3.3 CMOS RTC

CMOS RTC includes an internal battery and Real Time Clock circuit. It provides the date and the time for the system. Normally the life span of a RTC internal battery is 10 years. When replacing, you should use the same model.

3.4 Speaker Connector Installation

S1471 provides a 4-Pin header (J42) to connect the speaker. The polarity can go either way.

3.5 Turbo Switch

The front panel on your case may have a turbo switch to control system speed when slower program execution is required for software developed in the old XT days.

You can connect the chassis turbo switch to J49 on the mainboard. The 430VX chipset doesn't support a hardware turbo function so this switch will only turn on or off the turbo LED.

3.6 Turbo LED Connector Installation

The TURBO LED on the front case panel can indicate the current speed status of the system. The TURBO LED connector should be installed to J48 in the correct direction.
