CPU TYPE
2.2.1 INTEL PENTIUM CPU
The pentium processors have different operation voltage. In order to using the CPU
Voltage correctly, the following is the marking for identify the CPU type.
Description :
X = Voltage Specification (S or V)
S = Standard Voltage (3.4V)
V = VRE 3.4 - 3.6V (3.5V)
Z = Dual Processing Support ( S or U)
S = Support DP/MP/UP
U = Not tested to support DP
JUMPER SETTINGS
Pins 1 and 2 are shorted with a jumper cap.
Pins 2 and 3 are shorted with a jumper cap.
The jumper is shorted when the jumper cap is placed
over the two pins of the jumper.
The jumper is open when the jumper cap is removed
from jumper.
