Static Electric Discharge Precautions
Static electric discharge can deliver a high-voltage shock
to the mainboard sufficient to damage or destroy components on the board. Because of this, it is important to
observe precautions when you handle the mainboard and
any devices you install on it, including the CPU, memory
modules and expansion cards.
There are several simple precautions you can take:
•
Use an anti-static wrist strap, which can be purchased inexpensively from most computer stores.
Connect the strap lead to a grounded metallic object and put on the strap before touching any components.
•
Put components on an anti-static pad or keep them
in their anti-static packaging until you install them.
•
If you don’ t have a wrist strap or pad, make sure
to touch a metallic object such as the system case
to ground yourself before handling any components.

See Section 4 for detailed CPU information.
Clock Generator Chip
Important Note
The PR5 uses one of several clock generator chips. The DS DIP switch block
settings vary depending on which chip is installed. To determine the correct
settings you need to know which clock chip is installed. The position of the
chip on the mainboard is noted above. The chip part information is printed
on the top of the chip. The options are:
ICS:
IC S 9 15 9 -1 4
PhaseLink:
PLL52C59-14T or PLL52C61-01 or PLL52C61-21
These clock generator chips support a “Normal” and a “Turbo” mode.
Normal mode is the CPU manufacturer’s rated clock speed. Turbo mode is
an overclock mode that increases the CPU’s clock speed by 2.5% over
the Normal rating. For maximum stability and compatibility you should
use the Normal mode for the CPU you are installing.

Important Note:
Double-sided Modules
There is an important limitation in using double-sided SIMM or DIMM modules. Double-sided modules in one bank
prevents the use of a corresponding
bank of the other type of module. For
example:
• If bank SIMM1/2 has 2-sided modules installed, you can not use the
DIMM2 socket.
• If bank SIMM3/4 has 2-sided modules installed, you can not use the
DIMM1 socket.
• If bank DIMM1 has a 2-sided module
installed, you can not use the SIMM3/
4 sockets.
• If bank DIMM2 has a 2-sided module
installed, you can not use the SIMM1/
2 sockets.
Double-sided modules are modules with
memory chips mounted on both sides.
The PR5 has numerous possible system memory configurations using the four 72-pin SIMM sockets and the two
168-pin DIMM sockets. The SIMM sockets work in banks
of two to provide a 64-bit data path. SIMM1/SIMM2 are
one bank, SIMM3/SIMM4 are another. The DIMM sockets are each a bank, for a total of four banks. Please note
the following.
•
Installed memory is auto-detected by the BIOS
•
Minimum installation 2 SIMMs or 1 DIMM module for a 64-bit data path
•
Fast Page (FP), EDO and SDRAM are all supported,
SDRAM only in DIMM modules
•
SIMMs: single or double-sided modules of 4MB and
up supported
•
DIMMs: single or double-sided modules of 8MB
and up supported
•
DIMM sockets support both 5-volt (FP or EDO)
and 3.3-volt (Unbuffered) DRAM; voltage for both
sockets is set by jumper JP11 (see next page)
•
Pairs of SIMMs must be the same memory type,
size and speed but the type and size of a second
pair can be different
•
Memory Banks:
SIMM1 & SIMM2
SIMM3 & SIMM4
DIMM1
DIMM2
•
Bank sequence doesn’ t matter, use any combination as long as other requirements are followed
•
DRAM speed must be at least 70ns, can be faster
•
Parity checking is not supported
•
Maximum 128MB supported
There are numerous allowable memory configurations.
Since bank sequence is not important, as long as you use
SIMMs in pairs you can use any combination of banks.
However, for maximum performance it best to use the
same type of DRAM in all banks installed. SDRAM provides higher performance than EDO DRAM and EDO is
faster than Fast Page Mode DRAM.
DIMM Voltage Settings
!
The DIMM sockets support both 5-volt and 3.3-volt unbuffered DRAM. The voltage setting for both DIMM
sockets is controlled by jumper JP11. The socket voltage
setting must match the voltage of the DRAM on any
DIMM modules you install. The jumper settings are
shown below.
DIMM Voltage Settings
Jumper JP11 sets the voltage supplied to the DIMM sockets. FP & EDO
modules use the 5-Volt setting.
Default Setting : 3-Volt.

PR5 Hardware Configuration
This section describes how to configure the PR5 mainboard hardware in more detail than the Configuration
Quick Reference at the beginning of this section. It is intended for users who are less familiar with computer
hardware. If your PR5 is already installed in a system you
will not need much of this information unless you need
to reconfigure your system.
This section covers all the standard features on the board
plus the upgrade options. Since you are more likely to
need the upgrade options, they come first. The section is
organized as follows
•
CPU Options & Installation
•
System Memory Configuration
•
Level 2 Cache Options
•
Onboard Connectors
•
DIP Switch and Jumper Summary
The information in this section augments the Configuration Quick Reference. So these sections provide additional
detail, with some review.
CPU Options & Installation
The PR5 supports a wide assortment of CPU chips from
various manufacturers. It is also designed to provide as
much upgradability as current information on future CPUs
allows. We must note, however, that only the CPUs listed
in the manual have been certified to work with the PR5.
Related Terminology
To make it easier to understand the information this section you may want to review the following terms.
Clock
You’ ll see this term used in several ways. Here it
doesn’ t refer to keeping time and is not the clock
that keeps the date and time setting for the system. The mainboard relies on the system clock to
provide digital timing pulses at a constant frequency. The signal the clock generates synchronizes all operations on the board. This “ clock frequency” , or the number of signals per second is
what we usually think of as the clock “ speed” of
the system.
In Pentium-based designs there is more than one
clock speed. The mainboard components run at one
speed and the CPU will run at the same speed in
its external activity, but will run at some multiple
of that speed internally.
External Clock
The External Clock, also sometimes referred to as
the external CPU clock or bus clock, is the CPU’ s
input clock. The CPU will interface with other components at this speed and its internal clock speed is
a multiple of this external speed. The internal speed
is set by the Clock Multiplier Factor. For example,
the Intel Pentium P90, P120 and P150 CPUs all have
the same external clock, 60MHz, but have different clock factors.
Internal Clock
The Internal Clock is a multiple of the external clock
and is the speed used to list the processor’ s operating speed. The internal speed is set by the Clock
Multiplier Factor. For example, the Intel Pentium
P150 CPU has a 150MHz internal clock speed, a
2.5 multiple of the 60MHz external clock.
Clock Multiplier Factor
The clock multiplier factor is the factor by which
the external clock is multiplied to set the CPU’ s
internal clock speed. The PR5 has four options: 1.5,
2, 2.5, 3. For example, the Pentium P166 requires a
66MHz external clock and a 2.5 clock multiplier
factor to establish its 166MHz internal clock speed.
Note: The full clock frequencies are rounded off
for convenience when listed, so while 66 x 2.5 =
165, the actual clock speed is 166MHz.
ISA Bus Clock
This is the clock speed of the ISA expansion bus
and may also be referred to as the ISA speed, AT
Bus Clock or AT clock. The original specification
was 8MHz. The slower speed ensures compatibility with all ISA expansion cards. Newer ISA expansion cards may be able to operate at faster
speeds, which provide increased performance. The
PR5 can be set for slower or faster ISA Bus clock
speeds. The slower speed ensures maximum compatibility.
CPU Voltage – Vcore & Vio
The CPU input voltage has two components, Vcore
and Vio. Vcore provides the power for internal processing and Vio for the external interface. The two
settings are linked, so the VC DIP settings cover
both of them.
P–Rating
The “ P–Rating” is a categorization used to rate the
performance of some Pentium-compatible CPUs.
The rating system was created because some CPUs
perform at a higher effective speed than their internal clock speed indicates. For example, the Cyrix
6x86 P166+ has a clock speed of 133MHz, but performs at an effective speed equal to or greater than
166MHz. The P–rating indicates the effective,
rather than the actual clock speed of the CPU.
CPU Settings
☞
To configure the PR5 for the CPU you will install you
have to set the switches on the two CPU configuration
DIP switch blocks DS and VC. The procedure is as follows:
1. Set the Clock Multiplier Factor using switches DS1
and DS2 on the DS DIP switch block.
2. Set the External Clock configuration using switches
DS3, DS4 and DS7 on the DS DIP switch block.
3. Set the ISA Bus Clock configuration using switch
DS5 on the DS DIP switch block.
4. Make sure DS6 on the DS DIP switch block is OFF.
This controls DRAM refresh and is reserved for use
with future CPUs. The default setting is OFF.
5. Make sure DS8 on the DS DIP switch block is OFF.
This is reserved for use with future CPUs. The default setting is OFF.
6. Set the Vcore/Vio configuration using the VC DIP
switch block.
7. Make sure jumper JP10 is set to the default “ Open”
setting (no jumper cap connecting the two pins).
In order to give you more CPU configuration options
we have included Turbo settings which increase system
performance somewhat as well as the standard CPU configurations which maintain maximum stability and compatibility. The Turbo settings are labeled as such and all
other settings are standard. The charts on the following
pages show the settings for various CPUs.

System Memory Configuration
The PR5 is designed to provide the broadest possible
memory configuration options. The design includes four
sockets for the currently most common form factor, 72pin SIMM modules and also has two sockets for the future standard, 168-pin DIMM modules. The DRAM on
the SIMM modules can be either Fast Page mode or EDO
DRAM. DIMM modules can use these and can also use
the newer SDRAM (Synchronous DRAM). You can install a combined total 128MB of all memory types on the
PR5 mainboard.
Pentium-type CPUs are 64-bit CPUs. This has a direct
effect on the memory design. Since 72-pin SIMM sockets are 32-bit, they have to be used in pairs to create a 64bit data path. This means that SIMM modules have to be
installed in pairs. The four SIMM sockets on the PR5 are
therefore divided into “ banks” of two sockets each, resulting in two banks. Because DIMM sockets are 64-bit,
each DIMM functions as a bank, resulting in another two
banks for a total of four banks on the mainboard. The
SIMM banks are organized so that SIMM1/SIMM2 are
one bank, SIMM3/SIMM4 are another. The figure below
shows the socket numbering.

DIMMs
The PR5 has numerous possible system memory configurations using the four 72-pin SIMM sockets and the two
168-pin DIMM sockets. Please note these guidelines:
•
Installed memory is auto-detected by the BIOS
•
Minimum installation 2 SIMMs or 1 DIMM module for a 64-bit data path
•
Fast Page (FP), EDO and SDRAM are all supported,
SDRAM only supported on DIMM modules
•
SIMMs: single or double-sided modules of 4MB and
up supported
Important Note:
Double-sided Modules
•
DIMMs: single or double-sided modules of 8MB
and up supported
There is an important limitation in using double-sided SIMM or DIMM modules. Double-sided modules in one bank
prevents the use of a corresponding
bank of the other type of module. For
example:
• If bank SIMM1/2 has 2-sided modules installed, you can not use the
DIMM2 socket.
• If bank SIMM3/4 has 2-sided modules installed, you can not use the
DIMM1 socket.
• If bank DIMM1 has a 2-sided module
installed, you can not use the SIMM3/
4 sockets.
• If bank DIMM2 has a 2-sided module
installed, you can not use the SIMM1/
2 sockets.
Double-sided modules are modules with
memory chips mounted on both sides.
•
DIMM sockets support both 5-volt (FP or EDO)
and 3.3-volt (Unbuffered) DRAM; voltage for both
sockets is set by jumper JP11 (see below)
•
Pairs of SIMMs must be the same memory type,
size and speed but the type and size of a second
pair, and any DIMMs can be different
•
Memory Banks:
!
SIMM1 & SIMM2
SIMM3 & SIMM4
DIMM1
DIMM2
•
Bank sequence doesn’ t matter, use any combination as long as other requirements are followed
•
DRAM speed must be at least 70ns, can be faster
•
Parity checking is not supported
•
Maximum 128MB supported
There are numerous allowable memory configurations.
Since bank sequence is not important, as long as you use
SIMMs in pairs you can use any combination of banks.
However, for maximum performance it best to use the
same type of DRAM in all banks. SDRAM provides higher
performance than EDO DRAM and EDO is faster than
Fast Page mode DRAM.
The chart on the next page gives examples of some of
the possible configurations.

DIMM Voltage Settings
The DIMM sockets support both 5-volt and 3.3-volt unbuffered DRAM. The voltage setting for both DIMM
sockets is controlled by jumper JP11. The socket voltage
setting must match the voltage of the DRAM on any
DIMM modules you install. The jumper settings are
shown below.

Installing Memory Modules
Installing memory modules is easy, but there are a few
important precautions you should take whether you are
installing SIMM or DIMM modules.
The most important is to guard against damage to the
modules from static discharge. A strong enough discharge
can make a module unusable and ruin your investment.
If you’ re not familiar with static precautions, you may
want to review the information on this in Section 1.
In addition to taking precautions against damage from
static discharge, you should avoid touching a module’ s
edge connector when you are handling it. The edge connector is the part of the module that inserts in the socket
on the mainboard. Oil from your fingers can cause corrosion on the connector contacts as well as in the sockets,
possibly resulting in an eventual malfunction.
Module Orientation
All memory modules must be oriented correctly before
you can insert them in the socket. SIMM and DIMM
modules have different designs for ensuring correct module orientation.
SIMM modules have one lower corner cut away to ensure they will only insert in a socket in the correct orientation. The SIMM sockets have an extension from one of
the socket guide posts that prevents the module from inserting in the socket if it isn’ t oriented correctly.
DIMM modules have a long edge connector divided into
sections, two longer and one shorter. The DIMM sockets
are divided accordingly, so the orientation is obvious.
Installing SIMMs
To install any kind of SIMM module do as follows:
1. Orient the cut-away corner so that it is at the lower
end of the socket.
2. Insert the module edge into the socket at about a
45° angle so that the contacts are as far in as they
will go.
3. Push the module up into the retaining clips so that
the clips clamp over the edge of the module. The
holes at each end of the module should fit over the
protrusion on the guide post.
It is a good idea to use the sockets from left to right to
make installation easier.
Installing DIMMs
To install any kind of DIMM module do as follows:
1. Orient the short section of the edge connector so
that it is at the upper end of the socket.
2. Insert the module edge into the socket at a 90° angle
so that the contacts insert as far as they will go.
3. The retaining clamps at each end rotate upward to
secure the module in the socket.
The figure below shows where the orientation features
are located.

Level 2 Cache Options
The Level 2 cache on the PR5 greatly speeds up system
operation. There will be at least 256KB of very fast Pipeline Burst Static RAM (SRAM) cache memory mounted
either on the mainboard or on a cache module that installs in the cache socket. You can upgrade the Level 2
cache to a maximum of 512KB regardless of whether the
memory is on the board or on a module.
If there is 256KB of cache memory mounted on the
mainboard, you can use a 256KB cache module to upgrade the Level 2 cache to 512KB. See the cache options
in the following table. Jumper JP1 sets the cache size.

There are several connectors for various features on the
mainboard. If your PR5 is already installed in a system,
you can skip this section. The PR5 has onboard connectors for the floppy and hard disk controllers, I/O ports,
connections from your system case and several other features. Their locations are shown in the Configuration
Quick Reference, so they are not repeated here. This section explains what the connectors are and how they work.
Disk Drive Controller & I/O Port Connectors
The PR5 has floppy disk drive and Enhanced IDE controllers built-in. The EIDE controller is for both hard disk
drives and other devices which have an EIDE interface
such as CD-ROM drives. You connect disk drives or other
devices to the connectors on the mainboard using cables
that come with it.
The PR5 also has I/O (Input/Output) ports built-in including serial, parallel and USB port connectors onboard.
External ports connect to the onboard connectors via the
cables attached to ports.
Drive Controller Connectors
The PR5 comes with ribbon cables to connect your system floppy disk and IDE drives to the mainboard. The
cables are colored on one edge to show you how to orient the cable. That edge of the cable must be at the Pin 1
end of the onboard connector when connected.
The Floppy Disk Drive Controller connects to your system floppy drive or drives with the floppy drive ribbon
cable that comes with the PR5. One end of the cable attaches to the FDC connector on the mainboard and the
other attaches to the floppy disk drive. There are three
connectors on the cable, one at each end and one in between, closer to one end than the other. Floppy drive A:
attaches to the end of the cable and drive B:, if you have
one, attaches to the connector in the middle. The connector at the other end connects to the mainboard.
The two Enhanced IDE Controller connectors are for the
two IDE channels Channel 1 and Channel 2. Channel 1
is the Primary channel and is divided in two as the Primary Master and Primary Slave. Channel 2 is the Secondary channel and is organized the same way. There
are ribbon cables for each channel. Enhanced IDE allows
a total of four devices, two attached to each IDE channel.
The first device in each channel attaches to the end of
the cable. A second device attaches to the connector in
the middle and the other end of the cable attaches to the
mainboard.
Your start-up (boot) IDE hard disk drive must be connected as the Primary Master (end of the cable). You can
attach a second hard drive in any of the other three available positions.
The location of the connectors and their Pin 1 positions
are shown in the Configuration Quick Reference.
I/O Port Connectors
The PR5 has two serial ports, a parallel port, an infrared
port and a dual-port USB connector onboard. Combination ribbon cable-to-external port cables are supplied for
each connector except the infrared port. The I/O ports
enable you to connect external devices such as modems
and printers to your system. The serial ports are the
COM1 and COM2 ports and the parallel port is the LPT1
printer port. There are also some other devices which
have a parallel interface and can connect to the LPT port.
An example of this kind of device is a parallel interface
external tape backup drive.
The IR (InfraRed) and USB ports are both a new type of
PC port. The IR port allows wireless two-way communication between your computer and other devices with
IR capability. The Universal Serial Bus is a new specification for connecting external peripheral devices with the
same interface.
The location of the connectors and their Pin 1 positions
and the pin assignments for the Infrared and USB ports
are shown in the Configuration Quick Reference.
System Enclosure Connectors
The system enclosure is your system case. There are usually several features built-in to the case that connect to
the mainboard. The PR5 has connections for a number
of these in a connector block which includes connectors
for a Reset button, Suspend switch, Turbo LED, Speaker
and Keyboard lock. Your system case may or may not
have all of these features.
The location of the connector block and the pin assignments are shown in the Configuration Quick Reference.
Other Connectors
There are several other connectors on the PR5, including
the power input, keyboard, PS/2 mouse, IDE activity LED
and CPU fan connectors. Their locations and pin assignments are shown in the Configuration Quick Reference.
Power Input Connector
The system power supply connector is a 12-pin connector, divided into two sections, P8 and P9. The leads from
the system power supply plug onto this connector and
snap into place. If you connect the leads yourself make
sure you plug them on so that the black wires on each
lead are in the middle of the connector.
Keyboard & PS/2 Mouse Connectors
The external keyboard connector is a standard “ AT” DIN
keyboard connector. The PS/2 connector is a 6-pin block
for the PS/2 mouse port cable.
The PR5 accepts two keyboard types, the AT keyboard
with its larger jack fits the onboard keyboard connector
directly. A PS/2 keyboard, which has a smaller jack, connects to the keyboard port with a PS/2-to-AT jack adapter.
The onboard PS/2 connector is for the PS/2 mouse port.
If you want to use this type of mouse in your system,
you can connect it to the external PS/2 port.
The keyboard connector and PS/2 port pin assignments
are shown in the following table.

IDE Activity LED Connector
The IDE activity LED connector is a 4-pin connector
which will accept either a 2-pin or 4-pin IDE LED activity light connector. This light comes on when an IDE
device in your system is being accessed. If you are connecting a lead from an LED activity light on your case,
make sure you identify which wire is the positive wire
and orient the lead’ s connector so that the positive wire
connects to the positive pin on the onboard connector.
The pin connector assignments are in the Configuration
Quick Reference if you need them.
CPU Fan Power Connector
The CPU fan power connector is a 3-pin connector header
which will accept either a 2-pin or 3-pin CPU fan power
lead connector. Some CPU fans have a connector for a
standard power lead from the system power supply. If
your CPU fan is attached to the top of the CPU chip, as
with some Intel Pentiums, the power lead connector
should fit this onboard connector. If you are connecting a
lead from a CPU cooling fan to this connector, make sure
you identify which wire is the positive wire and orient
the lead’ s connector so that the positive wire connects to
the positive pin on the onboard connector. The pin connector assignments are in the Configuration Quick Reference if you need them.

There are two other jumpers on the PR5 which have not
been mentioned yet. One is JP3 (Clear CMOS Memory)
and the other is JP8 (Flash ROM Type).
JP3: Clear CMOS Memory
The onboard CMOS memory is where the system configuration information set by the BIOS Setup program is
stored. If you make entries in the Setup program that will
prevent the computer from booting up or you set a password and then forget it, you will not be able to use the
computer. If this happens, you must clear (erase) the
CMOS memory and enter new configuration information in the BIOS Setup program. The BIOS Setup program is covered in Section 3.
To clear the CMOS memory do as follows:
1. Remove the jumper cap from Pins 1&2
2. Place the cap over Pins 2&3 for five seconds
3. Replace the cap over Pins 1&2
When you are done, you can start up your computer and
run the Setup program to re-enter the system configuration information. The location of JP3 is shown below.

T he B I OS CM OS Se tu p U til ity
The PR5 uses the Award system BIOS. The BIOS (Basic
Input Output System) is the basic software the computer
needs to enable the system hardware components to
operate together. It is stored in a Flash ROM memory
chip on the mainboard. The BIOS uses a software program, also stored on the same chip to create a system
configuration record which is saved in a small amount of
special “ CMOS” memory which is also on the board.
This Setup program records information about the system hardware including the disk drives installed, system
m em ory and vide o dis play. It also rec ords sys tem
customization information and settings for the mainboard’ s chipset, power management and configurable
hardware. In addition, the Setup program has a Password
feature, automatic hard disk detection and a hard disk
low level format command.
Accessing The CMOS Setup Utility
When you turn on your computer, a message appears on
the screen saying you can call up the Setup program. The
message appears after the POST (Power On Self Test):
TO ENTER SETUP BEFORE BOOT PRESS CTRL–ALT–ESC OR DEL KEY
If you want to run Setup but you don’ t respond in time
before the message disappears, you can reset the system
by pressing the Ctrl + Alt + Delete keys at the same time,
or by pushing the system Reset button. The message will
then reappear.
After you press the Del key the program menu screen
will appear, displaying the various sections of the Setup
utility and some commands.

The first two lines on the screen are the date and time
settings for the system clock.
Hard Disk Type & Parameters
Use the IDE HDD Auto Detection feature to automatically enter the drive parameters of IDE hard disk drives
in these fields. If you have only SCSI hard disk drives
installed in your system leave the settings here at None.
Only hard disk information needs to be entered here.
Other IDE devices do not use this.
For an IDE hard drive, you should set the entry to “ Auto”
and the BIOS will automatically detect all drive information needed. You can use the IDE HDD Auto Detection
utility described later to supervise the auto-detection process. If you want to do this, leave the drive set to “ None” .
You can also enter specifications manually by using the
“ User” option.
Large Hard Disk Modes
The last of the drive parameter entries – Mode – has three
options, Normal, LBA and Large. The Mode settings are
for IDE hard disks only, and it is important to understand
their function.
N or m a l
For IDE hard disks of 528MB or less.
LBA
This stands for Logical Block Addressing, the current standard access mode for large IDE hard disk
drives. It allows the use of hard disks larger than
528MB by causing the IDE controller to translate
between the logical address it creates and the hard
disk’ s actual physical address. The maximum drive
size supported is 8.4GB.
Large
For 1GB or smaller drives with more than 1024 cylinders and no LBA support. This access mode
causes the Operating System to treat the drive as if
it has fewer than 1024 cylinders by dividing the
cylinder total in half and doubling the number of
heads. Drives needing this mode are less common.
Most large IDE hard disk drives currently available use
the LBA mode.
Floppy Disk Drives
The two floppy disk drive items set the drive type for
drives A and B, and must be entered manually. The options are
360KB, 5.25 in.
1.2MB, 5.25 in.
720KB, 3.5 in.
1.44MB, 3.5 in.
2.88MB, 3.5 in.
None
Highlight the listing after each drive name and select the
appropriate entry.
Floppy 3Mode Support
3Mode is a Japanese 3.5-inch floppy disk drive specification. If this type of drive is installed you should enable
this feature. The default setting is Disabled.
Video Display Types
You set this according to the type of display card in your
system. This should normally be left on EGA/VGA. The
options are:
EGA/VGA
Mono (for Hercules or MDA)
CGA 40
CGA 80
Error Handling
The last line – Halt On – sets when the system stops if an
error occurs. The options are:
All Errors (Default)
No Errors

Virus Warning
This protects the primary hard disk’ s boot sector and partition table from infection. Any attempt to write to them
will halt the system and produce a warning message. If
this happens, you can either allow the system to continue or stop it and boot from a virus-free bootable floppy
disk. Use an anti-virus utility located on the floppy disk
to check the hard disk. The default setting is Disabled.
CPU Internal Cache
This enables CPU’ s Level 1 built-in cache. Leave it enabled to maintain system performance. The default setting is Enabled.
External Cache
This is the Level 2 external cache of either 256KB or
512KB. Leave this enabled to maintain system performance. The default setting is Enabled.
Quick Power On Self Test
This feature speeds up the Power On Self Test (POST) by
skipping some parts of the POST. If your system is functioning normally, you can enable this feature to speed
the boot process. The default setting is Enabled.
Boot Sequence
This determines the order in which the computer checks
drives for an operating system. This allows you to configure the system to boot from a CD-ROM drive as well
as the drive A: floppy disk drive and the drive C: boot
hard disk. The options are:
A, C
C,A
C, CD-ROM, A
CD-ROM, C, A
Swap Floppy Drive
This switches the floppy drive assignments so that drive
A is treated as drive B: and drive B: as drive A: under
DOS. The default setting is Disabled.
Boot Up Floppy Seek
When enabled, the BIOS checks the floppy disk drive(s)
to see if they are 40-track (360KB floppy disk drive) or
80-track (all other types). Don’ t enable this unless your
system has a 360KB floppy drive. The default setting is
Disabled.

Video BIOS Shadow
The Shadow Feature
The term “Shadow” mentioned at right
refers to a performance enhancement
feature whereby the system BIOS and
video display card BIOS are copied into
system DRAM to speed up system operation. The system BIOS is always
shadowed. It is highly advisable to
shadow the video BIOS. The other address range options allow shadowing of
any other expansion card installed in
your system that has a BIOS.
This copies the video display card BIOS into system
DRAM to increase display speed and is required for system performance. The default setting is Enabled.
Shadowing Address Ranges
The next six lines, from C8000-CBFFF Shadow to DC000DFFFF Shadow are address ranges for shadowing other
expansion card ROMs. If there are any expansion cards
with ROMs installed in your system, you have to know
the address range they use to shadow them specifically.
The default setting for all of these is Disabled.

Award BIOS Power Management Setup
Menu Commands
The menu commands for this screen are the same as for
the BIOS Features Setup screen.
What Power Management Does
Power management lets you set up your computer to save
electricity when it is not actively in use by putting the
system into progressively greater power saving modes.
In the power management scheme there are four system
states which proceed in the following sequence:
Normal ♦
¬
Doze
¬
Standby
¬
Suspend
Power Management
This controls the entire power management scheme.
There are four settings:
User Defined
You set the power saving options manually
Disable
Turns off all power management
Max Saving
Maximizes power saving by activating maximum
power saving settings after one minute of system
inactivity
Min Saving
Produces less power saving by activating moderate power saving settings after one hour of system inactivity
PM Control By APM
W hen this is set to Yes the Advanced Power Management feature in Microsoft Windows controls power management operation. The default setting is No.
Video Off Method
This governs monitor power saving by controlling how
power management blanks the monitor screen. The default setting blanks the screen and turns off vertical and
horizontal scanning and requires a monitor with “ green”
features. If you don’ t have this type of monitor, use the
Blank option. DPMS (Display Power Management System) allows the BIOS to control the video display card if
the card has the DPMS feature.
V/H SYNC+Blank
(Default)
Blank
(Non-green monitor, less saving)
DPMS
(Display card must support DPMS)
Video Off Option
This governs in what modes the video display gets turned
off. The options are:
Susp,Stby-> Off
(Off in Suspend & Standby)
Susp-> Off
(Off in Suspend)
All Modes Off
Always On
(Off in Doze, Suspend & Standby)
(No video shut off)
Modem Use IRQ
If you have a modem installed in your system you can
enter which IRQ it is using so that APM can control it.
The default setting is NA (Not Applicable).
Doze Mode
This sets the period of system inactivity after which the
system goes into Doze mode, the most limited power
saving state. The settings range from 1 minute to 1 hour
and can be set manually when power management is in
User Define mode. The default setting is Disabled. When
the system goes into power saving mode, power management will skip to the next mode in the sequence if
this is disabled.
Standby Mode
This sets the period of system inactivity after which the
system goes into Standby mode, the intermediate power
saving state. The settings range from 1 minute to 1 hour
and can be set manually when power management is in
User Define mode. The default setting is Disabled. When
the system goes into power saving mode, power management will skip to the next mode in the sequence if
this is disabled.
Suspend Mode
This sets the period of system inactivity after which the
system goes into Suspend mode, the maximum power
saving state. The settings range from 1 minute to 1 hour
and can be set manually when power management is in
User Define mode. The default setting is Disabled. When
the system goes into power saving mode, power management will skip to the next mode in the sequence if
this is disabled.
HDD Power Down
This shuts down IDE hard disks that support a power
saving mode after a specified time period. The settings
range from 1 to 15 minutes and can be set manually when
power management is in User Define mode. HDD Power
Down does not affect SCSI hard disks. The default setting is Disabled.
The system automatically resumes from any power saving mode when there is system activity such as keyboard
activity or an IRQ wake-up event like mouse movement
or a modem ring.
Wake Up Events In Doze & Standby
The system will resume from Doze or Standby mode if
there is any activity by the parts of the system that use
the IRQs listed in this section when they are set to ON.
The system won’ t wake up from such activity if an item
is set to OFF. The default settings are set so that the system will respond to mouse or modem activity. The default settings are:
IRQ3 (Wake-Up Event)
IRQ4 (Wake-Up Event)
ON
ON
IRQ8 (Wake-Up Event)
OFF
IRQ12 (Wake-Up Event)
ON
Power Down & Resume Event
This section allows setting the resume status of individual
IRQs. When set to ON, activity will wake up the system.
When set to OFF activity is ignored.
When you are finished you can press the Esc key to return to the main menu.

Menu Commands
The menu commands for this screen are the same as for
the BIOS Features Setup screen.
PCI PnP BIOS Auto-Config
This function will automatically assign IRQs to PCI expansion slot INT#s as needed when enabled. If disabled,
IRQs are assigned via the Available IRQ settings that follow after the next item. The default setting is Disabled.
PCI IRQ Actived By
The Level setting is required, don’ t change it.
Available IRQ
These four lines allow setting which IRQs will be assigned
as needed to PCI expansion slot INT#s. The sequence
controls the order in which the IRQs are assigned. The
system looks at the PCI slots in the order Slot 1, 2, 3. The
IRQ options are 3, 4, 5, 7, 9, 10, 11, 12, 14 and 15.
PCI IDE Card 2nd Channel
This turns the onboard IDE controller’ s second channel
on and off. If you disable this it makes IRQ15 available
to the ISA expansion bus. The default setting is Enabled.
PCI IDE Card IRQ Map To
This item sets how the system assigns IRQs to a PCI IDE
controller card installed in one of the PCI expansion slots.
There are four options for this item. The default setting
is PCI-AUTO. The options are:
PCI-AUTO
Automatically assigns IRQ14 to the INT# for the
slot the card is installed in.
PCI-slotX
If an installed PCI IDE card does not support autodetection, you have to enter which slot it is installed
in by selecting the slot number. IRQ14 will be assigned automatically.
ISA
This for PCI IDE cards that connect to IRQs 14 and
15 directly via a “ paddleboard” installed in an ISA
slot and connected to the card by a cable. No IRQ
is assigned to the slot with the PCI IDE card in it.
The PCI Slot INT# specification options are:
Slot1–INT#A; Slot2–INT#B; Slot3–INT#C; Slot4–INT#D
Slot1–INT#B; Slot2–INT#C; Slot3–INT#D; Slot4–INT#A
Slot1–INT#C; Slot2–INT#D; Slot3–INT#A; Slot4–INT#B
Slot1–INT#D; Slot2–INT#A; Slot3–INT#B; Slot4–INT#C
In each case above the Slot/INT# associations are assigned
the same IRQ. This means you can not install more than
one PCI expansion card that uses an IRQ.
PS/2 Mouse Function (IRQ12)
This turns the PS/2 mouse port on and off. The default
setting is Enabled.
☞
Onboard IDE-1 Controller
PIO Modes 0 ~ 4
The transfer mode settings for the IDE
controller are best set automatically. If
you want to set them manually, you
must check which mode the hard disk
in question supports. New IDE hard
drives will provide this information, usually noting the fastest mode supported.
Mode 0 is the slowest and Mode 4 the
fastest. If a drive supports a faster
mode, it also supports all modes slower
than the one listed.
This turns the onboard IDE controller’ s Primary channel
on and off. The default is Enabled. The two sub-items
set the PIO transfer modes for the Master and Slave devices. The Auto setting automatically determines the best
mode for the device. Alternatively, you can set the mode
manually to Mode 0, 1, 2, 3 or 4.
Onboard IDE-2 Controller
This turns the onboard IDE controller’ s Secondary channel on and off. The default is Enabled. The two sub-items
set the PIO transfer modes for the Master and Slave devices. The Auto setting automatically determines the best
mode for the device. Alternatively, you can set the mode
manually to Mode 0, 1, 2, 3 or 4.
Onboard FDD Controller
This turns the onboard floppy disk drive controller on
and off. The default setting is Enabled.
Onboard Serial Ports 1 & 2
These two lines set the address and IRQ assignment or
disable the onboard serial ports. The default settings are
the standard assignments for these ports. You can choose
another option or disable them if you want. Don’ t use
the same settings for both ports. The settings are as follows:
Serial Port 1
3F8/IRQ4
(Default)
Serial Port 2
2F8/IRQ3
(Default)
Other Options:
3E8/IRQ4
2E8/IRQ3
Disable
All options are for either port.
IR Infrared Settings
The next three items configure Serial Port 2 as an Infrared port as follows:
Onboard IR Function
This sets the IR mode. The options are:
HPSIR – HP IrDA compatibility
ASKIR – Amplitude Shift Key IR
Disable – No IR
IR Duplex Mode
Sets the Duplex Mode to either Half or Full. The
default is Half.
IR Tr/Re Polarity
Sets the IR transmit and receive polarity to either
High or Low. The default setting is Hi/Hi.
Onboard Parallel Port
This sets the address and IRQ assignment or disables the
onboard parallel port. The default setting is the standard
assignment for parallel ports. You can choose another option if you want. The default setting is 378/IRQ7.
Parallel Port Mode
The onboard parallel port supports standard, EPP and ECP
modes. The default setting is Normal(SPP). The options
are as follows.
EPP 1.7
EPP 1.9

You should not need to use this program when you install an IDE drive and you should make sure that you can
use this generic formatter on your drive in the unlikely
event that it needs to be low level formatted again.
Low level formatting is not the same as the formatting
you perform when installing an operating system.
In the event that you need to use this utility, the drive
you use it on must be set to Normal mode in Standard
CMOS Setup.

The PR5’ s BIOS chip is programmable and can be updated when new BIOS versions are released.
IDE Driver Disk
The PR5 comes with a floppy disk of IDE Bus master
drivers for the PIIX IDE controller. There are drivers for
Windows95, Windows NT and OS/2. There are Readme
text files for each version which explain how to use the
drivers. They are on the floppy disk in the relevant directories for each operating system.

CP U S pec if icatio ns
This section is made up of tables and diagrams designed
to help you identify the CPU you want to install. You
need to identify your CPU in order to determine the correct configuration settings.
CPU’ s from Intel, AMD, and Cyrix are covered here. CPUs
vary within a specific type; a 120MHz Pentium for example, can have different power and timing specifications depending on which type and “ Step” (version) it is.
To identify a CPU you’ ll need to examine the chip to
obtain specification information that is printed on the
chip. The diagrams for AMD and Cyrix CPUs explain
how to interpret the information on the chip.
Intel CPUs
This section lists the specifications for Intel Pentium
CPUs. The following tables use some abbreviations as
follows:
Power
STD – 3.15V ~ 3.465V (Suggested setting 3.38V)
VR – 3.3V ~ 3.465V (Suggested setting 3.38V)
VRE – 3.45V ~ 3.6V (Suggested setting 3.52V)
Ti m i n g
STD – Standard Timing
MD – Minim um Delay (Shorter m inim um valid
delay AC timing for some signals)
KIT – Supports timing for C55/C88 cache chipsets
Also, please note the following:
P54C
Beginning with the P54C E-Step, Standard timing
was replaced by existing Min Delay timing.
P54CS
P54CS PPGA UP:No DP, No APIC, No FRC
Beginning with the P54C E-Step, Standard timing
was replaced by existing Min Delay timing.
P55C
P55C A-Step is NOT a production stepping.
A-1 Step: Vcc and timing on initial samples is 2.9V
+/- 0.1V.
A-2 Step & B Step: Vcc and timing on production
stepping is 2.8V +/- 0.1V.

IDE Installation Guide
This section is a guide to installing IDE devices in your
computer system. It covers installing devices you connect to the mainboard’ s onboard Enhanced IDE controller. The main hard disk drive used in most systems is an
IDE device. In addition to this, however, you may want
to install more hard disks, a CD-ROM drive or combination of these. The onboard controller supports up to four
devices. The purpose of this section is to provide some
background information regarding the process and give
some example configurations.
IDE Transfer Modes
Hard disk read/write operations are performed via the
mainboard’ s chipset. The transfer of data between the
hard disk and the system takes place via one of several
transfer modes – PIO mode, Master mode or DMA mode.
Master Mode
In Master mode, when the system reads data, the
mainboard chipset performs hard disk read operations directly using either PIO or DMA and places
retrieved data in the system memory.
PIO Mode– Programmed Input/Output
In PIO mode, to read data, the CPU issues I/O commands to the mainboard chipset to perform hard
disk read operations and place retrieved data directly in the system memory. There are several PIO
modes, categorized as Mode 0 ~ 4.
DMA Mode – Direct Memory Access
The direct transfer of data between the system
memory and the hard disk where the mainboard
chipset performs hard disk read operations directly
and places retrieved data in the system memory
independent of the CPU.
All of these modes provide faster data transfer.
Installing IDE Devices
The Enhanced IDE controller on the PR5 supports four
devices in two channels, IDE1 and IDE2, which are also
referred to as the Primary and Secondary channels.
Each channel supports two devices, the first device is
called the Master and the second device the Slave. IDE
devices must be configured to operate as one or the other.
To find out how to configure the drive hardware you
should check the documentation that comes with the
drive. Drive manufacturers use differing methods to configure their hardware and some drives have multiple configuration options.
IDE Cables
The PR5 comes with two IDE ribbon cables to connect
devices to the mainboard. Note that one edge of the cable
is colored to indicate the Pin 1 side. W hen you connect
the cable to the mainboard and a device you must orient
the cable so that this colored edge is at the Pin 1 side of
the connector you are plugging it on to.
The cables have three connectors on them, one at each
end and one in-between, closer to one of the ends. When
you install a drive, plug the end by itself onto one of the
onboard IDE connectors. The two connectors that are
closer to each other are for connecting to IDE devices.
The connector on the end is for the Master device and
the connector in the middle is for the Slave device.
Example IDE Configurations
Here are some basic installation procedures for example
hardware configurations. The position of the onboard IDE
connectors and their Pin 1 locations are shown below.
Onboard IDE Connectors
Pin 1
IDE1
IDE2
Example 1: One Hard Disk
To install this configuration:
1. Make sure the drive is configured as a master drive.
Most drives are set this way at the factory.
2. Connect the Master end of the IDE ribbon cable to
the drive aligning the Pin 1 positions and install it
in the system case.
3. Plug the other end of the IDE cable onto the IDE1
connector on the mainboard with the Pin 1 positions aligned.
4. Use the BIOS CMOS Setup Utility to enter the drive
parameters for the Primary Master as described in
the Standard CMOS Setup section of Section 3.
5. Format the drive as required by the operating system you will use.
Example 2: One Hard Disk & One CD-ROM Drive
To install this configuration:
1. Make sure the drives are configured as master
drives. Most hard disk drives are set this way at
the factory.
Alternate Installation
You can also install these as follows:
Hard Disk: Primary Master
Attach to end of 1st IDE cable.
CD-ROM: Primary Slave
Set drive as Slave.
Attach to middle of 1st IDE cable.
Attach other end of 1st IDE cable to PR5
IDE1 connector.
2. Connect the Master end of one IDE ribbon cable
to the hard disk aligning the Pin 1 positions and
install it in the system case.
3. Plug the other end of the IDE cable onto the IDE1
connector on the mainboard with the Pin 1 positions aligned.
4. Connect the Master end of the other IDE ribbon
cable to the CD-ROM drive aligning the Pin 1 positions and install it in the system case.
5. Plug the other end of the IDE cable onto the IDE2
connector on the mainboard with the Pin 1 positions aligned.
6. Use the BIOS CMOS Setup Utility to enter the hard
disk parameters for the Primary Master as described
in Standard CMOS Setup section of Section 3. The
CD-ROM drive does not require this.
7. Format the drive as required by the operating system you will use.
•
Note: You can also connect the CD-ROM drive as
the IDE1/Primary Slave but this can adversely affect hard disk performance. If you do , make sure
to configure the CD-ROM drive as a Slave drive.
Example 3: Two Hard Disks
To install this configuration:
1. Make sure one drive is configured as a Master drive
and the other as a Slave drive. Most drives are set
to Master at the factory.
Alternate Installation
You can also install these as follows:
Hard Disk 1: Primary Master
Set drive as Master.
Attach to end of 1st IDE cable, attach
other end to PR5 IDE1 connector.
Hard Disk 2: Secondary Master
Set drive as Master.
Attach to end of 2nd IDE cable, attach
other end to PR5 IDE2 connector.
2. Connect the Master end of the IDE ribbon cable to
the Master drive aligning the Pin 1 positions and
install it in the system case.
3. Install the Slave drive in the system case and connect the IDE ribbon cable’ s Slave connector to it,
aligning the Pin 1 positions.
4. Plug the other end of the IDE cable onto the IDE1
connector on the mainboard with the Pin 1 positions aligned.
4. Use the BIOS CMOS Setup Utility to enter the drive
parameters for the Primary Master and Primary
Slave as described in the Standard CMOS Setup
section of Section 3.
5. Format the drives as required by the operating system you will use. The Primary master is the boot
(start-up) drive.
Example 4: Two Hard Disks & One CD-ROM Drive
To install this configuration:
Alternate Installation
You can also install these as follows:
Hard Disk 1: Primary Master

BIOS Setup
W hen you install hard disk drives you must enter their
parameters in the Standard CMOS Setup section of the
BIOS CMOS Setup Utility as explained in Section 3. For
new drives you should use the IDE HDD Auto Detection
feature to automatically determine the drive parameters
and enter them in the required locations.
If you install a drive that has already been in use, you can
use the auto-detection feature with two considerations.
First, if you plan to reformat the drive, or second, if the
auto-detection feature comes up with the same parameters as the drive is already using.
Formatting With MS-DOS
To format and partition a hard disk drive
under MS-DOS, you use a utility provided called FDISK. If your drive is already formatted you don’t need to use
this. If you need to format a drive, the
procedure may vary depending on which
version of MS-DOS you are using. The
basic procedure is:
• Start the computer from a start-up
floppy disk. Type FDISK at the command
line and press Enter. This brings up the
program interface.
• At least one partition is required. You
can use the entire drive as one partition
or you can divide it into several. Create
a partition and make it Active. You must
have an Active partition or you can not
start up the computer from the hard
disk. For more information on FDISK
consult your MS-DOS documentation.
• After the disk is partitioned, depending on your DOS version, you may need
to manually format the partion(s). After the system restarts, type FORMAT
C: /S to format the C: drive. You must
use the /S switch or the system will
not be able to start up from this drive.
If you are going to reformat the drive, just use the autodetected parameters.
Some IDE hard drives can use more than one set of parameters. If you are not going to reformat the drive, you
must make sure the auto-detected parameters are correct. If they are correct, the drive will work properly, if
not, the system won’ t be able to access it. In this case,
you will need to enter the drive information manually.
IDE Hard Disk Formatting
IDE hard disk drives are formatted at two levels. They
are first low-level formatted and then they are formatted
as part of the operating system installation procedure.
Low level formatting is generally done by the drive manufacturer at the factory. Manufacturers often use proprietary low level formatting software, so not only is it generally unnecessary to use the HDD Low Level Format
feature of the BIOS CMOS Setup Utility, but it is also
inadvisable if the drive was formatted with proprietary
software. You should make sure this is not the case before you use this feature.
The second formatting procedure is part of installing the
operating system you will use and also involves partitioning the drive. Since this procedure varies depending
on the operating system, you should refer to the operating system documentation for formatting instructions.
Technical Support
In order to help solve any problems that might arise in
the course of using your PR5 mainboard we have included
a few troubleshooting guidelines and some pointers about
collecting information on your system to aid the technical support process. You should consult your vendor for
instructions on how to obtain technical support.
Troubleshooting Guidelines
Here are some basic troubleshooting guidelines that may
help you identify more specifically the cause of a hardware problem. Please note the information needed on the
Troubleshooting Form (you may want to make a copy of
the form and use that).
Scenario 1: We’ ll assume your system includes: the PR5
mainboard with CPU, DRAM and COAST cache module; hard drive, floppy drive, CD-ROM drive, display card,
MPEG card, SCSI card and sound card. If you have a problem, try the following procedures:
If the system won’ t start:
• Try installing another brand/model display card and see
if the system will start. If it does, please note the display
card model, mainboard model, CPU, BIOS identification
number and a description of the problem.
If the system will start:
• Remove all expansion cards except the display card.
Install the other expansion cards one at a time, and see if
the system will start after you install each card. If the
system won’ t start after you install a card, remove all the
other cards and try to start the system with just the display card and the card in doubt. If the system will not
start, please note the card information, mainboard model,
CPU, BIOS identification number and a description of
the problem.
Scenario 2: We’ ll assume your system includes: the PR5
mainboard with CPU, DRAM and COAST cache module; hard drive, floppy drive, CD-ROM drive, display card,
MPEG card, SCSI card, LAN card and sound card. If you
have a problem, try the following procedure:
If after installing the sound card driver the system automatically resets when it tries to load it:
• Try by passing the CONFIG.SYS and AUTOEXEC.BAT
files by holding down the Shift key during the “ Starting
MS-DOS” message.
You can then use a text editor to deactivate the sound
card driver in the CONFIG.SYS file. To do this, you must
find the line in the CONFIG.SYS file that loads the driver
and type REM and a space at the beginning of that line.
For example, using an example CONFIG.SYS file:
DEVICE=C:\DOS\HIMEM.SYS
DEVICE=C:\DOS\EMM386.EXE HIGHSCAN
DOS=HIGH,U MB
FILES=40
BUFFERS=36
REM DEVICEHIGH=C:\PLUGPLAY\DW CFGMG.SYS
LASTDRIVE=Z
If when you restart the system it no longer automatically
resets, you can probably assume that the problem is the
sound card driver. Please note the sound card and driver
version information, mainboard model, CPU, BIOS identification number and a description of the problem.
