Preface
About This Manual
This manual is written for system houses, PC technicians and
knowledgeable PC end users. It provides information for the instal-
lation and use of SUPER P6DLS/P6DLE/P6SLS/P6SLA
motherboard. SUPER P6DLS/P6DLE/P6SLS/P6SLA supports
Pentium II 300/266/233 MHz.
The Pentium II processor with the Dual Independent Bus Architec-
ture is housed in a new package technology called the Single Edge
Contact (S.E.C.) cartridge. This new cartridge package and its as-
sociated "Slot 1" infrastructure will provide the headroom for future
high-performance processors.
Manual Organization
Chapter 1, Introduction, describes the features, specifications and
performance of the SUPER P6DLS/P6DLE/P6SLS/P6SLA system
board, provides detailed information about the chipset, and offers
warranty information.
Refer to Chapter 2, Installation, for instructions on how to install the
Pentium II processor, the retention mechanism, and the heat sink
support. This chapter provides you with the instructions for han-
dling static-sensitive devices. Read this chapter when you want to
install or remove DIMM memory modules and to mount the system
board in the chassis. Also refer to this chapter to connect the floppy
and hard disk drives, IDE interfaces, parallel port, serial ports, as
well as the cables for the power supply, reset cable, Keylock/Power
LED, speaker and keyboard.

If you encounter any problem, please see Chapter 3, Troubleshoot-
ing, which describes troubleshooting procedures for video, memo-
ry, and the setup configuration stored in memory. Instructions are
also included on contacting a technical assistance support repre-
sentative and returning merchandise for service and the BBS# for
BIOS upgrades.

Introduction
1-1 Overview
SUPER P6DLS/P6DLE supports dual Pentium II 300/266/233 MHz
or higher processors. SUPER P6SLS/P6SLA supports single
Pentium II. They are based on Intel’s 440 LX chipset which enables
Accelerated Graphics Port (AGP), Wake-on-LAN, SDRAM, concur-
rent PCI and Ultra DMA 33 MB/s burst data transfer rate.
All motherboards are ATX size and have 4 PCI slots, 3 ISA slots and
an AGP connector. SUPER P6DLS, P6DLE and P6SLS accommo-
date a total of 1 GB EDO or 512 MB SDRAM memory with 4 168-pin
DIMM sockets. SUPER P6SLA accommodates a total of 768 MB
EDO or 384 MB SDRAM memory with 3 168-pin DIMM sockets.
AGP reduces contention with the CPU and I/O devices by broaden-
ing the bandwidth of graphics to memory. It delivers a maximum of
532 MB/s 2x transfer mode which is quadruple the PCI speed!
Wake on LAN allows remote network management and configura-
tion of the PC, even in off-hours when the PC is turned off. This
reduces the complexity of managing the network.
Other features that maximize customer satisfaction and simplicity in
managing the computer are PC 98-ready and support for Advanced
Configuration and Power Interface (ACPI). With PC Health Monitor-
ing, you can protect your system from problems before they even
occur.
Included I/O on all motherboards are 2 EIDE ports, a floppy port, an
ECP/EPP parallel port, PS/2 mouse and PS/2 keyboard, 2 serial
ports, an infrared port and 2 USB ports. SUPER P6DLS and P6SLS
provide an on-board Adaptec 2940UW Ultra Wide SCSI controller
with fast data transfer rate of up to 40 MB/s.
