Abstract

See full text

An electronic device includes routing logic operatively coupled to a communication port that is externally accessible so that there is no need to disassemble the electronic device to gain access. The port may be a USB (universal serial bus) port and provides access to an internal bus. The routing logic is also operatively coupled to a memory subsystem such that it may route data from an external device, connected at the port, to the memory subsystem to modify or replace a boot code, including a BIOS code. A memory interface device includes an interface module, a memory interface module for communicating with a memory subsystem including a boot PROM (programmable read only memory), and a routing logic coupled to the interface module and the memory interface module. The routing logic routes data from the external device to the boot PROM, so that a boot code, including a BIOS (basic input/output system), may be modified or replaced.
