FYI, Good news. I unplugged all of my add-in cards, reset BIOS recovery
AND ME force update jumpers to 1-2 positions (4 jumpers total) and the damn thing booted up! I'm sitting at a BIOS screen now.
Keep in mind, I cycled through several different 1-2/2-3 jumper settings and pulled the CMOS battery during this period.
System information confirms that BIOS is the 02.06.0006 version.
Also want to report that previously in IPMI SDR version info was garbled, like the data was corrupted. It wasn't regular Alphanumeric characters. Now everything reads correctly. I was even able to customize the SDR to finally get the fans to spin down.
Info in IPMI as below:
BIOS ID : SE5C600.86B.02.06.0006.032420170950
BMC FW Rev : 01.28.10603
Boot FW Rev : 01.17
SDR Package Version : SDR Package 1.11
Mgmt Engine (ME) FW Rev : 02.01.07.328
This is on a board with PN PBA G56797-510
