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 the SUPER™ P6DNF/P6SNF motherboard, which
supports the 200/180/166/150 and >200 MHz Intel®Pentium® Pro
processors.
The Pentium Pro processor has two 64-bit data buses. One bus
interconnects to the built-in L2 cache and the other is an external
bus that interconnects with the system memory, I/O and the other
processor. Both come with ECC (Error Checking and Correction)
allowing for the correction of single-bit data errors and detection of
2-bit errors on the data bus.
Manual Organization
Chapter 1, Introduction, describes the features, specifications and

detailed information about the chipset, and offers warranty informa-
tion.
Refer to Chapter 2, Installation, for a list of the equipment needed
for a system based on the SUPER P6DNF/P6SNF system board.
This chapter provides you with the instructions for handling static-
sensitive devices, checking and/or configuring the jumpers. Read
this chapter when you want to install or remove SIMM memory mod-
ules and to mount the system board in the chassis. Also refer to
this chapter to connect the floppy and hard disk drives, IDE inter-
face, 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 .

Chapter 1: Introduction
Chapter 1
Introduction
1-1 Overview
SUPER™ P6DNF/P6SNF is a high performance, function-enhanced
computer system board based on Intel®Pentium® Pro 200/180/166/
150 MHz processors. SUPER P6DNF/P6SNF incorporates Intel
440FX chipset. It supports dual processing (SUPER P6DNF) and
FPM or EDO memory of up to 1GB.
The Pentium Pro processor is Intel’s top-of-the-line generation of
performance for servers, workstations, and high-end desktops. It
delivers its superior performance through its Dynamic Execution
microarchitecture which allows multiple branch prediction, dataflow
analysis and speculative execution.
The Pentium Pro processor includes 16KB of internal cache and an
integrated 256KB or 512KB non-blocking secondary cache in the
same package. Having the L2 cache inside the package will not
only save space, it will also have the CPU core communicating with
the L2 cache at full speed. Non-blocking means that the transac-
tions on the processor bus do not block subsequent bus transac-
tions. For example, when a cache miss occurs, the processor will
continue to process other instructions while initiating a bus trans-
action to satisfy the cache miss. These instructions could generate
additional cache misses which could cause more bus transactions.
The Pentium Pro processor can maintain up to four concurrent re-
quests of the bus.
The general purpose registers of the Pentium Pro processor are
the same as on previous generations. The processor bus achieves
high bus efficiency by providing support for multiple, pipelined
transactions and deferred replies. A single processor may have up
to 4 outstanding transactions at the same time. There are a variety

1-2
SUPER P6DNF/P6SNF User’s Manual
of wider datapaths both inside and outside the chip. It has an
external 64-bit bus in order to communicate more efficiently with the
system memory. The package have two cavities with about 21 mil-
lion transistors. The larger one is the CPU core with 5.5 million
transistors. The smaller one is the non-blocking cache which con-
tains 15.5 million transistors.
Peripheral Component Interconnect (PCI) provides industry-leading
performance and compatibility. The 32-bit, 33 MHz pathway to the
CPU offers performance unmatched by other bus architectures. The
PCI standard is clearly defined to ensure complete compatibility. A
PCI add-on card available today will work in any PC-compliant sys-
tem in the future. The PCI add-on card interface is processor inde-
pendent. This will enable an efficient transition to future processor
generations and use with multiple processor architecture.
In addition to the security of a true standard, PCI add-on cards fea-
ture auto-configurability for easy integration. The user-friendly BIOS
automatically allocates system resources for add-on cards and con-
figures hard disk, memory, and other peripherals. No more
hassles with settings, jumpers, or switches. Just plug in the card
and go (Plug and Play or PnP).
The motherboard’s four 32-bit slots with industry standard PCI de-
sign have a very high performance capability that provides an ideal
system board solution for a wide range of demanding applications;
such as networking multiuser environments, computer aided
design (CAD), computer aided manufacturing (CAM), computer-
aided engineering (CAE), database management, desktop publish-
ing, image processing, and artificial intelligence. The
motherboard’s additional four ISA slots provide standard 16-bit
compatibility for AT-type add-on card expansion.

Chapter 1: Introduction
1-2 Power Supply
As with all computer products, a stable power source is necessary
for proper and reliable operation. It is even more important for high
CPU clock rates like 200, 180, 166, 150 MHz and future Pentium
Pro processors for the SUPER P6DNF/P6SNF system board.
The SUPER P6DNF/P6SNF can accomodate 5V power supplies.
Although most power supplies generally meet the specifications re-
quired by the CPU, some power supplies are not adequate. To
obtain the highest system reliability, be certain that your power sup-
ply provides +5 VDC with a voltage range between +4.95 VDC (mini-
mum) and +5.25 VDC (maximum).
It is highly recommended that you use a high quality power supply.
Additionally, in areas where noisy power transmission is present,
you may choose to install a line filter to separate noise from the
computer. You can also install a power surge protector to help
avoid problems caused by power surges.
1-3 Chipset Overview
The Intel 440FX chipset is a high-performance PCIset that supports
full symmetric multi-processor protocol for up to two processors. It
is compliant to the PCI Rev. 2.1 specification. The memory control-
ler provides capability for auto-detection of EDO/FPM DRAM type
installed in the system. It also provides data integrity features in-
cluding ECC in the memory array and parity error detection. Memory
is upgradable up to 1GB for the SUPER P6DNF/P6SNF.

1-10
SUPER P6DNF/P6SNF User’s Manual
1-4 National Semiconductor Super I/O Controller
The National Semiconductor 87306 Super I/O Controller incorpo-
rates an IDE control logic, two full function serial ports, an IEEE
1284 parallel port, industry standard floppy disk controller with 16
byte FIFO, Real Time Clock and an 8042 compatible keyboard con-
troller all in one chip.
The IDE interfaces provide up to Mode 4 support. The two serial
ports are software compatible with the Fast UART 16550. The par-
allel port is EPP (Enhanced Parallel Port) and ECP (Extended Ca-
pabilities Port) compatible, including level 2 support. It includes a
protection circuit against damage caused when the printer is pow-
ered up. EPP mode provides for greater throughput than Compat-
ible or Extended modes by supporting faster transfer rates and a
mechanism that allows the host to address peripheral device regis-
ters directly. Faster transfers are achieved by automatically gener-
ating the address and data strobes. EPP is compatible with both
Compatible and Extended mode parallel-port devices.
1-5 Voltage Regulator Modules (VRM)
The Voltage Regulator Module (VRM1 and VRM2) is a DC-to-DC
converter with a standardized interface to the system. The stan-
dardization allows a variety of Voltage Regulator Modules to support
the Pentium Pro processor family and to provide a cost effective
support for CPU upgrade.

Chapter 1: Introduction
1-6 System Overheat Thermal Control
A back-up cooling fan can be hooked up to JP91, JP92 or JP93. If
the power supply fan or the processor cooling fan goes down, the
circuitry will detect an overheat temperature depending on the user
setting. It will then trigger the backup cooling fan or alarm. The
alarm can be turned on or off using JP88. JP90 is used to connect
the overheat LED. The user can set the temperature range using
JP95. A buzzer can also be connected on JP89 that will sound off
that it is time to replace the power supply fan or the CPU cooling
fan. It is important that the back-up cooling fan be installed cor-
rectly in such a way that it will not only cool down the processor but
the whole system as well.
