I am trying to get this rack server booted. I have added a EPYC 9654 processor and 8 dimms. Both the memory and processor are said to be supported.
I get stuck with a post code of 0xAb and no video. I tried clearing the CMOS but the instructions are not clear. I removed power and the battery and shorted the very tiny solder bumps on the board. I think it may have done something as a long memory training happened after that (0x15).
I have two crucial Gen 5 M.2 (the ones from the compat list) I added to the system. No hard drives.
Looking for tips on how to debug further.

So with a video card installed in the riser slot I can see that the system does post. I updated the bios to the latest version. Still no luck with onboard video.
