IBM P/N SC30-3383-03 39F9353. It's really cryptic stuff. You'll also want to have the IEEE 802.5 spec handy, and the spec that talks about source routing. It's been a while since I hacked token-ring hardware, so I don't know if there is updated info from IBM on their PCI cards. /Mitch. >-----Original Message----- >From: Matthew N.
