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 the SUPER P6DBS/P6DBE/P6DBU/P6SBU/P6SBS/P6SBA/P6SBM
motherboard. The SUPER P6DBS/P6DBE/P6DBU/P6SBU/P6SBS/P6SBA/
P6SBM supports Pentium II 400/350/333/300/266/233 MHz processors.
The Pentium II processor with the Dual Independent Bus Architecture is
housed in a new package technology called the Single Edge Contact Cartridge
(S.E.C.C.) . 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/P6SBM
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 problems, please see Chapter 3, Troubleshooting, which
describes troubleshooting procedures for the video, memory, and the setup
configuration stored in memory. For quick reference, a general FAQ [Fre-
quently Asked Questions] section is provided. Instructions are also included

Introduction
1-1 Overview
The SUPER P6DBS/P6DBE/P6DBU/P6SBU/P6SBS/P6SBA/P6SBM supports
Pentium II 233/266/300/333 MHz and *Celeron 266/300 or higher processors at
a 66MHz bus speed or Pentium II 350/400 MHz processors at a 100MHz bus
speed. The SUPER P6DBU/P6DBS/P6DBE supports dual Pentium II proces-
sors, while the SUPER P6SBU/P6SBS/P6SBA/P6SBM supports a single
Pentium II processor. All seven 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, the P6DBU and P6DBE have
5 PCI and 2 ISA with one shared slot. The SUPER P6DBS, P6SBU, P6SBS and
P6SBA have 4 PCI and 3 ISA with one shared slot, and the SUPER P6SBM has
3 PCI and 1 ISA with one shared slot. All seven motherboards have the AGP port,
and all but the P6SBM 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. The SUPER P6SBM can accommodate 768 MB registered or 384 MB
unbuffered SDRAM.
AGP reduces contention with the CPU and I/O devices by broadening the band-
width 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 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 Monitoring, you can protect your system from
problems before they even occur.
*Note: Celeron is single processor only
** See bottom of page 2

SUPER P6DBS/P6DBE/P6DBU/P6SBU/P6SBS/P6SBA/P6SBM Manual
1-2
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. The SUPER P6DBU and P6SBU provide on-board Adaptec
7890 Ultra II SCSI controller with data transfer rate of up to 80 MB/s, and optional
RAIDport III (ARO-1130xA-2)**. The SUPER P6DBS and P6SBS have an inte-
grated on-board Adaptec 7895 MultiChannel UW SCSI controller. The dual chan-
nels allow a data transfer rate of 40 MB/s per channel. Additionally, these two
motherboards have a RAID port on-board to support the Adaptec ARO-1130xA
RAIDport II card** for increased I/O performance and fault tolerance.
**The x in 1130 xA and 1130 xA-2 refers to the RAIDport workstation driver (1130 CA) or server driver
(1130 SA) depending on software used. Please note: 1130 xA is compatible with NT Workstation, NT
Server and Netware Server. The 1130 xA-2 is only compatible with NT Workstation at this time. Check the
Adaptec web site for further information: www.adaptec.com.
