Abstract
An information handling system includes a memory to store BIOS, a processor, a BMC, and an add-in device. The BMC updates the BIOS in a first system state and prevents BIOS updates in a second system state. The add-in device is configured to update firmware in a first device state and to prevent firmware updates in a second device state. The add-in device enters the first device state when the add-in device receives a power-on reset. The add-in device receives a lockdown command, sets the add-in device to the second device state in response to the lockdown command, and prevents the add-in device from reentering the first device state until the add-in device receives a second power-on reset subsequent to the first power-on reset.
