HOW TO FREE AN IRQ
If you do not have a Plug and Play Motherboard or you still
do not have a free IRQ
If you do not have a Plug and Play Motherboard or you still do not
have a free IRQ you might need to disable some unused
Hardware. For instance if you have a PS/2 or USB Mouse then
you might be able to disable your COM Ports.
Perform the following steps to disable your COM Ports.
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. Under the heading "Integrated Peripherals," look for
"Serial Port 1 or 2" or "COM Port 1 or 2."
4. Change the setting to "Disable."
5. Go to the heading "PNP/PCI Configuration."
6. Make sure the setting for "Resources Controlled
By" is set to "Auto."
7. Change the setting for "Reset Configuration" to
"Enabled."
8. Hit the "ESC" key and go to the heading "Save and
Exit."
9. Let Windows load and follow the steps in "Checking
for an Available IRQ."
