    Default IRQ's

    Hey everyone,

    I am trying to use a tweak guide to optimize my OS and i remember reading many times to disable all unused IRQ's. When i go into system information and check my IRQ's i see the normal ones up to about IRQ22. Then from IRQ81 all the way down to IRQ190 it says "Microsoft ACPI - Compliant System". Every single IRQ is being used between those two numbers. It wasn't like that before. I know having all those will probably slow down my boot up time.

    Can someone explain why i see this, and what i should do about it?

    Thanks, Jerry.

    Chances are that windows is grabbing or reserving all unused IRQs. The suggestion to disabled unused IRQs probably refers to unused mobo hardware resources such as network connections, 1394, etc.
