Abstract

Disclosed is a solution for allowing access to very low level internal chip information from remote hardware without re-booting the system. This hardware, not normally connected to a dedicated Service Processor (SP), can be connected "on-the-fly". If the remote hardware is identical to that used locally, this method has the additional benefit of allowing reuse of the same debug software. This "on-the-fly" Connection is de-gated to prevent glitching and gated in a way that the Service Processor attached to the System is not aware that the "on-the-fly" connection has been made.
