ABSTRACT:
The original firmware of a computing device is stored in a fixed non-volatile ROM-type memory while any subsequently issued replacement firmware correcting or upgrading erroneous firmware contained within the original firmware is stored in a reprogrammable EEPROM-type non-volatile memory. The locations in the fixed and reprogrammable memories storing the corresponding erroneous and replacement firmware, respectively, are identified in a data table that is also stored in the reprogrammable memory. A field programmable gate array connected to the reprogrammable memory uses the data table to identify computing device requests to the fixed memory for erroneous firmware and in response thereto inhibit output of erroneous firmware. The gate array further uses the data table to access the reprogrammable memory and output corresponding replacement firmware in substitution for the device requested original, but erroneous, firmware.
