What else can I help you with?
IRQ settings for the PS2 mouse?
The PS/2 mouse typically uses IRQ 12 for its interrupt requests. This IRQ is dedicated to the mouse, allowing the system to efficiently handle input from the device without conflicts with other hardware. In most modern systems, IRQ settings are managed automatically by the operating system, so manual configuration is rarely necessary. However, in legacy systems or specific configurations, it may be important to ensure IRQ 12 is not shared with other critical devices to maintain optimal functionality.

List interrupts used with the IBM PC type sytems?
IRQ 0 - System timer. IRQ 1 - Keyboard. IRQ 2 - Cascaded signals from IRQs 8-15. IRQ 3 - COM2 (Default) and COM4 (User) serial ports IRQ 4 - COM1 (Default) and COM3 (User) serial ports IRQ 5 - LPT2 Parallel Port 2 or sound card IRQ 6 - Floppy disk controller IRQ 7 - LPT1 Parallel Port 1 or sound card (8-bit Sound Blaster and compatibles) IRQ 8 - Real time clock IRQ 9 - Free / Open interrupt / Available / SCSI. Any devices configured to use IRQ 2 will actually be using IRQ 9. IRQ 10 - Free IRQ 11 - Free IRQ 12 - PS/2 connector Mouse. IRQ 13 - ISA / Math Co-Processor IRQ 14 - Primary IDE. If no Primary IDE this can be changed IRQ 15 - Secondary IDE These are just a set of standard IRQs. For much more detail check our Ralf Brown's list located at http://www.cs.cmu.edu/~ralf/files.html
