Power-On Self-Test (POST)
When you turn on the system, it performs a series of tests to check
the operation of the system and some options. This series of tests is
called the power-on self-test, or POST.
POST does the following:
Checks some basic system-board operations
Checks the memory operation
Compares the current system configuration with the stored
system configuration information
Starts the video operation
Verifies that drives (such as the diskette, CD-ROM, and hard
disk drives) are working
While the memory is being tested, the amount of available memory
and appears on the screen. These numbers advance as the system
progresses through POST. If POST finishes without detecting any
problems, a single beep sounds and the first screen of your
operating system or application program appears.
