3.6. CMOS RTC & ISA CFG CMOS SRAM

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

external 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 system configuration, so

the system can automatically boot OS every time. Since the lifetime of

internal battery is 5 years, the user can change a new Battery to replace old

one after it cannot work.

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

SPKR is used to connect speaker. Anode connects +, Cathode connects .

Pin2-3 short is internal speaker(Default value).

The RESET switch on panel provides users with HARDWARE RESET

function. 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 RE on mainboard.

System has power LED lamp on the panel of case. The power LED will light

on off or flash to indicate which step on the system. The connector should be

connected to PWR of mainboard in correct direction.

3.10. IDE & ATAPI DEVICE INSTALLATION

There are two-Enhanced PCI IDE ports (IDE1, IDE2) on board, which

following ATAPI standard SPEC. Any one IDE port can connected to two

ATAPI devices (IDE Hard Disk, CD-ROM & Tape Driver), so total four ATAPI

devices can exist in a system. The HD is the active LED port for ATAPI

devices.

After the I/O device installation and jumpers setup, the mainboard can be

mounted into the case and fixed by screw. To complete the mainboard

installation, the peripheral device could be installed now. The basic system

needs a display interface card. If the PCI - Bus device is to be installed in the

system, any one of four PCI - Bus slots can be used.
