3.7. CMOS RTC & ISA CFG CMOS SRAM

Built-in Real Time Clock (RTC) With 256B CMOS SRAM in M5819.

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

is used to connect speaker. The speaker can work well in both direction of

connector when it is installed to the connector SPK on mainboard.

This mainboard uses the existing power LED as ACPI LED .The ACPI LED will

light on when system is power-on .The ACPI LED is off when the system is power-

off. The ACPI LED will blink when system is in Green mode.This connector should

be installed to ACPI LED jumper of the mainboard in correct direction.

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 RES on mainboard.

There is one jumper for the purpose of power saving, GN, to indicate the power

saving function . This mainboard uses the existing power LED as ACPI LED . If the

ACPI LED is blinking, the system is in green mode. The GN switch will force the

system into green mode .

After installation of the device and setup of the jumpers, the mainboard can be

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

the peripheral devices could be installed now. The basic system needs a display

interface card and a storage device.

If a PCI - Bus device is to be installed in the system, any one of three PCI - Bus

slots can be used for Slave or Master PCI - Bus device.

After installing the peripheral device, the user should check everything again and

prepare to power-on the system.
