Changing /etc/pcmcia/config.opts?
Hi everyone, I'm on the last leg of my (seemingly hopeless) quest to get a Linksys CardBus card to work in Linux. After receiving advice from you guys I almost skipped ordering it, but Linksys had a link to a driver project for the cards (and that site claimed that their driver did infact work). Sadly, I haven't been able to figure out one of the most critical parts - how to get it to work. Apparently the problem is that the pcmcia card manager recognizes the card but it is not properly assigned an IRQ and I/O address. This results in an error when it the service tries to install it at boot, or via modprobe. The tulip driver people suggested that the problem was in /etc/pcmcia/config.opt's setting for IRQ's, but I'm at a loss at what I need to do. Does anyone have any suggestions? Thanks, Tim -- ----------------------------------------------------------------- Timothy R.

There is a utility which comes with the pcmcia pkg (or at least used to) called 'dump_cis'. Try it to see what information it can get from the card. I have a SMC8020 modem / ether combo that won't work because the mfr didn't build the card with the capability to answer system req's about IRQ and mem i/o addr. It is apparently an earlier design of the card, as it is listed as a compatible card for the pcmcia pkg. Others have had the same problem, so it's not just me. IOW, although others may be using cards of the same model as yours, your card might not work if the design was changed after yours was made. ---------------------------------------------------------------------- John Karns jkarns@csd.net
Hi John, Thanks for the reply! After I received your tip, I booted up my laptop to see what I could find.

Disclaimer: I'm no expert at this. The following is just my educated guess. Is that the entire output? If so it would appear to me that you may be out of luck. Here's the output from one of my cards.
