First time I'm ever using a SuperMicro H8SCM-F [1] with the Opteron 4200/4300 "HE" series. [2a] [2b] I'm trying to get the system to VGA output/POST and/or use the IPMI iKVM, I'll take either. I think I'm just overlooking and/or am ignorant of something with the VGA output.

Components under Test: (various combinations attempted)
- Brand new (3) H8SCM-F [1] with IPMI updated to 3.16 (originally 2.02) -- 3 different boards
- Brand new (1) Opteron 4256 HE 35W TDP [2a], and
used/pulled (2) Opteron 4332 HE 65W TDP [3a] -- 3 different processors, 1 for each boad
- Various PC3 and PC3L UDIMM and RDIMMs in pairs or quads, including
Brand new (1) Kingston KVR13LR9S8K4/8 (4x2GiB ECC RDIMM kit)
- Various ATX/SSB 2.x power supplies, including 8-pin Server and 4-pin P4+Molex w/8-pin adapter

I can get the IPMI to come up and access it via Web or the Java-based (using 1.6 for max compat) IPMIView software on all of them. I even updated IPMI to v3.16 (from 2.02). I have also attempted to pull the CMOS battery and shorted the CMOS reset, per manual.

I just cannot see the VGA output/POST, not after waiting for minutes. Whenever I use the Java IPMIView iKVM option, it opens the window, but says "No Signal." I've tried with the IPMI and/or VGA enabled and/or disabled, just in case I had the jumpers orientation wrong.

When I go to the sensors, it always lists the +5V, +12V and -12V to be "N/A". I get no sound from the internal speaker, the default shorted jumper setting. I also get no sound when I remove the jumper and plug in a speaker.

I've used a lot of pre-assembled SuperMicro systems in the past, and assembled lots of various boards, but this is the first time I'm using a SuperMicro mainboard on its own in a general chasis. I've looked to ensure the chassis is not shorting anything, yanked all cables sans power and the power switch/LED to ensure nothing is grounding anything.

I'm really at a loss at what I'm doing incorrectly. Anyone have any suggestions at this point? Thanx in advance. Also feel free to suggest a server-centric board. I'm attempting to register for the SuperMicro forums as well, although it doesn't seem to be too active.

Per SuperMicro, if the BIOS is old, it will only work with Opteron 4100 processors. The BIOS can only be updated on a booting system, and not via the IPMI.

I now have confirmed the system POSTs with only Opteron 4100 processors. I will be updating the BIOS on all boards and testing all processors this weekend.

Hope this finds its way into a Google search in case anyone else runs into it. 😉
