Power-on self-test data notification

A method of providing POST data associated with a POST executing on a target computer system, comprising:

• storing POST data corresponding to a POST event in at least one hardware register;
• transferring the POST data from the at least one hardware register to a target system port of the target computer system wherein the at least one hardware register provides the POST data to an external output device without using the target computer system memory;
• receiving the POST data at the external output device from the target system port via a data cable comprising a USB cable connecting the output device to the target computer system;
• generating a notification corresponding to the POST data by a POST data notification application executing on the external output device and connected to the target system port of the target computer system via the USB cable, and
• display the notification on a display of the external output device.

A system for providing POST data associated with a POST executing on a target computer system, comprising:

• a POST data transport module comprising an interface for a debug module within a firmware of a target computer system, the POST data transport module operative to
• receive the POST data corresponding to a POST event, and
• write the POST data to at least one hardware register associated with a target system port configured for connection to an external output device via a data cable, wherein the at least one hardware register provides the POST data to an external output device without using the target computer system memory;
• and
• a POST data notification application capable of executing on an external output device connected to the target system port of the target computer system via the data cable, wherein the POST data notification application operative to
• receive the POST data from the data cable connecting the external output device to the target computer system,
• generate a notification corresponding to the POST data, and
• display the notification on a display of the external output device.
