This is really the wrong place. You want to be reaching out to the i915
developers at : dri-devel@???

It's not insisting you upgrade UEFI, it's attempting to say "Your BIOS
has mis-programmed the GPU. Maybe if you are lucky your vendor might
have a newer BIOS that does not do dumb stuff, so try upgrading".

My overall experience with this has been that in general the Windows
drivers don't care about the issue or else the BIOS would not have made
release, so your chances of a viable update are slim to none. Approach
the guys who actually write the driver and give them some useful
information to work with, and you might be pleasantly surprised with a
workaround or fix.
