Abstract
A method for testing I/O ports of a computer motherboard under test. A non-volatile memory on the computer motherboard under test is provided with a test code for initializing the computer motherboard and testing its I/O ports, in which the test code includes a plurality of test routines corresponding to the I/O ports to be tested. Upon power-up or reboot, the computer motherboard under test is booted from the test code in the non-volatile memory. One of the I/O ports is selected from an interactive display menu, and then a CPU on the computer motherboard under test executes the corresponding test routine for the selected I/O port to test it. If there is an abnormal signal pin in the selected I/O port, a failure message is displayed to indicate which signal pin of the selected I/O port is not operating correctly. Otherwise, a pass message is displayed.
