Abstract
A number of correctable and uncorrectable errors, including machine check aborts and system-hang events, may occur during the pre-boot stage prior to operation of an operating system. Outside of a laboratory environment, for example, in the field, it is very difficult to obtain this error information. By logging the error information during the pre-boot stage, the logged error information may thereafter be transferred to an appropriate media or over a ii network for subsequent analysis. This pre-boot logging and subsequent retrieval may enable correction of pre-boot errors that otherwise may go unanalyzed and repeatedly reoccur.
