Abstract
An Information Handling System (IHS) includes multiple hardware devices, and a baseboard Management Controller (BMC) in communication with the plurality of hardware devices. The BMC includes instructions for executing a bootloader to verify an integrity of a first firmware stack, and boot the first firmware stack on a first processor. Once booted, the first firmware stack verifies the integrity of a first code segment on a second processor that is also used to execute a custom BMC firmware stack. The first code segment is executed to verify the integrity of one or more vendor supplied code segments executed on the second processor.
