Error Messages
Your computer’s built-in memory (ROM) contains a series of
diagnostics programs, called power-on diagnostics, which your
computer runs automatically every time you turn it on. These
programs check internal devices such as ROM, RAM, the timer,
the keyboard controller, and the hard disk drive. The RAM test
program displays the total amount of memory currently installed
in your system. If the computer finds an error, it displays an error
message on the screen.
