congure the way to turn off your system using the power switch (refer to
Chapter 2, "BIOS Setup," "Power Management," for more information).
• SPEAK (Speaker, Orange):
Connects to the speaker on the chassis front panel. The system reports
system startup status by issuing a beep code. One single short beep
will be heard if no problem is detected at system startup. If a problem
is detected, the BIOS may issue beeps in different patterns to indicate
the problem.
