unsharing IRQs in Windows 2000

[deseqer]

ran across <a href="http://nwn.bioware.com/forums/viewtopic.html?topic=55736&forum=49&highlight=chop piness" target="_blank">this</a> information while trouble shooting a gaming issue, was wondering If anyone else has tried this? if so did help resolve the issue or did it make things worse?

Click on the Hardward/IRQ tab.
See if some of your devices are sharing one IRQ. (5 devices were sharing my 9th IRQ).

Once you've verified this is the case, then this solution should work for you. MS says Win2000 can share multiple IRQs with no problem. Based on hard evidence, I can say this is a load of crap.

Step 2:
Control Panel/System/Device Manager
At the very top, expand the Computer heading. Select the ACPI device, and choose properties. Choose Driver, and update Driver. Then select "Choose driver from a list". Then select "Standard PC" from the available settings.

Then you'll have to reboot.
What this does is denies Win2000 the ability to make use of your Motherboard's ACPI functions. One of which includes IRQ management. After you reboot, Windows will start detecting and installing each device, one at a time. You'll have to reboot a bunch of times, depending on how many devices you have installed. Reminds you of Win 98, doesn't it?

I have indeed done this. I had like 5 devices on the same IRQ and wanted to change them. Make sure you have all your drivers handy like it says.

Also, it may disable some of the ACPI functions, like powering-down.

And if you are really unlucky you have to reload 2k, it doesnt always take kindly to having its acpi removed.

OK thanks for the replies. This is one of those tweaks that I am not sure about. (not sure that I want to reload or to have shutdown problems.) unless I get desperate to solve a problem this tweak will probly sit on the back burner.
