Abstract
A computing device configuration modification prevention system includes a chassis that houses a BIOS storage subsystem that stores a BIOS authentication information and BIOS settings, a BIOS settings modification subsystem and a BIOS authentication modification subsystem, and a BIOS lockdown subsystem that is coupled to the BIOS storage subsystem, the BIOS settings modification subsystem, and the BIOS authentication modification subsystem. The BIOS lockdown subsystem determines that a BIOS lockdown mode is set and configures the BIOS storage subsystem to prevent modification of the BIOS settings. The BIOS lockdown subsystem then executes first BIOS instructions to provide a BIOS while ignoring a subset of the first BIOS instructions to access the BIOS settings modification subsystem, and executes second BIOS instructions to provide the BIOS while ignoring a subset of the second BIOS instructions to access the BIOS authentication modification subsystem.
