hi, just chat here... how much faster will a duo core CPU gives me when running freebsd, nothing optimised..
1. You need to rebuild the kernel with SMP support. 2. The correct names are; Core Duo, Core 2 Duo, Core Solo, and Core 2 Solo. 3. Add this to /etc/make.conf: CPUTYPE?=pentium3 CFLAGS+= -mtune=prescott COPTFLAGS+= -mtune=prescott * Change prescott to nocona if you have a Core 2 chip, although it doesn't really matter, EM64T support is ignored with FreeBSD/i386 and it's on by default with FreeBSD/AMD64. Moreover it's only being used with -mtune which means it does not change the ABI or the set of available instructions.... Those two are set via CPUTYPE and -march=cpu-type... don't set CPUTYPE or -march higher then pentium3 because higher settings have been known to screw up stuff at compile time. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
