A shared-IRQ user-defined interrupt signal handling method and system is proposed, which is designed for use with a computer platform to allow a group of peripheral devices connected to an interrupt-configurable peripheral interface to share system interrupt lines IRQ with another group of peripheral devices connected to an interrupt nonconfigurable peripheral interface; which is characterized by the provision of an interrupt configuration table for defining a virtual device for the interrupt-configurable peripheral interface as well as each specific system interrupt line that is shared by the two groups of peripheral devices. This feature allows system interrupt lines IRQ to be shared by the two different groups of peripheral devices, and also allows the implementation to be easier to carried out than prior art without involving complex and difficult BIOS coding.
