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® P6DNH/P6DNH2 motherboard, which
supports the 200/180/166/150, >200 MHz Intel® Pentium® Pro processors, and the i960® RP IO processor.
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.

Chapter 1: Introduction
Chapter 1
Introduction
1-1 Overview
SUPER P6DNH/P6DNH2 is a high performance, I2OΤΜ enabled computer system board based on Intel® Pentium® Pro 200/180/166/150
MHz processors. They incorporate Intel's 440FX chipset and support dual processing. SUPER P6DNH uses the 33 MHz i960® RP I/
O processor while SUPER P6DNH2 uses the 66 MHz i960 RD I/O
processor.
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 transactions on the processor bus do not block subsequent bus transactions. For example, when a cache miss occurs, the processor will
continue to process other instructions while initiating a bus transaction 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 requests 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
1-1
SUPER P6DNH/P6DNH2 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 million transistors. The larger one is the CPU core with 5.5 million
transistors. The smaller one is the non-blocking cache which contains 15.5 million transistors.
The i960 RP/RD I/O processor is a highly integrated intelligent I/O
subsystem on a chip. Mode 3 is the default setting for its normal
operation. The i960 RP/RD has two main functions. As a local
processor, 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 enables 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. SUPER
P6DNH/P6DNH2 supports four primary and four secondary PCI
buses.
I2O is an open software-interface standard for I/O devices, independent of the specific device and operating system. It is implemented
on the i960 RP/RD I/O processor. With I2O, I/O hardware vendors
do not have to write drivers in countless variation, one for each
operating system version.
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 interfaces with the host operating system. The second interfaces with
the particular device, media or server managed by the driver. The
two modules interface with each other through a two-layered communications 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.
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
1-2
Chapter 1: Introduction
PCI standard is clearly defined to ensure complete compatibility. A
PCI add-on card available today will work in any PC-compliant system in the future. The PCI add-on card interface is processor independent. 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 feature auto-configurability for easy integration. The user-friendly BIOS
automatically allocates system resources for add-on cards and configures 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 eight 32-bit slots with industry standard PCI design 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), computeraided engineering (CAE), database management, desktop publishing, image processing, and artificial intelligence. The
motherboard’s additional three ISA slots provide standard 16-bit
compatibility for AT-type add-on card expansion.

motherboard. Figure 1-2 shows the architecture of the SUPER
