SKuzzy when I look at my device manager in win 2k this is what I see on IRQ 9. My modem, my video card, my sound card, AMD 756 PCI to USB Open host contoller, ACPI compliant system. I do not have ACPI enabled in Bios, I have tried removing and reinstalling the devices, and at first it does assign a new IRQ to some but when I install the last one it switches them all to IRQ 9 again. Anyway around this to get them to a different IRQ setting? I am thinking this might be the reason why I cannot fly . It all started with the US robotics modem I installed.
