I've switched a card to another PCI slot and it's using another IRQ. Thanks lots! Manu "Christopher D. Reimer" wrote:

Have you tried switching one of the cards to a different PCI slot? Depending on the motherboard, a pair of PCI slots will share the same interrupt. If you move a card to a different slot, both cards should have different interrupts.

Also, in the BIOS, have "PNP OS" set to "no". The BIOS will set up the interrupts in the most logical order and linux will be force to accept the results. This should fix most PNP issues.

Hi,

I'm trying to configure and ISDN card on a SuSE Linux 6.4 box and I have problems with the IRQs.

The problem is that I've a 3COM 3C905B NIC with IRQ=10 and io=0xdc00, and a Dynalink ISDN card with IRQ=10 and io=0xda00 and I'm not able to use both cards at the same time.

I've tried to unload the 3c90x.o module as the SuSE documentation recomends (to test the configuration) and the isdn card works, but then I'm not able to use the ethernet.

I've tried to change the BIOS configuration, but both cards always get the 10th IRQ.

Any idea?

Thanks in advance,

Manu
