ABSTRACT:
Provided are a method, system, and program for initializing a processor of a computer system, to enumerate a remote bus and remote devices coupled to the remote bus, as operating components of the computer system. In another embodiment, a controller stores a message containing a directive in a memory shared by a processor of a computer system and the controller which may be operated independently of the state of said processor and said operating system. The processor may read a message stored in the shared memory by the controller and process the message. In addition, the processor may store a message intended for the controller to provide, for example, status information to be forwarded to another computer system. Other embodiments are described and claimed.
