Marc, At the risk of wading in where I know too little, it looks like you have an IRQ set in CMOS for the PCI video. This is not mandatory. Do you know if you need it? I use several Diamond Stealth PCI virge cards and have never found a use for the IRQ setting so I disable it. There should be a setting to disable IRQ for video in CMOS. You can also disable comm ports. Since your modem is using IRQ10, do you have serial devices on ports 1 and 2? I don't recognize the IRQ 11 device.
