Hi Carl-Daniel, Thanks for the fast feedback. This BIOS has a UEFI boot option which isupports EFI booting an OS. Got it to work for a while and then somehow it managed to hose itself by adding one too many boot options. I suspect a buggy implementation of an EFI boot manager but Intel will not provide any support because (1) I was using Linux and (2) it is a desktop motherboard. I wanted to clean out the EFI boot options.
Guess I will just have to demand a replacement motherboard under warranty.
