(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=20 second couse any ill effects? like not being able to run the binaries compi= led=20 with -march=3Dpentium4 ... and is this enable disable automaticly has anything to do with CPUTYPE opti= on on the /etc/make.conf =2D -- ilker =2D----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQFA89FEvxSBSqT0G9ARApQ2AKCLrSXFcJ5LeGsqfdB4Y/5hTCR75ACg83Mg t7kFnSoOgC5Qt7XOmZlvi9M=3D =3Dza1D =2D----END PGP SIGNATURE-----
