Unfortunately not. More data on this bulkhead: It contains a black plastic module that calls itself: ALL-IN-ONE Ethernet COAX TC3095 along with a 20Mc xtal oscillator. It looks like this is a selfcontained DC-DC converter, pulse xformer and a 10base2 medium interface in a single module. The cable connection to the PCI riser goes to a connector labeled "AUI". My best guess is that this bulkhead is not much more than a 10baseT/10base2 transceiver in disguise, connected to an AUI interface. I'm currently performing surgery on my other machine to see what the 10/100 bulkhead contains. -- Wilko Bulte FreeBSD, the power to serve http://www.freebsd.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
