  • Page 81: Power-On Self-Test (Post)

    Power-On Self-Test (POST) Before the computer can be used, all the components must be tested and initialized, and the operating system must be bootstrapped into memory. This process is know as the power-on Self test(POST), generally under the control of the BIOS. The Power-On Self Test (POST) is a BIOS procedure that boots the system, initializes and diagnoses the system components, and controls the operation of the power-on password option.

  • Page 82: Post Check Points

    When POST executes a task, it uses a series of preset numbers called check point to be latched at port 80h, indicating the stages it is currently running. This latch can be read and shown on a debug board. The following table describes the Acer common tasks carried out by POST. A unique check point number represents each task.
