The ACT (ACTivity) LED should flash as data is sent across the
network.
The 10 or 100 (Mbps) LED should light, showing the speed of the
connection: the cards should try to negotiate a 100 Mbps connection
first, and fall back to 10 if that fails.

Danger, Will Robinson! The 3C905, 3C905B and 3C905C cards use
totally different chips, and last time I looked there was not a
single unified driver set that worked with all three -- nor did
3com's installation software do an acceptable job of verifying that
the driver version was correct for the hardware actually present.
It would be terribly easy to "successfully" install the drivers for
the wrong card.
