    Interrupts

    The following table suggests a logical interrupt mapping of interrupt sources. It reflects a typical configuration, but you can change these interrupts. Use the information to determine how to program each interrupt. The actual interrupt map is defined using configuration registers in the I/O controller. I/O Redirection Registers in the I/O APIC are provided for each interrupt signal. The signals define hardware interrupt signal characteristics for APIC messages sent to local APIC(s).

    Note: If you disable either IDE controller to free the interrupt for that controller, you must physically unplug the IDE cable from the motherboard. Simply disabling the drive by configuring the BIOS Setup utility option does not make the interrupt available.

    Interrupt I/O APIC Level Description
    INTR INT0 Processor interrupt
    NMI N/A NMI from PIC to processor
    IRQ1 INT1 Keyboard interrupt
    Cascade INT2 Interrupt signal from second 8259
    IRQ3 INT3 Serial port A or B interrupt from SIO device (you can configure either)
    IRQ4 INT4 Serial port A or B interrupt from SIO device (you can configure either)
    IRQ5 INT5 Parallel port II
    IRQ6 INT6 Diskette port
    IRQ7 INT7 Parallel port
    IRQ8_L INT8 RTC interrupt
    IRQ9 INT9 Signal control interrupt (SCI) used by ACPI-compliant operating system
    IRQ10 INT10  
    IRQ11 INT11  
    IRQ12 INT12 Mouse interrupt
    IRQ13 INT13 Co-processor interrupt
    IRQ14 INT14 Compatibility IDE interrupt from primary channel IDE devices 0 and 1
    IRQ15 INT15  
    SMI_L   System management interrupt - general purpose indicator sourced through the PID to the processors
