Method for debugging keyboard basic input/output system (KB-BIOS) in a development notebook computing system

Abstract

In a computer-implemented method for debugging keyboard basic input/output system (KB-BIOS) in a development notebook computing system, a serial PS/2 port, that is connected to a KB-BIOS processor and that serves as a communications channel, of the development notebook computing system is coupled to a host computer so as to establish communication between the KB-BIOS and the host computer. Thereafter, a debug command is sent from the host computer to the development notebook computing system via the serial PS/2 port. Subsequently, at the development notebook computing system, the debug command sent by the host computer via the serial PS/2 port is directed to the KB-BIOS processor so as to enable the latter to execute the debug command according to program instructions in a debug engine module that resides in a memory of the KB-BIOS, and to send debug data associated with the development notebook computing system to the host computer via the serial PS/2 port in response to execution of the debug command. In this way, KB-BIOS debugging of the development notebook computing system can proceed without assistance from system BIOS of the development notebook computing system.
