: I'm trying to get pccards working on my Dell Inspiron 5000, and I'm a tad

Arun-
Is your Inspiron basically set up? I would stongly recommend doing
the following:
1) change the pcic entry in you kernel to
device card
device pcic0 at isa?
this will force the pcic into polling mode and free up irq 10.
2) Chances are irq 3 is free and clear.
3) If you don't use your onboard serial port, you can disable it in
the bios and gain irq 4
4) On some machines, irq 9 is free. Watch out for USB controllers
or video cards (in your case no video to worry about).
5) dmesg | grep irq
ought to give you some clues as to what is free, so will the
Windows device manager (if you still have windows).
6) I also recommend using a pared down pccard.conf file with only
the cards that you are going to use (helps with debugging) and
call it /etc/pccard.conf
a) add
pccard_conf="/etc/pccard.conf"
to /etc/rc.conf
b) make sure that the irq entry has _only_ free irqs
note: if you have an old version of pccard.conf, neither 8 nor
13 is free
you shouldn't have 5 or 11 in there either.
7) Do you plan on using a pccard modem? If so, change all of the
device sioN at blah blah
to just one single
device sio
If you plan on using the onboard serial port, simply add
options PNPBIOS
and your serial port will be automagically picked up as long as
it is enabled in the bios.
Hope this helps,
S
