Question Seek laptop recommendation for 2 PCMCIA cards 

Forum: PCMCIA Installation and Configuration Issues

Hi !

I'm thinking of buying a cheap laptop on which I would want to run Linux. I plan to use 2 PCMCIA cards - a wavelan card and an ethernet card. I understand that there are issues with configuring 2 PCMCIA cards on Toshiba laptops - in fact I'm trying to help a friend sort through precisely that problem.

Does anyone have any suggestions on problem-free laptops in terms of installing 2 cards ?

Thanks !

None I haven't heard of that sort of problem before

I know of no problems with Toshiba or other laptops having to do with
handling two cards at once.

You can sometimes run into interrupt conflicts that only show up when
two cards are in use, but that is just a matter of adding the right
interrupt constraints to /etc/pcmcia/config.opts.  There is a section
in the PCMCIA-HOWTO about that issue.

Hi Dave,

	Thanks for getting back to me.

I tried setting "poll_interval=100", and also separately restricting the irq_list to the interrupts reported as unused in /proc/interrupts, and combinations of these, as you suggested in the HOWTO, but my Toshiba 1625 still fails to configure both cards. The first inserted card does okay, but the second one generates "RequestIRQ : Resource in use".

	Same problem with Compaq Presario 1925.

	With Toshiba 2180CDT, both cards worked after I downloaded the pcmcia3.1.17 version (which is now installed on all three)

	Any suggestions would be much appreciated.

	Thanks again,

-Chari.

I'd need to see the PCMCIA driver messages in each case.  You may want
to comment out some of the default interrupt exclusions from your
/etc/pcmcia/config.opts file.  Basically you just need to get the
appropriate number of free interrupts.  The i82365 driver reports
which interrupts seem to be available for its use.
