Quick Start Guide
Step 3. Configure Memory
Your board comes with four DIMM sockets, providing support for up to 1GB of main memory
using DIMM modules from 8MB to 256MB. For 66MHz front side bus CPUs use 12ns or faster
memory; for 100MHz front side bus CPUs use 8ns (100MHz, PC100 compliant) memory.

Size (MB)
8/16/32/64/128/256 Mbytes
Notice 1: 256 MB memory modules only available on PC registered DIMM.
Notice 2: Always install memory modules in the order prescribed in this table.
Notice 3: Do not install unbuffered and registered memory modules together.
Important:
It is of prime importance that you install DIMM modules as outlined in the table
above in order to preserve signal integrity on 100MHz front side bus systems.
Step 4. Set the CPU Frequency
You do not need to set any jumper for the CPU frequency. Instead, CPU settings are
changed through the BIOS
[SOYO COMBO SETUP].
Please refer to Chapter 3 - Quick
BIOS Setup for details on how to set the Pentium
®
II processor frequency.
Step 5. Enable/Disable Power-On by PS/2 Keyboard (JP1)
You can choose to enable the Power-On by PS/2 Keyboard function by shorting pin 2-3 on
jumper JP1, otherwise, short pin 1-2 to disable this function.

Important: When using the Power-On by PS/2 Keyboard function, please make sure
the ATX power supply can take at least 720mA load on the 5V Standby lead (5VSB)
to meet the standard ATX specifications.
