A method provides exception handling for a computer system. As an error in the computer system's hardware is detected, an exception vector pertaining to the hardware error is determined, and execution flow is transferred to a dispatcher that corresponds/pertains to the exception vector. A specific instance of a plurality of instances of a main exception handler is selected, and the specific instance of the main exception handler is executed. The actual exception handler thus contains two distinct parts, a dispatcher, which is unique and preferably resides in a safe memory region, and a main exception handler, multiple copies of which reside in an unsafe memory region.
