IntroductionIntroduction
Overview
P6I440LX/DP Legend IV is a high-performance and powerful dual Pentium II
processor system, which provides on-board LAN for fast Ethernet network at
10/100Mbps, on-board Ultra Wide SCSI at 40MB/sec, RAID and health
system monitor support. Using the PCI/ISA architecture, the system provides a
highly integrated solution for fully compatible PC/AT platform, featuring the
industry standard ATX form factor. Flexible main memory size can be
installed from 8MB to 512MB SDRAM or 1GB EDO DIMM. The system also
offers a wide range of interface to support integrated on-board IDE and on-
board I/O functions. The system provides 3 modes of green function: Doze,
Standby and Suspend.

System Setting by Jumper
The mainboard offers a set of jumper settings to facilitate clock frequency
adjustment and some important selections.
CPU Frequency Selection
According to CPU’s specification, set CPUs clock speed carefully. The
following illustration lists the jumper settings for the PentiumII CPUs:
JP2 JP3 JP4 JP5
PentiumII 133MHz =2x66MHz
PentiumII 200MHz =3x66.66MHz
PentiumII 333MHZ=5x66MHZ
PentiumII 166=2.5x66MHZ

Warning::
Set CPU’s clock speed according to its specification.
CPU over speed will be dangerous!
