Greetings,

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.

Cheers,
