Abstract
An apparatus for testing I/O ports of a computer motherboard. A non-volatile memory on a computer motherboard under test stores a test code instead of a normal BIOS code to initialize the computer motherboard under test and test its I/O ports. The computer motherboard under test is booted from the test code. For the I/O ports to be tested, a CPU on the computer motherboard under test executes test routines in the test code. The apparatus of the invention is connected to the computer motherboard under test so as to cooperate with the test routines in testing the I/O ports. Furthermore, the inventive apparatus includes connectors and test circuits for establishing electrical connections with corresponding pins of the I/O ports to be tested and checking each pin with the test routines.
