A secure multi-Basic Input/Output System (BIOS)-image system includes a BIOS storage system having a first BIOS storage region and a second BIOS storage region. A first BIOS image is stored in the first BIOS storage region and is configured to utilize a plurality of initialization drivers during a first initialization process. A BIOS subsystem is coupled to the BIOS storage system. The BIOS subsystem receives second BIOS storage region write-enablement information and, in response, enables writing to the second BIOS storage region. Subsequent to enabling writing to the second BIOS storage region, the BIOS subsystem writes a second BIOS image to the second BIOS storage region. The BIOS subsystem may then use the second BIOS image that was written to the second BIOS storage region to perform a second initialization process that utilizes a subset of the plurality of initialization drivers.
