This option can speed up the boot process by bypassing some compatibility steps:
• Minimal — The system boots quickly, unless the BIOS has been updated, memory changed, or
the previous POST did not complete.
• Thorough — The system does not skip any steps in the boot process.
• Auto — This allows the operating system to control this setting (this works only when the
operating system supports Simple Boot Flag).
