Hi, If you used setpci for configuring internal modems on Linux, can you tell me if (and how) I can use setpci to set IRQ for the PCI card. I have internal modem 56FW-92 from BestData which is hardware flow controlled. My lspci -vv output shows IRQ 0 for the Communication controler. I wanted to set it to IRQ 10 I have been trying to configure this modem since two days and has been very frustrating.. Any help is very much appriciated.. Thanks.

You're in luck(?) Last week I didn't even know the "pci" utilities existed, but I've been doing some modem research of my own. You don't usually WANT to override the IRQ for a PCI bus device. One of the primary reasons we WENT to PCI was to escape the IRQ/DMA/address conflicts. PCI IRQ's are sharable, unlike the old ATA IRQ's. Actually, having the IRQ show up as "0" makes me wonder if the device in fact has IRQ capabilities at all. Winmodems are notorious for their dependency on the CPU, and it's possible that this device is polled rather than interrupt driven.
Sometimes the only way things ever got fixed is because people became uncomfortable.
