Abstract

Microcode released in the field may include errors. The discovery and rediscovery of these errors and the length of time to produce a new read-only store (ROS) and get it to the field demands a quick method of correcting these errors. Buried IPL (Initial Program Load) and patch card are too expensive for low-cost, high production machines. This is a method for machines having storage and loading facilities.
