If you'll notice, he's got a '686-class' cpu and there is no LM (long mode) in the AMD Features flag. He's running FreeBSD/i386, not /amd64, on an Athlon-XP mobile, not an Athlon64. It might be a cut-down K8 core, but its not got 64 bit on it. -- Peter Wemm - peter@wemm.org; peter@FreeBSD.org; peter@yahoo-inc.com "All of this is for nothing if we don't go to the stars" - JMS/B5
