Configuration of Jumpers
Jumpers are small plastic-encased conductors that are used to slip over a pair of
jumper pins. We designs all mainboards with the fewest jumpers and pins to make
your setup fast and easy. It is recommended that the jumpers be set before the
mainboard is installed into the case because access to the jumpers will be easier.
The following will describe all of the jumpers that are required to be set before
moving on.
Note: The jumpers as shown below are in their correct physical orientation.
CMOS Clear
JP1 : = 1-2 - Normal (Default)
= 2-3 - Clear CMOS
Keyboard Power-ON function (see page 31)
JP13 : = 1-2 - Enable
= 2-3 - Disable (Default)
Based on the implementation of the VIA Apollo Pro133A AGPset the board
provides 66, 100, or 133MHz for FC-PGA processors and memory operations.
The primary and secondary processor slots both operate synchronously, therefore
if two processors are used both will need to be of the same type and speed. When
using the 100MHz FSB all memory must be PC100 or PC133 compliant SDRAM.
133MHz FSB requires PC133 compliant SDRAM at all times.
Memory is an important component of any motherboard. When selecting memory
for use on your motherboard we recommend using only the finest quality modules.
We would like to stress that using non-compliant SDRAM modules with a 100 or
133MHz FSB severely compromises the integrity of the system.
NOTE: Not all FC-PGA Intel Pentium III processors support dual CPU
operation. Please refer to processor documentation or Intel’s website for more
information. http://www.intel.com
CPU Speed Selection
JP3 : = 1-2 - 66MHz FSB
= 2-3 - 100/133MHz FSB (Default)
(133MHz FSB if supported by CPU will automati-
cally be selected. Jumper will be ignored.)
