... SCSI Pass Through and SCSI IO Pass Through not available on the HP
laptop (only SATA drives, but SATA CD should be under one of them). Also
that hang on attempt to read from the internal HD went away (maybe a power
cycle cleared it - was doing it across reboots?).
Is UEFI implementation a bigger mess (in terms of proper, standardized and
reliable function on actual machines) than the old standardized BIOS was?
I have a feeling it just needs work because it was forced onto everyone too
soon. All I can do is report what I find and hope the implementations are
fixed up to make everything more robust.

UEFI is supposed to be the standard which consumers can purchase with
confidence that they could run any UEFI application on it and expect all
the support for it to be on the system. So now you provide specialized
single or multi-task hardware / software solutions without having to deal
with the headache of an OS. This is especially good for hardware vendors
and they should desire to be putting out fully implemented standardized
features of UEFI so UEFI apps will run on their hardware.
