APPENDIX A: Server Specifications Interrupts Important If you disable an IDE controller to free the interrupt for that controller, you must physically unplug the IDE cable from the system board. Simply disabling the drive by configuring the BIOS option does not make the interrupt available. The following table reflects a typical configuration, but you can change these interrupts. Use this information to determine how to program each interrupt. ISA Interrupt Description IRQ0 8254 timer IRQ1 Keyboard controller IRQ2 Cascade for IRQ9 IRQ3 Free IRQ4 Serial port IRQ5 Hot-plug SCSI controller IRQ6 Diskette controller IRQ7 Free IRQ8 Real-time clock IRQ9 Generic, Option for SCI IRQ10 VGA IRQ11 USB IRQ12 Mouse controller IRQ13 Numeric data processor IRQ14 Primary IDE controller IRQ15 Secondary IDE controller Connector pinouts Main power connector (J5) Pin Signal Name 1 +3.3 V 2 +3.3 V 3 Ground 4 +5 V 5 Ground 6 +5 V 7 Ground 88
