Microprocessor
The AP61 system board uses an Intel Pentium Pro (P6) processor
running at speeds of 150, 166, 180, 200 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

The default setting is All Errors.
Memory
The Memory parameters are for display only. These are determined
by the BIOS POST.
Base Memory
The POST detects the amount of base (or conventional) memory
installed in the system. The value of the base memory is 640 KB for
systems with 640 KB or more memory installed on the mainboard.
Extended Memory
The BIOS detects the amount of extended memory present during the
POST. This is the amount of memory located above 1 MB in the CPU
memory address map.

Award BIOS
Expanded Memory
Expanded memory is the memory defined by the Lotus/Intel/Microsoft
(LIM) standard as EMS. Since a number of standard DOS
applications cannot utilize memory above 640 KB, the Expanded
Memory Specification (EMS) swaps the memory which is not utilized
by DOS with a section, or frame. This allows access to the total
system memory. The memory range that can be swapped by EMS
depends on the chipset design.
An expanded memory device is required to use memory as expanded
memory.
Other Memory
This refers to the memory located in the 640 KB to 1024 KB address
space. This is the memory that can be used for different applications.
DOS uses this area to load device drivers to keep as much base
memory free for application programs.

Slots 1, 2, 3 and 4 Using INT#
Each PCI slot supports four interrupt pins. These parameters let you
select which interrupt pin to use. The selections are interrupt pins A,
B, C, D and Auto. However, you must always start with interrupt pin
A. The INTA pin is automatically reserved for master function of the
PCI device. The remaining interrupt pins (INTB, INTC, and INTD) are
reserved for multifunction cards.
The default setting for these parameters is Auto. This automatically
sets the system IRQ for the PCI slot.
Available IRQs
These parameters let you assign a system IRQ to each PCI slot. The
available settings are 3, 4, 5, 7, 9, 10, 11, 12, 14, 15 and NA. The NA
setting means no IRQ is assigned to the slot. When assigning, make
sure that the IRQs do not conflict.
PCI IRQ Activated By
This option allows you to set when to activate the PCI IRQ. The
available settings are Edge and Level. The Edge is the start of the
signal and Level is the point at which the signal is high. The default
setting for this parameter is Edge.
PCI IDE 2nd Channel
This parameter lets you enable or disable the second channel of the
