2. The system begins the Power On Self Test (POST). This test verifies that the
system memory, system board, video controller, floppy disk drive, hard disk drive,
drive controllers, and peripheral devices are all operational. The system emits one
short beep to indicate that it has passed the POST.
Note: If the POST detects an error, it displays an error message on the monitor.
Also, it may emit a corresponding beep code, an error message consisting
of speaker tones arranged in distinctive patterns. For information on
what to do for POST errors, see “Solving Workstation Problems,” later
in this section.
3. As the POST executes, it displays system settings and values (such as processor
type and speed, memory size, and so forth). Verify that these values match your

6. If you have a properly configured hard disk drive with a boot partition that
contains operating system software, the operating system load messages appear on
the monitor.
Note: If the operating system is not yet installed or the system configuration in
CMOS memory is not correct, the system does not issue load messages.
When a system experiences problems during startup, it either halts the sequence or
generates an error message to indicate that a failure has occurred. The following
paragraphs discuss some of the actions you can take to resolve an installation problem.
