I have an EtherExpress PRO/100 Mobile Adapter 32-bit CardBus card that
I'm using with RH 8.0. The card and tulip driver (tulip.c:v0.95
6/21/2002) work when connected to a 10Mbps HDX network, but not at
100Mbps FDX (one network is a 10Mbps hub, the other a 100Mbps switch).
The driver in RH 8.0 did not work at all, so I downloaded and compiled
pci-scan, tulip and tulip-diag from scyld. Below I've included the
output from 'tulip-diag -eee' after installing the tulip module, and
after initializing the network.
With the card connected to a 10/100 autosensing port, I invoke 'modprobe
tulip', then tulip-diag reports:
