I updated my board to the latest BMC firmware (1.60) and the latest BIOS (3.31), but I’m not able to even detect any USB bootable drives regardless if I’ve set it to UEFI or Legacy or both. I’ve tried a few different USB drives with various images that boot fine on other systems…
The only boot option is the USB virtual device which is the KVM “CD image” mount, which does work as expected.
