So far it seems like it DID fix it, but give me another day or two to watch it to be sure. Thanks! FYI, it only changed the PROM on the first NIC on each PDSMi+ box; it said the second NIC was fine. (But since the first NIC was the one I was having trouble with...) I ran it on the older PDSMi boxes and it said it changed both NICs on those, even though they were (and still are) working fine. -- Mike Andrews * mandrews@bit0.com * http://www.bit0.com It's not news, it's Fark.com.
