*AMD Boards: Issues Getting to Boot Menu and UEFI [Rare, Just Want To Report It]*
This is an issue that will not affect most people but since it impacted me and it was a pain in the ass I thought I’d report it.
– Boards impacted: X670E and X870E Aorus (Gigabyte) since that’s what I have, possibly others – Symptoms: Boot logo screen freezes when pushing key for UEFI or Boot Menu
I discovered that this is only on UEFI versions that have AMD AGESA 1.2.0.3a or newer. Ones with 1.2.0.2b or older work fine. The issue is caused by NVMe RAID and only NVMe RAID. SATA and USB RAID I’ve tested to work fine. This is *software RAID* which means Windows Disk Management, Storage Spaces, etc.
– Solution: Remove the RAID drives temporarily to change UEFI settings or to boot to a different device via menu.
On AMD boards you may get the “0d” BIOS code with no POST after doing operations like this if certain values are changed. It’s due to an SMBus conflict which breaks memory training. Solution for this is to remove one stick (i.e. out of a pair), boot cleanly, shutdown cleanly, then return the stick.
I’m posting this because (a) people may need to get into the UEFI to enable Secure Boot for anti-cheat (e.g. BF6) and (b) I didn’t see this issue addressed clearly anywhere. Other users have had this and fixed it in other ways (using a different video output port or the iGPU, alternatively removing the boot drive or reinstalling Windows on it) which means this might not be directly caused by NVMe RAID. However, this is replicable on the boards mentioned above with specific UEFI revisions for me. It was extra fun finding and replicating this with the 0d nonsense (which *does* impact other AMD motherboards, but I believe fixed on ASUS).
