So... there was a problem with some commonly-used UEFI BIOS core that
would lock up on "localboot 0". I actually implemented a hack which
would try to detect a UEFI-based BIOS (keep in mind, detecting the UEFI
underneath the BIOS CSM layer is a bit complex) and actually change
"localboot 0" to "localboot -1". Unfortunately that quirk seems to have
broken other machines, which makes it very hard to deal with.
At this point writing a Lua script detecting the offending machines and
choosing between localboot 0 and localboot -1 might be the best option.
It would definitely be interesting to get more comprehensive
information of the offending machines.
