1. All default jumper settings are based on
Intel Celeron CPU 366 MHz together
with SDRAM module that should meet
PC-100 specifications.
2. Always insert the SDRAM card into
DIMM1 slot first and then into DIMM2
or DIMM3.
3. "LOAD BEST DEFAULTS"
in CMOS setup menu loads the system
best default data directly from the
flash ROM and initializes the
associated hardware properly. This is
the default setting for the mainboard.
Quick CPU and SDRAM Clock Frequency Selection
In BIOS Setup, the CPU Host/SDRAM Clock item of Chipset Features Setup Menu
can set CPU and SDRAM combined clock frequencies. The choices are 133/133,
124/124, 112/112, 100/100, 105/105, 90/90, 95/95, 83/83, 75/75, 66/66, 83/55, 95/63,
66/100, 112/74, 124/82 and Default (66/66).
The BIOS has also been enhanced that it will intelligently judge the CPU Clock
Frequency you selected in BIOS Setup. If the selected CPU clock is not acceptable,
the system will hang up with black screen after exiting BIOS Setup. When reboot the
machine, the following messages will be shown on screen after finishing POST:
"Your previous attempt for setting CPU/SDRAM combined clock has
caused system hanging up. This rebooting has restored the CPU/SDRAM
to a 66/66 combination. Please press DEL key to re-enter BIOS SETUP or
any other key to accept the default."
At this point, press "DEL" key to re-enter BIOS Setup to select
another CPU/SDRAM combination values or any other key to accept
the default.

4. If you experience power on
problem with wrong CMOS
settings, turn on your computer
with INSERT key being pressed,
this will force the POST (Power
On Self Test) run with default
CMOS settings. By this way, you
will be able to enter into CMOS
setup to correct your settings.
5. There is a basic requirement
that the" +5V SB" power of the
ATX power supply must be > =
0.2A (200mA) for KBPO
(KeyBoard Power On) to
operate correctly.
