Glad to see someone so excited about UEFI.
I guess this is the time where I'll point out that it's a spec and that it's
the responsibility of the vendor for the implementation. If you're new to UEFI
it's easy to get caught up in it's capabilities, but remember that it's not a
magic wand.
The only people that can legitimately say they were "forced" into EFI are the
ones building Itanium systems.
Long and the short of it, if you're seeing stability and compliance issues on
your system, it's much more likely these are problems with your system.
If you really want to test this, run the SCT on it and if you see problems,
contact HP or Insyde.
Who knows maybe some of them are lurking on this list?
Out of curiosity, what exactly are you attempting to do?
