Abstract

Disclosed is a method to allow manufacturing ROM code to replace system ROMs without requiring their removal. This method relates to a PS/2 computer which has ROMs on the system planar containing the power-on self test (POST) and the basic input/output system (BIOS). Upon initial power-up, the system is controlled by the code in these ROMs.
