Chapter 2: Installation
Internal Buzzer (SPEAKER)
The Internal Buzzer (SPEAKER) is used to provide audible indications for various beep codes. See the table on the right for pin definitions.
Speaker (JSPK)
On the JSPK header, Pins 3~4 are used for the internal speaker. Close Pins 3~4 with a jumper or cap to use the onboard speaker. If you wish to use an external speaker, remove the jumper and attach the external speaker's cable to Pins 1~4. See the table on the right for pin definitions.
Internal Battery (BAT)
The Internal Battery (BAT) is used to provide battery backup to the CMOS, so the motherboard does not lose its configuration when the system is off.
