Conducting preliminary POST diagnostics. 2. Initializing the operating system. 3. Initializing hardware. 4. Running diagnostic tests on several functions, including circuitry, port functionality, memory, statistics counters, and serialization. BOOT Boot completes in a minimum of three minutes if POST is run. In addition to POST, boot includes the following tasks after POST is complete: 1. Performing universal port configuration. 2.
