IRQ Problems

Is it normal to have all these devices on one IRQ? I have all these on IRQ 9. Is this a problem?

Microsoft ACPI-Compliant System
NVIDIA Geforce FX 5200
Silicon Image SiI 0680 Ultra-133 Medley ATA Raid Controller
OPTI 82C861 PCI to USB Open Host Controller
Hercules Gamesurround Fortissimo(tm) II
National Semiconductor DP83820 Based Gigabit Adapter
Intel(R) 82801BA/BAM Universal Host Controller - 2442

Under normal circumstances, yes, it's totally normal.


What you have is ACPI - it stands for Advanced Configuration and Power Interface (i think)

It allows for the OS to share IRQs and do "virtual IRQ switching" as opposed to being limited to hardware only IRQs.

If you are doing professional audio recording or video editing, it is recommended to turn ACPI off (which most of the time requires a system reinstall). If the system works for you, just leave it the way it is.

Not if everything seems to be working fine. That's what ACPI does: Handles everything itself so you are not hampered by having a limited number of IRQ's. In the old days you often found yourself having to uninstall a card (what do you pick? Sound? NIC?), or had to reboot in a separate hardware configuration to make things work.

So, could this be the source for slow 3D performance among varios games? Or would all these devices on this one IRQ not cause any performance issues?

No, but that GeForce 5200 could be the source of slowness
