Abstract: Technologies for improving platform initialization on a computing device include beginning initialization of a platform of the computing device using a basic input/output system (BIOS) of the computing device. A security co-processor driver module adds a security co-processor command to a command list when a security processor command is received from the BIOS module. The computing device establishes a periodic interrupt of the initialization of the platform to query the security co-processor regarding the availability of a response to a previously submitted security co-processor command, forward any responses received by the security co-processor driver module to the BIOS module, and submit the next security co-processor command in the command list to the security co-processor.
