The Power-On Self Test (POST)

Each time you turn on the computer, the system takes a few seconds to conduct a
POST, including a quick test of the on-board RAM (memory).
As the POST proceeds, the computer will tell you if there is anything wrong. If there is a
problem that prevents the system from booting, it will display a system summary and
prompt you to run Setup.
If there are no problems, the Setup prompt will disappear and the system will load the
operating system. Once that starts, you can't get into Setup without rebooting.
