M
We don' t recommend you to setup your system speed to 75or 83MHz
because these frequencies are not the standard specifications for
CPU, Chipset and most of the peripherals. Whether your system can
run under 75 or 83MHz properly will depend on your hardware
configurations: CPU, SDRAM, Cards, etc.
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.
M Replace only with the same or equivalent type recommended by the
manufacturer.
M Dispose of used batteries according to the manufacturer' s instructions.
