POST CODE REPORTING VIA SECURE DIGITAL MEMORY INTERFACE

Abstract:

Device and method for reporting power-on self-test (POST) codes of a computing device via a standard external memory card interface. A BIOS of the personal computing device is programmed to configure, during a power-on sequence, multiple signal connections of the standard external memory card interface for conveyance of general purpose input and output signals. When a complementary memory signal conversion device is detected in the memory card interface during the power-on sequence, the BIOS may initiate transmission of a serial data signal containing POST codes related to any detected startup errors.
