Abstract: A data processing system comprises a processing core to execute a basic input/output system (BIOS) as part of a boot process. The data processing system also comprises static random-access memory (SRAM) in communication with the processing core. The data processing system also comprises a pre-BIOS component in communication with the SRAM. The pre-BIOS component is configured to execute a pre-BIOS block before the processing core begins executing the BIOS. The pre-BIOS block, when executed by the pre-BIOS component, causes the pre-BIOS component to (a) initialize the pre-BIOS component, (b) measure an amount of time taken to initialize the pre-BIOS component, and (c) save the measured amount of time to the SRAM as a pre-BIOS boot-time record. Other embodiments are described and claimed.
