POST Diagnostics
POST is a firmware program that is useful in determining if a portion of the system
has failed. POST verifies the core functionality of the system, including the CPU
module(s), motherboard, memory, and some on-board I/O devices, and generates
messages that can be useful in determining the nature of a hardware failure. POST
can be run even if the system is unable to boot.
