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 P6DLH/P6DLF motherboard. SUPER
P6DLH/P6DLF supports Pentium II 233/266/300/333 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 P6DLH/P6DLF system board, provides
detailed information about the chipset, and offers warranty informa-
tion.
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 SIMM/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 P6DLH and P6DLF support dual PentiumII 233/266/300/
333 MHz processors. They are based on Intel’s 440 LX chipset
which enables Accelerated Graphics Port (AGP), Wake-on-LAN,
SDRAM, concurrent PCI, and Ultra DMA 33 MB/s burst data transfer
rate. SUPER P6DLH is I2O-readyTM with a 66 MHz i960RD I/O
processor built-in. AGP is disabled on SUPER P6DLH.
Both motherboards are Full AT size (13.2" x 12.2"). SUPER P6DLF
provides 5 PCI slots, 3 ISA slots and an Accelerated Graphics Port.
It accommodates a total of 1 GB EDO or 512 MB SDRAM memory
with 8 72-pin SIMMs or 4 168-pin DIMM sockets.
SUPER P6DLH provides 9 PCI slots and 3 ISA slots. It accommo-
dates a total of 1 GB EDO or 512 MB SDRAM. The I2O architecture
of SUPER P6DLH consists of a 66 MHz i960 RD I/O processor, an 8
Mb Flash I/O BIOS, and local IOP memory of up to 64 MB. The I2O
architecture provides a standard way to off-load the I/O functions
from the CPU, creating a direct I/O pipeline that no longer passes
through the host processor. Besides delivering increased system
performance, the I2O specification eliminates the need for different
drivers for each combination of operating system and SCSI or Net-
work Interface Card. Because the drivers may be standardized, and
not re-written for new operating system releases, drivers can be-
come more highly optimized and robust, improving performance
and reliability in mission-critical enterprise computing.
To attain portability across multiple operating systems and host
platforms, I2O drivers are divided into the OS Services Module
(OSM), and Hardware Device Module (HDM). The first module inter-
faces with the host operating system. The second interfaces with
the particular device, media or server managed by the driver. The

1-2
SUPER P6DLH/P6DLF User’s Manual
two modules interface with each other through a two-layered com-
munications system. A Message Layer sets up a communications
session. A Transport Layer defines how information will be shared.
The Message Layer resides on the Transport Layer.
The i960 RD I/O processor (IU20) is a highly integrated intelligent I/
O subsystem on a chip. Mode 3 is the default setting for its normal
operation. The i960 RD has two main functions. As a local proces-
sor, it offloads interrupt-intensive I/O tasks from the host CPU. Its
architecture is composed of a RISC core surrounded by peripherals
essential to the I/O function. The on-board PCI-to-PCI bridge en-
ables designers to connect I/O components directly to the PCI bus
and also add additional PCI slots. The bridge improves overall
system performance by reducing bus traffic.
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 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.
Included I/O are 2 EIDE ports, a floppy port, an ECP/EPP parallel
port, a PS/2 mouse port, 2 serial ports, an infrared port and 2 USB
ports. The boards come with a CD with software utilities such as:
SUPERMICRO PIIX4 Upgrade Utility for Windows95, BIOS Flash
Upgrade Utility, DMI Browser for Windows 95, DMI Wizard,
SUPERMICRO SUPER Doctor Utility ver 1.20b, and Intel
LANDeskClient Manager for Windows NTand Windows 95 (op-
tional).
