The board arrived today (Monday). Looks great. I installed back almost everything. Next step on Wednesday. I hope I will have the time to power it up. I'll keep you informed.
Thanks again.

Hi Blacksmith,
Thanks for letting me know you got the board safely.
You saw that I put a lot into packing that and at this juncture I am thinking about trying to find dedicated packaging for fuel boards to sort of permanently solve that aspect of the repair.
But good to hear it arrived and everything looks to be intact. I did not remove any of your RTCs/batteries so all your settings should be there but I would highly advise you to connect to your internal L1 serial header and monitor it during this start up for obvious reasons. As we've discussed you had a lot of different error messages and I'm still a little bit concerned about your PIMM 12V low voltage alert message because that will not be affected by anything I repaired. As the PIMM has its own DS1780 IC on it.
So I'd like to advise that you take it slow and watch your L1 first and verify your environmental monitoring and voltages look good and run the tests I advised on the expansion I/O and I2c buses (from L1). Check fan RPMs and temps as your NODE0 temperature reading was definitely bad before. The chips I replaced should control the listed NODE0, NODE1 and BEDROCK nodes. The PIMM and XIO sensor value ICs are mounted speartely on their respective boards/cards.
Only afterwards would I say to use the power up command. Also make sure to keep copies of the L1 log, especially if you end up resetting everything as a troubleshooting method.
I certainly hope everything resolves for you, But if you still have a few of the errors you posted before. I advise you to update the thread you had going for your initial problems, and we can continue to weed out anything left.
Also, to summarize my advice on your potential PIMM issue, all the 12V rails (I assume) come from the 12V PSU, if your other 12V source looks good in the ENV table, and you still get a 12V PIMM error...I'd (personal option, no warranty in my statement) recommend temporarily shutting off ENV and booting anyway. If you can get to the PROM and Main CPU runs...then your CPU would appear to work fine, then it's likely a bad DS1780 on your PIMM (CPU card) and you can send me your PIMM for DS1780 IC replacement, it will be MUCH cheaper to do that than the entire mainboard was to send and we've learned what we need to put this time for shipping.
I am certainly excited to see what happens, go slow...take breaks...don't rush, that's how mistakes happen.
Cheers!
