III. INSTALLATION
Single/Dual Power Plane CPU Voltage Regulator Selections (JP1, 20)
The following jumpers set the voltage supplied to the CPU. Determine whether
your CPU has a Single Power Plane or Dual Power Planes and then the volt-
age that it uses. When a single power plane CPU is installed, the dual power
plane selections will be automatically disabled. When a dual power plane CPU
is installed, the single power plane selections will be automatically disabled.
You may have one jumper on the Single Power Plane and another on the Dual
Power Planes at the same time.
WARNING: Incorrect setting can damage your CPU. If you are not
exactly clear on CPU jumper settings, check with your retailer.
