Abstract
The present invention provides method and system aspects for performing error data gathering from fault isolation registers of a computer system following a machine check occurrence. A method aspect includes utilizing firmware to perform failure information retrieval in software accessible registers and initiating a service processor (SP) for failure data retrieval in non-software accessible registers. The method further includes coordinating the combination of the failure information retrieved and the failure data retrieved in an error log for use in isolation of a fault source in the computer system.
