I installed Unraid on a Supermicro build a few months ago and ran a successful memtest, but since then have not powered on the server. Yesterday I powered on the server again to start using it again, but it would not boot into Unraid. After attaching a monitor, I found that I was getting stuck on an American Megatrends screen.
After booting the server, I get the Supermicro text screen followed by an American Megatrends screen, which states
“The IMC is operating with DDR3 1600MHz
press <DEL> or <ESC> to enter setup”
However, pressing either of those keys does not work even though it states “Entering setup…”
I don’t see any prompts to enter the BIOS prior to any of these screens, so I’m not sure what to do. I’m not sure where to continue from here as far as debugging goes, or even what might be causing the underlying issue
