Second, is a 3com 3c900 PCI. Its behavior I do not understand. With
most
10-base-T cards, as soon as the system has power the connection light
will
be lit. But with this card, it does not. This card works in windows
(it is
PnP I am told), but the connection light does not come on until after
the
Windows splash screen closes. In Linux, it appear to find and set up
the
card, but the connection light did not light and it was unable to
connect to
the network (local or remote). Pinging a working result resulted in an
error. In QNX RTOS, it appear to auto detect the card, so I went to
network
cfg and entered my local network data under the network tab. Under the
device tab, I checked the box to activate this device, but still the
connection light on the card did not light. What is windows doing that
allows this card to “come alive” that the other two operating systems
are
not doing?
…
I only have a 3C900 Combo card and it works fine with the el900 driver.
Please post the output from ‘nicinfo’ as well as ‘pci -v’.
Here are the results of the output of nicinfo and then pci -v. The media
rate and LAN both being 0 strikes me as strange. Also, the PCI index is 0,
though I have no idea what they should be. Thank you for the help.
