Is there a way in windows to change IRQ's?

[VenomXt]

I have a guy that has a video card and a USB modem listed on the same IRQ (16). He was went into bios and all it tells him is the used IRQ's. Is there any way in windows to change the IRQ for a device or does he have to play plug and play with hardware to get a new hardware profile.

Messing with IRQ's is a bit sketchy, but can be done. If the Video Card is PCI, try a different slot first. If it's AGP, that probably isn't an option.

If you want to change the IRQ Settings, do this.

1. Right click on the device list and then select properties
2. Click the Resources tab
3. Remove the check from the Use Automatic Settings option
4. Select a non-conflicting configuration from the pull down box
5. Click OK

You may find you cannot manually change your IRQ settings (the Use automatic settings will be greyed out), this is usually related to the ACPI function used by Win XP.

Wil have him try it at home. I will post the results. Thanks

No, and you dont need to. Interrupt 16 means its using APIC to route IRQ requests and that you're both looking in the wrong place for a solution to a problem.

care to explain a bit more?

 

[LordOfLA]

nope. Google

This time its a case of Intel's engineers really do know more than you even if you'd like to think otherwise in recent year

Edit: eating cherry pie and custard while posting is bad for your spelling

Edit 2: but spelling custard wrong with both hands free is just plain dumb

Edit 3: To make your search shorte - the original PC only had 15 interrupts, had to fit into a single 8bit value
