We're running a "near-final" pre-release 8.0 that correctly identifies a 433s as 9000/43s. Note too, that uname -a now displays the following info: >> >> HP-UX NODENAME B.08.00 B 9000/43s LAN_LLA ^^^^^^^ Where LAN_LLA is the hex link-level address of the lan card. I believe this serves as a machine id which will be used to provide security for the new OS distribution procedures (DAT and CDROM). -- Paul B.
