There never are in Linux. Use 'ifconfig -a' to determine what network

The drivers for *PCMCIA* LAN cards are in /lib/modules/2.2.20/pcmcia/,
I believe. And is the right one for the particular PCMCIA LAN card you
are using among them?

AFAIK, what should happen is that as soon as cardmgr 'sees' a PCMCIA card,
it looks it up in a "database of known cards", which is the file
/etc/pcmcia/config
If the PCMCIA card is indeed in this list of known cards, cardmgr will
find a few lines of further info on it, the last of which is the name
of the driver (loadable module) that it must 'bind' to the card.
If that driver is not found, one gets the state of affairs you describe.
Therefore:
- look up your PCMCIA LAN card in
/etc/pcmcia/config;
- check that the module in its 'bind' statement is present in
/lib/modules/2.2.20/pcmcia/;
- if it is, try again, and find out if and why loading of the module fails
using the output of 'lsmod' (to see what modules are actually loaded)
and the contents of /var/log/{syslog,messages} (to see what 'modprobe'
and/or 'insmod' report about loading of modules);
- if the module you need is not available on your system, then it was simply
not present in the pcmcia-modules package you installed. Probably, you
then need the package pcmcia-source, to compile your own pcmcia-modules
package for the version of the kernel you are using, after configuring it
to produce all the PCMCIA modules you may need.

Sorry, I cannot help you with this one. No experience with flash cards.
