarm. Post error/NMI event
FW Only: CPU/Terminator Missing, Fan, Temparature, Voltage, visible if fatal error causes a power down
The power supply has the the SSI 24 pin main connector, and the SSI 8 pin CPU connector.
What it doesn't have is the power supply "auxiliary signal connector" (I2C monitoring of the power supply).
So I'm assuming again that I have the wrong power supply, or the wrong CPUs. I could buy this:
for $200, but don't have any idea if that would actually solve the problem (e.g. could be the CPUs).
Since I never get anything on the video monitor, I can't check firmware / BIOS versions. I WISH I could get that far
