Claim:
1. A method of isolating a fault in a computer system comprising: detecting an error in the computer system using a device driver installed in the computer system which controls an electronic device of the computer system, the electronic device being one of a plurality of devices which include multiple field replaceable units and are interconnected using a plurality of serial links adapted for interconnecting the field replaceable units; analyzing the error using fault isolation logic embedded in the device driver to determine first failure data and a logical error identifier for the error, wherein the logical error identifier represents a hardware logical area of the fault; associating the error with an error number using the device driver, wherein the error number represents an error type, and the logical error identifier is different from the error number; and mapping the fault to a segment of the computer system using the first failure data and the logical error identifier based on a self-describing system model for the computer system which is stored in a memory device of the computer system.
