W6-LI System Board Manual 13
Chapter 2: Configuring the W6-LI
Jumper Settings
This chapter gives you the jumper settings used for the W6-LI system
board.
Table 2-1 lists the jumper settings to select the CPU frequency. These
settings apply to both CPUs.
NOTE: Before making your selection, verify that
jumper W12 is closed.
Table 2-2 lists the jumper settings for the CPU Voltage Identification
(VID). The power regulators on the system board (one for each CPU) are
capable of generating different voltages. VID is a hardware mechanism
used by each CPU to tell its power regulator what voltage to set.
NOTE: If the CPU supports VID, all jumpers on W1 and/or W2 must be
removed or damage may occur. W1 is for the Primary CPU and W2 is for
the secondary CPU.
