3.6. CMOS RTC & ISA CFG CMOS SRAM

There're RTC & CMOS SRAM on board, they have a power supply from

internal battery to keep the DATA inviolate & effective. The RTC is a REAL-

TIME CLOCK device which provides the DATE & TIME to system.

The CMOS SRAM is used for keeping the information of ISA device system

configuration, so the system can automatically boot OS. every time.

Due to the life-time of RTC internal battery is 5 years, the user can change a

new RTC to replace old one after it can not work. The new one's brand and

type must be same with old one.

There is always a speaker in AT system for sound purpose. The 4 - Pins

connector J3 is used to connect speaker.

The speaker can work well in both direction of connector when it is installed

to the connector J3 on mainboard.

The RESET switch on panel provides users with HARDWARE RESET

function which is almost the same as power-on/off.

The system will do a cold start after

the RESET switch is pushed and

released by user. The RESET switch is a 2 PIN connector and should be

installed to J4 on mainboard.

There are a system power LED lamp on the panel of case. The power LED

will light on when system is powered-on, which is connected to a 3 PIN

connector.

The connector should be connected to J5 of mainboard in correct direction.

The J8 is a indicator (green LED) for green function. If the green LED is ON,

the system is operating in green mode.
