Hi list, I'm implementing FPU/MMX/SSE support in Minix 3 and not sure what mode for exceptions handling should be used: MS-DOS compatible or native. Why does GNU Mach use MS-DOS compatible mode (I didn't find any place, where CR0.NE is set)? Intel manual highly recommends using native mode, also you can't use MS-DOS compatible mode in multiprocessors PCs (probably in multicore too).
Thanks in advance for all answers. -- Best Regards, Evgeniy
