I've recently installed an auto-config 10/100Base T switch, intending to connect my new G4 with my Beige G3 and the 1998 G3 Powerbook, both of which are 'supposed' to have 10/100base-T capability. However, neither of the older machines configures at 100base-T.
I'm using fully certified Cat 5 cables, and the G4 comes up with a full duplex 100b-T connection. I noted a 'Enet Speed and Duplexer Tool" at Apple's web site, but this only works with the Blue&White G3 and Bronze Powerbooks!
Any ideas greatly appreciated!
