Abstract
A computer apparatus and a method of diagnosing are provided that increase reliability and make non-stop operation possible even at a hardware repair, replacement, or addition time. The computer apparatus, which comprises a main OS and a sub OS, may have a peripheral device or an I/O card repaired, replaced, or added with power on. The repaired, replaced, or added hardware component is disconnected from the main OS. With the main OS performing usual processing, the sub OS uses a test/maintenance program to check the operation of the repaired, replaced, or added hardware component and then passes the control of the hardware component to the main OS.
