Do you have evidence that the motherboard can boot from nmve at all?
If the motherboard in question is of a similar vintage to those 10 year
old boxes of rust, then it might not be able to, and you might need some
kind of SATA (or perhaps USB) device to boot.
Well, the AMI BIOS talks about UEFI so I just ass-u-me'd ...

See the biosboot sub-command in "man gpt", that's all it has ever taken
for me, perhaps along with a suitable installboot (I'm not sure if gpt
installs that one or not, it does install the PMBR boot code).
OK, I apparently tried this a long time ago, and I have a copy of
x86 BIOS Boot from vintage 9.99.82 or so... :) With no disks
attached, the system boots that code. Nothing seems to indicate
that any UEFI boot attempt was made.
Some bios's apparently require the PMBR partition (that is, the protective
MBR partition) to be marked "active" in order to boot from it.
Looks like that was already done, too.
If the BIOS can do UEFI booting, as Michael suggested, (and it works)
then that's a better way.

For BIOS booting it would be irrelevant.
I guess that once I update to newer BIOS Boot, it will process my
boot.cfg file appropriately.
