It appears that the PCIC controller and the ATI display controller : both use IRQ 11. The LT winmodem and the ESS sound card both use IRQ 5 too, : but since there aren't any drivers for them that's OK if they don't work : :-). What's the procedure for resolving this? : 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.
