M
We don’ t recommend you to setup your system speed to 75, 95, 112,
124 or 133MHz because these frequencies are not the standard
specifications for CPU, Chipset and most of the peripherals. Whether
your system can run under 75, 95, 112, 124 or 133MHz properly will
depend on your hardware configurations: CPU, SDRAM, Cards, etc.
F
JP3 (SDRAM) Set 1-2 short
à
depends on CPU frequency.
F
JP3 (SDRAM) Set 2-3 short
à
depends on AGP frequency.
M
The CPU BUS Frequency is set at 66 MHz and 100MHz by CPU
default.
M
The CPU is a sensitive electric component and it can be easily
damaged by static electricity, so users must keep it away from metal
surface when the CPU is installed onto main board.
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.
M
Danger of explosion if battery is incorrectly replaced.
