Greetings,

Original message:

This machine was working fine before I powered it down and moved it to a new
facility. Once in the new building, the first test of iod_script fails for both
IOD0 and IOD1. Thus, the system will not boot. I dropped into diag mode to run
iod_script manually and see the output. Here's an image of the output of test 1
on both bridges:

A friend saw what looked like corrosion on these two chips, so he scraped a bit
off with a push pin and we're still seeing the same behavior. I've removed the
CPU risers, memory risers, and all PCI cards, reinstalled, and still the same
behavior. Is this board damaged? If so, anyone have a spare? ;) If there's
anything I can do to fix this situation, please let me know.

Martin Andersen suggested also checking if the memory modules and other chips
were seated properly. I found the TOY chip to be a little loose, but this did
not fix the problem. Reseating the memory modules fixed the problem.

Thanks to Martin for encouraging me to rock the boat a little more.
