Sorry for the repost... I don't think the first one posted.. posted to freebsd.stable, freebsd-current, Freebsd-hardware I checked the hardware in the online documentation manual/hardware It only lists the bits and peices of the machine say the hard drive controller and so forth. but doesn't give you a particular system to look at as a working machine with FreeBSD 6.2 does anybody
