Yeah, added those since I was getting some odd core dumps and freezes when compiling atlas using the previous proc I had in here testing to see if that was possibly cuasing a problem with it.... just not removed them yet... eventually traced that back to something about my Abit NF7-S2 not liking the Athlon-XP 2400+ thorton core proc I had in here previously:/ > Features=0x383fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR > ,PGE,MCA,CMOV,PAT,PSE36,MMX,FXSR,_*SSE*_> AMD > FreeBSD already identifies it, or it could be because of your > options but I think not. > > options CPU_FASTER_5X86_FPU is for Cryix 5x86 Cool, thanks for the info. > http://people.freebsd.org/~kato/cpuident.html > > Also how does your /etc/make.conf look?

Those are for a 586(I think 586) class cpu Yeah, had to have it enabled for abit. If it was disabled X would freeze. I eventually traced the problem to something involving the AGP kernel module. I commented that out of loader.conf and I could then could then successfully start X without needing to disable the mtrr. :) Much thanks any ways :)
