Hardware Setup
jumpers, the settings for the CPU frequency are set through the BIOS
Setup which allows you to use any type of CPU from the Pentium II
familyÕs 233 ~ 550 range.
In order to change the CPU type, you need to enter the BIOS by pressing
the <Delete> key during boot-up and then select the ÒChipset Features
SetupÓ menu. There is an item called ÒCPU SpeedÓ under this setup
section and it allows you to set the frequency according to the speed of
the Pentium II CPU that you have, which should be clearly indicated on
the outer cover. The choices of settings are 133, 233, 266, 300, 333, 350,
400, 450, 500, and 550 MHz. Notice that the fastest CPU available was
400MHz at the time of this board was released, therefore we can
guarantee proper functioning only up to 400 MHz. The 133 and 200
MHz settings are used as default and as a ÒsafeÓ frequency, which means
that the board can be boot-up at any time even if the BIOS settings are
erased or reset, there is however no Pentium II CPU of those frequencies.
The 133MHz value is used for CPUs with a 66MHz Bus Clock, and the
200 MHz value is used for CPUs with a 100MHz Bus Clock. The BIOS
will automatically detect the Bus Clock of your CPU.
If the frequency is set too high, the CPU will not be able to function
properly and the board will not boot up. By pressing the <Insert> key a
few times while turning on the computer, the frequency will be set back
to the default value and you will be able to enter the BIOS Setup to
correct the CPU frequency value.
Memory Configuration
The mainboard supports four banks of
168-pin 3.3V SDRM Unbuffered
DIMM
. The mainboard supports
from 8 to 384 Mbytes
with no other
restrictions on memory configurations. Use 12ns or faster DIMM
modules for 66MHz and use 8ns modules for 100MHz host bus CPUs.

Note: It is very important that you install DIMM modules as outlined in
the table above in order to preserve the signal integrity on
100MHz host bus systems.
