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.

CPU	Bus	W4	W5	W6	W7	W8	W9
Speed	Speed
150 MHz	60 x 2.5	Close	Open	Close	Close	Close	Open
166 MHz	66 x 2.5	Open	Close	Close	Close	Close	Open
180 MHz	60 x 3.0	Close	Open	Close	Close	Open	Close
200 MHz	66 x 3.0	Open	Close	Close	Close	Open	Close

Table 2-1: CPU Speed Selections

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.

CPU Voltage		Jumpers
		W1 and W2
	1-2	3-4	5-6	7-8
VID-Enabled (default)	Open	Open	Open	Open
Non-VID 2.9V	Close	Open	Open	Close
Non-VID 3.1V	Close	Open	Close	Close
Non-VID 3.3V	Close	Close	Open	Close
