Features 1
The AP61 is a high-performance system board that utilizes an Intel
PentiumÒ Pro (P6) processor running at 15 , 166, 18 , 2 MHz or
faster. It supports the PCI/ISA architecture and integrates the Intel
45 KX PCIset to improve system performance. This feature
conforms to the power-saving standards of the U.S. Environmental
Protection Agency (EPA) Energy Star program.
The system memory is expandable to 256 MB. It does not have an
onboard second-level cache since it is already included in the CPU
architecture.
The motherboard also incorporates a super I/O controller and a two-
channel PCI mode 4 IDE controller to further enhance system
performance. The board measures 22 mm x 33 mm (full baby-AT
size).

Features
System Board Parts
Microprocessor
The AP61 system board uses an Intel Pentium Pro (P6) processor
running at speeds of 15 , 166, 18 , 2 MHz or faster. Chapter 2
gives details on how to install and upgrade the Pentium processor.
ASICs
The ASICs (application-specific integrated circuits) onboard are the
Intel 82454, 82453, 82452, 82451 and Intel 82379. The Intel 82454
acts as the PCI/ISA-bus bridge that translates the PCI bus cycles. It
comes in a ball-grid array (BGA) packaging.
The Intel 82453 functions as the memory controller that supports both
the one-way and two-way interleave configurations.
The Intel 82452 serves as the memory controller data path that offers
64-bit DRAM and 32-bit PCI bus interfaces. Similar to 82454, this
chip also comes in a BGA packaging. It supports the Error Correcting
Code (ECC) feature that enables the system to correct the detected
data errors.
The Intel 82451 acts as the memory interface and the DRAM data bus
buffer.
The Intel 82379 operates as the PCI/ISA I/O controller that allows PCI
and ISA master/slave interfaces.
1-4 User’s Guide

Features
BIOS
The board supports the Award BIOS (basic input-output system)
which resides in the flash ROM chip. The BIOS contains the program
that performs the power-on self-tests (POST) upon booting. During
POST, this program activates the peripheral devices, tests onboard
memory, and prepares the system for operation. Chapter 3 gives
more information on the Award BIOS.
Expansion Slots
The board expansion slots consist of three ISA-AT and four PCI slots.
These expansion slots are the parallel bars on the system board.
There are rows of golden pins inside each slot that serve as a clutch
to secure the contacts of expansion boards.
The PCI slots accept three bus master (PCI slots 1, 2, 3) and one
slave PCI (PCI slot 4) devices. Chapter 2 tells how to install the
expansion boards.
DRAM Sockets
The system board has four 72-pin DRAM sockets that expand system
memory to a maximum of 256 MB. These sockets accept single- and
double-density single in-line memory modules (SIMMs). Chapter 2
discusses the different memory configurations available.
User’s Guide 1-5

Features
Two-channel PCI Mode 4 IDE Controller
The board utilizes the enhanced integrated drive electronics (IDE)
controller that improves data transfer rate. It also allows the system
to support four IDE devices, including hard disks with more than 528
MB capacity. This feature offers users increased data storage.
S per I/O Controller
The onboard super I/O controller chip supports two UART
1645 /1655 -compatible serial ports and a parallel port (SPP, EPP,
ECP)1. It also accommodates 1.2-MB, 1.44-MB, and 2.88-MB disk
drives allowing full-range access to 5.25-inch drives with 36 -KB or
1.2-MB format, and 3.5-inch drives with 72 -KB, 1.44-MB or 2.88-MB
format.
Keyboard Connector
The keyboard connector at the rear of the system board accepts any
AT-compatible keyboard. PS/2 keyboard and mouse connectors are
optional.
Second-level Cache
The system board does not have an onboard second-level cache
since it is already integrated in the Intel PentiumÒ Pro (P6) processor.
The processor comes with either 256-KB or 512-KB L2 cache size.

Chapter
Hardware Setup 2
This chapter tells how to install the CPU and other components, set
jumpers, configure system memory, install the system board, and add
expansion boards.
ESD Precautions
Electrostatic discharge (E D) can damage your processor, disk
drives, expansion boards, and other components. Always observe
the following precautions before you install a system component.
1. Do not remove a component from its protective packaging until
you are ready to install it.
2. Wear a wrist grounding strap and attach it to a metal part of the
system unit before handling components. If a wrist strap is not
available, maintain contact with the system unit throughout any
procedure requiring E D protection.
