> Is there an easy to to tell if the BIOS has detected SSE on athlons? Look at the Features line in /var/run/dmesg.boot and see if it contains SSE: Features=0x383f9ff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,MTRR,PGE,MCA,CMOV,PAT ,PSE36,MMX,FXSR,SSE> If it doesn't then the BIOS may have forgotten. If you check the "Id = " number on the previous line of dmesg.boot and the id looks like "0x66y" or "0x67y" then this patch should help. To actually use SSE within FreeBSD you'll need the CPU_ENABLE_SSE option too. David. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
