[ILUG-BOM] Cannot detect card.

Is your card recognized as an ethernet card? Check the system log and make sure that cardmgr identifies the card correctly and starts up one of the network drivers. If it doesn't, your card might still be usable if it is compatible with a supported card. This will be most easily done if the card claims to be ``NE2000 compatible''.
Is the card configured properly? If you are using a supported card, and it was recognized by cardmgr, but still doesn't work, there might be an interrupt or port conflict with another device. Find out what resources the card is using (from the system log), and try excluding these in /etc/pcmcia/config.opts to force the card to use something different.
If your card seems to be configured properly, but sometimes locks up, particularly under high load, you may need to try changing your socket driver timing parameters. .
If you get messages like ``network unreachable'' when you try to access the network, then you have probably set up /etc/pcmcia/network.opts incorrectly. On the other hand, mis-configured cards will usually fail silently.
To diagnose problems in /etc/pcmcia/network.opts, start by trying to ping other systems on the same subnet using their IP addresses. Then try to ping your gateway, and then machines on other subnets. Ping machines by name only after trying these simpler tests.
Make sure your problem is really a PCMCIA one. It may help to see see if the card works under DOS with the vendor's drivers. Double check your modifications to the /etc/pcmcia/network.opts script. Make sure your drop cable, ``T'' jack, terminator, etc are working.
