Service Adapter with Internal Command Buffer

In computer systems which utilize a service adapter as an interface between the main processing system and a system controller, the adapter is usually a slave to the controller and merely executes commands received from the controller.

Incorporating a command buffer (comprised, for example, of a read-only storage array) within the adapter will enable the adapter to generate command sequences without reference to the controller and to initialize the controller.

A primary advantage of this approach is that it enables the adapter to initiate various system tests, despite malfunctions in the controller and various associated hardware.
