[Jason Stewart]

Issue #327 has been updated by Jason  Stewart.

Know this thread is a bit old, but just wanted to add that this change fixed this issue for me. Just wanted to add some data points regarding my hardware and in hopes that it helps someone else in the future:

Sandy Bridge Lenovo W520 + I7 3840QM + Quadro 2000m. No VGA roms were used.

this line .. OperationRegion (OPRG, SystemMemory, ASLS, 0x2000)
the 0x2000 will cause BSOD ACPI_BIOS_ERROR when booting installer, os, etc

When set to 0x1000 windows UEFI tianocore mode boots fine
