Abstract

The system architecture of the present invention programs a permanent version of firmware in ROM and employs a validation scheme for downloaded firmware. The downloaded firmware is executed when the validation scheme successfully validates the firmware. In the event that the downloaded firmware fails to download successfully or bring up the system, the processor is able to complete the booting process using the permanent or most recently validated version of firmware.
