Hi, >mii - media independent interface. does your card have an MII port, too? Some cards (many of the DEC 2114[023] devices and the Intel Pro100/B at least) have an on-board MII-compliant PHY device that controls the physical layer interface (ie, its what is wired to the TP connection on the board). It'll do things like auto-detect the network speed and duplex mode. There IS a standard MII connector. The idea behind this (as far as I understand) is given a particular NIC, you can plug a different MII PHY into it, and use the card with a different medium. Eg, get a Fibre, 10-BaseT, 100-BaseTX, or 100-BaseT4 PHY, and plug in to the wire. Hope that helps. -- Peter.
