Help with IRQ conflicts

[MrJoe]

I ran my system information utility and it came up withthe following.

IRQ 5 Intel(R) 82801BA/BAM USB Universal Host Controller - 2442
IRQ 5 ACPI IRQ Holder for PCI IRQ Steering
IRQ 9 Intel(R) 82801BA/BAM USB Universal Host Controller - 2444
IRQ 9 Kingston EtheRx Client PCI Ethernet Adapter
IRQ 9 Creative SB Live!
IRQ 9 ACPI IRQ Holder for PCI IRQ Steering
IRQ 9 ACPI IRQ Holder for PCI IRQ Steering
IRQ 9 ACPI IRQ Holder for PCI IRQ Steering
IRQ 9 SCI IRQ used by ACPI bus
IRQ 10 Intel(R) 82801BA/BAM SMBus Controller - 2443
IRQ 10 ACPI IRQ Holder for PCI IRQ Steering
IRQ 11 NVIDIA GeForce DDR
IRQ 11 ACPI IRQ Holder for PCI IRQ Steering
IRQ 14 Primary IDE controller (dual fifo)
IRQ 14 Intel(R) 82801BA Ultra ATA Storage Controller - 244B
IRQ 15 Secondary IDE controller (dual fifo)
IRQ 15 Intel(R) 82801BA Ultra ATA Storage Controller - 244B

Is this normal?? I'm not having any problems yet, but I would think with this many conflicts I will start. HELP !!!!!

Thanks

you'll be fine, because windows ACPI somehow manages devices who share IRQ's without giving conflict. if you disable ACPI though, most of your devices won't be conflicting anyway. the ones that do are normally solved through ACPI.

for example, I have a modem and a hollywood + which are on the bottom 2 PCI slots. unfortunately those slots share an IRQ, no matter what I do. my AGP port, and top PCI port also do the same thing. without ACPI, I would end up with major IRQ conflicts when trying to use both the H+ and modem.

What is ACPI and how do you check to see if it is disabled?

Advanced Configuration and Power Interface
it allows the computer to shut down non-essential drives for power comsumption reduction.

some bioses let you play with it,
under device manager, click on the plus sign in front of system devices and you'll find acpi power and acpi system buttons.
