Abstract:
In one aspect, the present invention relates to a system memory device for a computer system having a processor and a firmware. In one embodiment, the system memory device has a RAM, and a ROM with stored boot block data and operational code data, the boot block data containing computer-executable instructions for initializing the firmware, determining if the operational code data is valid, and if the operational code data is valid, copying the operational code data from the ROM to the RAM, where the operational code data contains computer-executable instructions for enabling a plurality of different interfaces to receive a firmware update from a firmware update provider, and if the operational code data is not valid, causing a particular one of the plurality of enabled interfaces to wait for an available firmware update and, when a firmware update is available, receiving the firmware update.
