Preface
About This Manual
This manual is written for system houses, PC technicians and
knowledgeable PC end users. It provides information for the installation and
use of SUPER P6DBS/P6DBE/P6DBU/P6SBU/P6SBS/P6SBA motherboard.
SUPER P6DBS/P6DBE/P6DBU/P6SBU/P6SBS/P6SBA supports Pentium II
400/350/333/300/266/233 MHz.
The Pentium II processor with the Dual Independent Bus Architecture is
housed in a new package technology called the Single Edge Contact (S.E.C.)
cartridge. This new cartridge package and its associated "Slot 1" infrastruc-
ture will provide the headroom for future high-performance processors.
Manual Organization
Chapter 1, Introduction, describes the features, specifications and perfor-
mance of the SUPER P6DBS/P6DBE/P6DBU/P6SBU/P6SBS/P6SBA 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 chap-
ter provides you with the instructions for handling static-sensitive devices.
Read this chapter when you want to install DIM 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, Troubleshooting, which
describes troubleshooting procedures for video, memory, and the setup con-
figuration stored in memory. For quick reference, a general FAQ [frequently
asked questions] is provided. Instructions are also included for technical

Introduction
1-1 Overview
SUPER P6DBS/P6DBE/P6DBU/P6SBU/P6SBS/P6SBA supports Pentium II 233/
266/300/333 MHz processors and *Celeron 266/300 or higher at 66MHz bus
speed or Pentium II 350/400 MHz processors at 100MHz bus speed. SUPER
P6DBU, P6DBS, and P6DBE supports dual Pentium II processors. SUPER
P6SBU/P6SBS/P6SBA supports a single Pentium II processor. All six
motherboards are based on Intel’s 440BX chipset which enables 66/100
MHz system bus speed, Accelerated Graphics Port (AGP), Wake-on-LAN,
SDRAM, concurrent PCI and Ultra DMA 33 MB/s burst data transfer rate.
While all of the motherboards are ATX form factor, P6DBU and P6DBE have
5 PCI and 2 ISA with one shared slot. SUPER P6DBS, P6SBU, P6SBS and
P6SBA have 4 PCI and 3 ISA with one shared slot. All six motherboards
have the AGP port, and can accommodate a total of 1 GB EDO at 66 MHz or
512 MB unbuffered SDRAM or 1 GB registered SDRAM memory with 4 168-
pin DIMM sockets.
AGP reduces contention with the CPU and I/O devices by broadening 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 configuration of the
PC, even in off-hours when the PC is turned off. This reduces the com-
plexity of managing the network.
Other features that maximize customer satisfaction and simplicity in manag-
ing the computer are PC 98-ready and support for Advanced Configuration
and Power Interface (ACPI). With PC Health Monitoring, 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, a PS/2 mouse and PS/2 keyboard, 2 serial ports, an infrared
port and 2 USB ports. SUPER P6DBUand P6SBU provide on-board Adaptec
7890 Ultra II SCSI controller with data transfer rate of up to 80 MB/s, and
optional RAID III (ARO-1130CX). SUPER P6DBS and P6SBS have integrated
*Note: Celeron is single processor only

SUPER P6DBS/P6DBE/P6DBU/P6SBU/P6SBS/P6SBA Manual

on-board Adaptec 7895 MultiChannel UW SCSI controller. The dual chan-
nels allow data transfer rate of 40 MB/s per channel. Additionally, these
two motherboards have a RAID port on-board to support the Adaptec ARO-
1130SA/CA RAIDport II card for increase I/O performance and fault toler-
ance.
