X10QBi

A SuperMicro motherboard supporting four LGA2011 CPUs and eight SuperMicro memory boards. The physical board comes in at least versions 1.01 and 1.21. It requires a SuperMicro AOM-X10QBi-A/L I/O board to boot (the card uses a proprietary slot). This card implements BNC/IPMI, offers two 10GigE ports via an Intel controller, and supports VGA.

Contrary to some information online, it boots just fine off a single CPU in Socket 1. It requires about five minutes to reach UEFI handoff, and goes through several dozen boot codes (some of them repeated) before doing so. Similarly, you can boot off any subset of CPU sockets, so long as there's one in socket 1.

Boot codes

If the machine immediately goes to state FF and doesn't leave, the CPU output ports are not being written to. You have either a bad motherboard, at least one bad processor, and/or at least one badly-seated processor.
