Typical Intel System IRQs

IRQ Device
0 System timer
1 Keyboard controller
2 Video graphics adapter (EGA/VGA)
3 Second serial port (COM2, COM4) or bus mouse
4 First serial port (COM1, COM3)
5 Second parallel port (LPT2, often sound card)
6 Floppy disk controller
7 First parallel port (LPT1)
8 Real time clock
9 Redirect to IRQ 2
10 Available
11 Available
12 PS/2 Mouse
13 Math coprocessor
14 Hard disk controller
15 Available (often network card or SCSI controller)

So only 10 11 12 available

To change IRQ Press windows and Pause key to get system propeties - hardware - device manager - right click the item to get properties - resources -select IRQ - change settings button - if its greyed out then you can not change as the device will not work on any other IRQ.
