SSE won't be enabled anyway unless you've defined CPU_ENABLE_SSE in your kernel. The only reason I do this is that mplayer might use SSE to run a little faster. If you really want to know what they are, the SSE instructions can be seen at http://www.cpuid.com/sse.htm. The original patch related to the Athlon problem was posted to freebsd-audit January 22 - search http://groups.google.com/groups?hl=en&group=mailing.freebsd for "CPU_ATHLON_SSE_HACK". -David To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
