Hello, I have an Abit NF7-S motherboard with the network device built in on the board. It was detected during the Fedora core 2 installation (forcedeth driver) as you can check in the log below: Sep 4 12:51:35 kalimotxo kernel: Linux version 2.6.5-1.358 (bhcompile@xxxxxxxxxxxxxxxxxxxxx) (gcc version 3.3.3 20040412 (Red Hat Linux 3.3.3-7)) #1 Sat May 8 09:04:50 EDT 2004 [...] Sep 4 12:51:35 kalimotxo kernel: ACPI: Subsystem revision 20040326 Sep 4 12:51:35 kalimotxo kernel: ACPI: IRQ9 SCI: Edge set to Level Trigger.

If I play a little bit with the BIOS setup, PnP/PCI configurations, the resources are controlled by Auto (ESCD) by default. If I change this setting to Manual and I assign IRQ-10 to Reserved instead of PCI Device, then the network controller uses IRQ-12 and USB 2.0 controller switches to IRQ-5. This time it's the IRQ-5 which is disabled on Fedora and I have no problems related to the network.
