Windows XP BSOD with MMX CPU on ARM

Post by RichardG867 »

On PCem vNext 1905187, compiled for ARM64 (with a workaround for incorrect architecture detection per GitHub issue #102), Windows XP does not make it to second stage setup when a Pentium MMX CPU is selected, with a TRAP_CAUSE_UNKNOWN BSOD right as the GUI is supposed to be brought up:

Switching to a non-MMX CPU allows setup to proceed:

I have also tested Windows 2000, and this issue does not happen there.

Update: ARM32 build does make it to the second stage, which quickly fails, on both MMX and non-MMX CPUs:
