Abstract
A method and a system for automatically diagnosing disability of computer peripheral devices are provided. In the method, a set of interrupt configuration data relevant to a disabled PCI peripheral device, including relevant setting values of a hardware IRQ routing, is input and compared with a PCI IRQ routing table pre-stored in a boot control unit. Then, whether errors exist in the current setting values of the relevant control parameters and flags of all the relevant control units are automatically checked. If an incorrect setting value is found, a corresponding diagnosis result message is displayed for informing the user to make a modification. Therefore, users can know the reasons that cause the computer peripheral device to operate abnormally and make the modification quickly and effectively.
