Before the CPU is installed, the mainboard must be placed on a flat
plane in order to avoid being broken by the pressure of CPU installation.
3.7. 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 10 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.
3.8. SPEAKER CONNECTOR INSTALLATION
There is always a speaker in AT system for sound purpose. The 4 - Pins
connector
JP20
is used to connect speaker. The speaker can work well in both
direction of connector when it is installed to the connector
JP20
on mainboard.
3.9. POWER LED & KEY LOCK CONNECTOR INSTALLATION
There are a system power LED lamp and a key on the panel of case. The power
LED will light on when system is powered-on, and the key can lock the keyboard
input or unlock it, both of them are connected to a 5 PIN connector. The
connector should be installed to
JP17
of mainboard in correct direction.
3.10. TURBO SWITCH CONNECTOR INSTALLATION
The TURBO switch on the panel is used for controlling the system speed. Some
