2.8.3 Configuring an expansion card After installing the expansion card, configure the card by adjusting the software settings. 1. Turn on the system and change the necessary BIOS settings, if any. See Chapter 5 for information on BIOS setup. 2. Assign an IRQ to the card. Refer to the tables below. 3. Install the software drivers for the expansion card. Standard interrupt assignments IRQ Priority Standard Function 0 1 System Timer 1 2 Keyboard Controller 2 N/A Programmable Interrupt 4* 12 Communications Port (COM1) 5* 13 Sound Card (sometimes LPT2) 6 14 Floppy Disk Controller 7* 15 Printer Port (LPT1) 8 3 System CMOS/Real Time Clock 9* 4 ACPI Mode when used 10* 5 IRQ Holder for PCI Steering 11* 6 IRQ Holder for PCI Steering 12* 7 PS/2 Compatible Mouse Port 13 8 Numeric Data Processor 14* 9 Primary IDE Channel * These IRQs are usually available for ISA or PCI devices.
