x86: Machine does not recognize BIOS boot, UEFI boot does not go into boot manager.
We have to support a 64-bit machine type which is new enough to have UEFI support, but (to keep things simple logistically with the other 32-bit machines we have) run the x86 distribution of Alpine.
I have had quite some problems booting the Alpine USB boot media (created with Rufus on Windows from the official ISO images). Being an aptio BIOS the devices needs to be recognized to be present in the Save and Exit menu for booting. On this machine only the UEFI bit on the USB key is shown, and it returns to the BIOS almost immediately after selection. I have seen that a failed boot on something else fell through and then booted then USB-key so I could install.
Parallel to this I am investigating if there are settings to tweak in the bios, but I would like to know if UEFI is officially supported for x86 media as of 3.14?
