US 2007/0168763 A1 · System and method for auxiliary channel error messaging

Abstract

Information handling system errors are presented at a display with the information handling system graphics subsystem inoperative by communicating an identified error to the display through an auxiliary channel and generating a presentation of the error information with a microcontroller of the display. For example, errors determined by BIOS firmware running on a chipset are communicated through a DDC or I2C channel from the chipset to the display so that textual error messages are generated at the display without the use of the information handling system's graphic processor to generate an error message image.

Dependent claims

An information handling system comprising:

plural processing components operable to generate visual information for presentation at a display;
a display operable to present the visual information;
an interface operable to communicate information between the processing components and the display;
a microcontroller disposed in the display and operable to communicate management information from the display to the processing components through an auxiliary channel of the interface;
an error engine running on one or more of the processing components and operable to identify errors associated with one or more of the processing components and to communicate the errors to the display through the auxiliary channel;
and
an error reporter running on the microcontroller and interfaced with the error engine through the auxiliary channel, the error reporter operable to present the errors at the display.
