Abstract

The Data Zap FRU (Field Replaceable Unit) provides a method whereby Manufacturing can automatically customize selected data and program FRUs during the processing of a sales order for a computer system. Diagnostic and machine function programs of most computer systems require specific machine feature information, such as size and speed of main storage, to function. Data Zap FRUs are used to customize CPU (Central Processing Unit) feature sensitive data in the initial microprogram load (IMPL) code for the computer system.
