Abstract
A method of linking peripheral devices to a single interrupt procedure in a computer is comprised of storing in an interrupt vector table of a BIOS ROM, a first pointer to an interrupt service routine related to one of a group of peripheral devices which use the same interrupt request (IRQ) on the same software interrupt vector, and storing further pointer in each one of the peripheral devices to another unique one of the peripheral devices in the group.
