(for a P4 machine) and in second one it is enabled by default so i dont need to add enable to kern. conf should i put options CPU_DISABLE_SSE for P2 and P3 machines? would not using disable option on a p2 machine with kern. conf like ******* ^^^^^^^ ^^^^ ******* enable p4 second couse any ill effects? like not being able to run the binaries compiled with -march=pentium4 ... and is this enable disable automaticly has anything to do with CPUTYPE option on the /etc/make.conf - - -- ilker -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQFA8+rcvxSBSqT0G9ARAo5hAJ0XrKQegK3CgjTdYANNxnNWD4waOACgwJ6X jaIl4wz2nPFXQKiBJ7WYap8= =qXjb -----END PGP SIGNATURE-----
