A couple of questions about the system:

How much memory does it have?
Is that amount shown on the console?
Did you try to reseat each pci board and memory module ?

My initial message was misleading in the sense that I did not mention
that most of the time, the fans turn on but the front panel LCD does
not. This means that there is no diagnostic. Moreover, I only get
output to the monitor *if* the front panel has already given some sign
of life. Then, when it finally gets as far as output to the monitor,
everything goes black after a minute or two whilst the fans continue
to turn. Maybe this suggests that there is some poor contact
somewhere or a bad power supply perhaps?

The configuration is fairly straight forward:

pbxga-aa/an video card

0x 0 MB bank 3
4x 32 MB bank 2
4x 8 MB bank 1
4x 256 MB bank 0
ECC bank not present on this motherboard

The memory appears to be recognized (when I can get that far in the
boot console). There is one slot in bank 1 that has visibly suffered
some abuse but with some play, one manages to insert the SIMM.
Reseating the SIMMs has not helped.

Right now I'm taking apart the machine piece by piece. I've turned it
on without the RAM and the CPU daughterboard. Still no output to the
front panel LCD. Perhaps I'm just making things worse!
