POWER-ON SELF-TEST (POST)
Each time the system is powered on, the system checks the working status of components
through an automatic power-on self-test (POST). The test checks the system configuration
for any discrepancies. One beep means that POST is successful. If any problems in data
transfer or hardware exist, an error message appears.

Enter
to review the settings, and make any necessary corrections. For more complete information,
