Dual Voltage CPU Setting
Dual voltage CPUs are designed to use different voltage for VIO and
VCore and they include Intel P55C series, Cyrix 6x86L/MX, AMD K6,
and MMX technology included CPUs.  Refer to the following figures to
set these CPUsÕ voltage:

Note:
Due to various design, please ask your CPU dealer for the exact
VIO and VCORE voltage before you install it.
Memory Configuration
The mainboard supports two banks of 72-pin SIMM modules and three
strips of 168-pin/3.3V Unbuffered DIMM modules.
  The mainboard
requires SIMM of at least 70ns access time.
The mainboard supports from 4 to 256 Mbytes with no other restrictions
on memory configurations.  You must install two strips of SIMM
modules to complete a bank.
