I recently upgraded my 7-year old SuperMicro board to a new one (A2SDi-HLN4F running firmware v3.6) and am having difficulty booting it - I believe due to UEFI issues.
Specifically I'd like to boot the trusty UltimateBootCD to run memtest and other system check tools, however I don't believe this will boot in UEFI (Non-CSM) mode. I would like to hope that the BIOS will let me boot non-UEFI software, but I can't figure out how to enable it.
I've set the "BOOT MODE" to Dual and Legacy but neither will display my USB boot drive (however, I should note that it does appear as an option in the UEFI boot menu, but it will fail to boot). Secure Boot is also disabled. What other settings do I need to change? (I'm guessing something with CSM but I haven't been able to find a setting for this yet).
Any help would be greatly appreciated as this is a hard blocker for me (am planning to run OpenMediaVault which also doesn't support UEFI at the moment).
Note: my USB boot stick works just fine on an older non-server UEFI PC motherboard I have, so I'm at a loss for what to do.
Thank you very much for your help!
PS - I've also noticed that it takes a darn long time to POST on this board - it's taking much longer than any non-server UEFI PC board I own. These PEI and DXE steps (part of UEFI?) take at least a minute to run through. Is there any way to disable/skip this?
