Best way to confirm a dead board in any case is those POST diagnosis cards. They have a dual-digit LED output that changes depending on the signal on the wire. If at any time those dual-digit LEDs stay permanently on anything OTHER THAN 00 is a failed POST. If it fails before it gets a shot at testing RAM or anything, there may be no beep codes. Always good to have one in a toolkit. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
