Abstract: A controller determines whether system boot code stored in a first non-volatile memory is compromised and non-recoverable. In response to determining that the system boot code is compromised and non-recoverable, switch logic is activated to connect a second non-volatile memory to the shared bus and to disconnect the first non-volatile memory from the shared bus.
