FreeBSD 8.0-RELEASE #1: Mon Nov 23 13:47:06 EST 2009 amd64 It's a turion x2 of 1990MHz I only had windows on long enough to burn one CD back in February, so I have not the least clue how it behaved (besides terribly). I can't find any way to get the actual temperature values under Opensolaris, but I do dual boot. It spends so much time starting so many mind-bogglingly worthless services prior to giving me a log-in prompt that I'm not sure the comparison is fair. The fan usually kick into high prior to the log-in prompt, though. Opensolaris is pretty horrible in terms of performance and battery life compared to FreeBSD. It's also like a strange, alien wasteland what with bash & gnome & other linuxisms, except pfexec. pfexec rocks. --=20 --
