HOW TO FREE AN IRQ
What to do if you don’t have an available IRQ
If there is not an available (open) IRQ on your system, you can
do the following:
The first thing you can do is let your Motherboard and Windows
do the work for you. For this option you will need to check that
you have a Plug and Play compatible Motherboard and set it to
reset the configuration.
Note:
All of the setting names below may not be the exact word-
ing on your system. This is due to the great number of
Motherboard and hardware manufacturers. The settings may be
listed on your system using different words that mean the same
thing. Refer to your motherboard manual or contact the manufac-
turer if you are unsure.
Perform the following steps to check for a Plug and Play
Motherboard and to reset the configuration.
1. Reboot your computer.
2. When your computer is going through its POST
(Power On Self Test) enter into your BIOS(Basic
Input/Output System).
3. Some BIOS’s have a setting that will let you
enable the Motherboard for Plug and Play. You
should look for a setting that says “Plug and
Play OS.” “Enable” this function.
4. The second setting to look for is under the
heading “PNP/PCI Configuration.” Under
this heading check to make sure that “Resources
Controlled By” is set to “Auto.”
