Static Precautions
Static electricity can be a serious danger to the electronic components on this mainboard. To
avoid damage caused by electrostatic discharge, observe the following precautions:
üDon’t remove the mainboard from its anti-static packaging until you are ready to install
it into a computer case.
üBefore you handle the mainboard in any way, touch a grounded, anti-static surface, such
as an unpainted portion of the system chassis, for a few seconds to discharge any built-
up static electricity.
üHandle add-in cards and modules by the edges or mounting bracket.
Installing the CPU
üWARNING: Pentium Pro CPUs require a fan to keep
them cool and prevent overheating. Fans designed
specifically for the ZIF Socket 8 are recommended.
These fans provide a metal bracket that “snaps on” to
the tabs on the socket, holding the fan and CPU
firmly in place and preventing the CPU from working
loose during shipping. Other Fans should be installed first before inserting the CPU
into its socket.
1. Locate the ZIF (Zero Insertion Force) Socket 8. This socket supports Pentium Pro
CPUs (150-200Mhz).
2. First open the socket by pulling the lever sideways, then upwards. Notice how the lever
locks in place when pressed all the way down.
3. The CPU must be inserted with the correct orientation. One corner of the CPU has a
“notch” and looks different that the other three. This corner is marked with a white dot
on top of the CPU. Align this corner in the opposite direction of the lever as shown in
the figure above. Insert the CPU, hold it down, and close the lever until it locks into
place.
Connecting the CPU Cooling Fan (JP13)
JP13 is a small 3-pin Header Connector that provides 12-Volt power for CPU
Cooling Fans. This is useful if your Fan provides this type of connector,
instead of the normal Molex-Type Power-Supply connector. Pin-2
corresponds to the RED power lead as shown:

Setting the CPU Clock Selection Jumpers (JP3-5)
After installing the CPU, you must set
the clock selection jumper to match the
frequency of the CPU. Find the Jumper
Blocks labeled JP3-4 and JP5 on the
mainboard (Refer to the diagram on
page 7). Set the jumper according to the
table below for the CPU frequency you are using.
The CPU Clock corresponds to the number marked on the CPU. The Bus Clock when
multiplied with the Ratio gives the CPU Clock.

SETTING THE JUMPERSSETTING THE JUMPERS
P6F40-B5 User’s ManualP6F40-B5 User’s Manual 1111
Jumpers are used on this mainboard to
select various settings and features. A 2-pin
jumper has two settings: Open and Short (or
Closed). The jumper is closed by placing the
Jumper Cap across the two pins, thereby
connecting them. 3-pin jumpers can be set
to pins 1-2 or 2-3 connected. Pin-1 is
labeled on the circuit board for these jumpers as shown:
JP1: Super I/O Selection - [1-2] Enabled / [2-3] Disabled. The onboard Super-I/O
controller (W83877F) can be disabled to allow the use of an add-on I/O controller. Set JP1
to pins [2-3] to disable the onboard Floppy Controller, Serial Ports, Parallel Port, and IrDA
support.
JP2: PS/2 Mouse on IRQ12 - JP2 enables or disables the on-board PS/2 mouse lead
connector. When closed, the port becomes active and uses IRQ12.

Pins [3 & 5] Turbo LED switch - The Turbo function is
not supported by this mainboard. Therefore, the Turbo LED
will always remain lit as long as the system power is on.
Pins [7 & 9] SMI suspend switch lead - If your system’s
case has a suspend switch, hook the lead from the switch to
pins 7 & 9 of J15. A suspend switch is used to save
electricity by putting the system into a suspend mode when
the computer is not being used. This switch could also be
used by the Turbo switch on the front of the system, since
this mainboard does not support that function. For this switch to be functional, it must
first be enabled in the Power Management Setup in the BIOS Setup utility.
Pins [17 & 19] Reset switch lead - Connects to the Reset Switch lead from the system’s
case. The reset switch is used to “cold-boot” the system without actually turning off the
power, reducing wear and tear on the power supply.

Power Supply Cables
The two cables from the standard 5-volt power supply
connect to the power connector on the mainboard (refer
to page 4). You must align the connectors on the power
cable at a slight angle to correctly fit them onto the
mainboards power connector. Then, press down on the
connectors to lock them in place. The (2) connectors
should be installed so that the BLACK wires meet in
the middle of the connector.
Serial and Parallel Ports
The cables from the supplied serial port connector bracket hook to the COM1 and COM2
connectors on the mainboard. Generally, the upper serial port on the bracket would be
configured as COM1 and the lower port as COM2. Make sure to orient Pin-1 marked on the
mainboard to the RED stripe on the ribbon cables.
The cable from the supplied parallel port connector bracket hooks to the parallel connector
on the mainboard. Make sure to orient Pin-1 marked on the mainboard to the RED stripe on
the ribbon cable.
IrDA-compliant infrared module connector
The IrDA connector bracket hooks directly to this connector on the
mainboard. This connector provides support for the optional wireless
transmitting and receiving infrared module. You must first configure
through the BIOS setup where UART2 is directed, COM2 or IrDA.
USB Connector
This 8-pin connector permits connection of two USB peripheral devices directly to the
system without an external hub.

Keyboard Connector
This connection is for a standard IBM-compatible keyboard. May also be known as a 101
enhanced keyboard.
PS/2 Mouse Connector
If you are using a PS/2 mouse, you must purchase one bracket to
insert into your PC and a single customized cable to directly
connect to the PS/2 mouse pin-header on your mainboard.
Floppy drives
The on-board floppy controller supports (2) floppy disk drives with the floppy ribbon cable
provided. Make sure the RED stripe on the ribbon cable is oriented towards Pin-1. Notice
the “twist” between the sets of connectors on the floppy cable. The floppy drive “A”
position is at the END of the cable, whereas floppy drive “B” is hooked to one of the
connectors on the other side of the twist. The cable provides both “Edge” and “Pin”
connectors for both the A and B positions to match the connector on your floppy drives.
IDE Hard Drives and CD-ROMs
The on-board Enhanced IDE controller can support up to (4) IDE hard drives or other
ATAPI devices, such as CD-ROMs. This controller, as with all Enhanced IDE controllers,
consists of both Primary and Secondary ports. Each port has an associated connector and
cable which can support up to (2) ATAPI devices each.
All IDE devices have jumpers which allow the user to configure the device as either
“Master” or “Slave”. A Master device is one that is ALONE on the IDE cable, whereas a
Slave device is installed as a SECOND device on the same cable. Keep in mind that the
Master device will appear before the Slave device in the CMOS Setup, as well as the
Operating System software. *Refer to the device documentation for jumper settings.
The Secondary IDE port can be used for up to (2) additional ATAPI devices. Normally it’s
recommended that you connect your first hard drive to the Primary port, and the first CD-
ROM to the Secondary.
Make sure to align the RED stripe on the ribbon cable with Pin-1 on the mainboard IDE
connector. On most hard drives and CD-ROMs, the RED stripe should be oriented towards
the power connector of the device.

MAINBOARD BIOS SETUPMAINBOARD BIOS SETUP
P6F40-B5 User’s ManualP6F40-B5 User’s Manual 1515
About the BIOS
The Mainboard BIOS (Basic Input/Output System) acts as the bridge between your
Hardware (CPU, Disk Drives, Video, etc.) and Operating System Software (Windows 95,
OS/2 and so on…) The BIOS Setup (also called CMOS Setup) is where many hardware
configuration options are set and stored. This configuration information will remain in the
BIOS until it is changed, or cleared via the “Clear CMOS” jumper (see page 12).
CMOS (Complementary Metal Oxide Semiconductor) refers to the chip in which the BIOS
information is stored.
The P6F40-B5 mainboard features Award BIOS, which provides an easy to use Setup
program to aid in hardware configuration. In this section we will look at the various menus
and options contained in the Award BIOS Setup Program. This mainboard also features a
“Flash” BIOS. A Flash BIOS can be upgraded via software, thereby eliminating the need to
actually replace the “BIOS Chip” on the mainboard. Procedures for updating the BIOS
follow this section.
The Award BIOS installed in your computer system’s ROM (Read Only Memory) is a
custom version of an industry standard BIOS. This means that it supports Intel/Cyrix/AMD
processors in a standard IBM-AT compatible input/output system.
Using Setup
In general, you use the arrow keys to highlight items, press <Enter> to select, use the
PageUp and PageDown keys to change entries, press <F1> for help and press <Esc> to quit.
Getting Help
Pressing F1 will display a small help window that describes the appropriate keys to use and
the possible selections for the highlighted item. To exit the Help Window press <Esc>.
A Final Note About Setup
Not all systems have the same Setup. While the basic look and function of the Setup
program remains the same for all systems, individual motherboard and chipset combinations
require custom configurations. For example, you may find that your Setup main menu has a
different number of entries from the main menu displayed in this manual. These are simply
features not supported (or not user configurable) on your system.
The final appearance of the Setup program also depends on the Original Equipment
Manufacturer (OEM) who built your system. If your OEM has decided that certain items
should only be available to their technicians, those items may very well be removed from
the Setup program.

Upon entering the Standard CMOS Setup screen, you will see a screen like that below.
Again, notice that the bottom of the screen provides information relating to the highlighted
item as you move around the screen.
First, let’s set the system Date. Use the arrow keys to move to and highlight the “Date”
option. Select the Month by using the PgDn and PgUp keys. This is how most settings will
be configured. Then, move to the day, year and time via the arrow keys to finish setting the
system date and time.
Keep in mind that the system time is set in 24-hour time. With this method, 1PM is
represented as 13:00, 2PM as 14:00 and so on, with 00:00 corresponding to Midnight.
Pri Master, Pri Slave, Sec Master, Sec Slave - These four options relate to the (4) IDE
hard drives, CD-ROMs or other ATAPI devices that can be controlled via the on-board IDE
controller (review IDE Hard Drives and CD-ROMs on page 14). The “Pri Master” setting
specifies the first device on the primary IDE channel, “Pri Slave” - the second. Sec Master
and Sec Slave specify the devices on the secondary channel.
The first option available is the most important: Type. This is where you will specify the
type of device and how it is represented in the BIOS Setup. If the device is a hard disk or

CD-ROM, generally the Auto option is the best choice for fast and easy setup of the hard
disk parameters. Let’s take a look at the difference between the Auto, User and Types (1-
45) options:
•Auto - This option instructs the BIOS to automatically configure the hard disk by
reading the parameters (cylinders, sectors, etc.) directly from the hard disk’s firmware.
Use this option if you are configuring a new hard drive, or one that has already been
formatted using the Auto option. Keep in mind that a hard drive is configured using a
certain set of parameters, those same parameters must be used for the life of the drive,
unless the drive is re-FDISKed using a different parameter set. (This procedure deletes
the old partition(s) on the drive and creates a new one, using the new parameters).
•User - This option allows you to manually
enter in the parameters of the hard drive.
Generally, this option would be used only if
the hard drive has already been formatted
with a certain set of parameters, and assured
consistency between the old and new
parameters is desired.
•Types 1-45 - Similar to the User option, these types should only be used if the exact
parameters for the hard drive are already entered as a specific type stored in the Setup
Program. Again, this would only be needed to assure that the parameters the drive was
formatted with and those it is using now, are identical. For new hard drives, the Auto
option is the preferred choice.
Mode - One of Enhanced IDE’s most important features is LBA (Logical Block Addressing)
Mode. This feature allows the use of larger hard drives by providing a way to bypass the
cylinder limitations imposed by many Operating Systems. LBA Mode is used to extend a
hard drive’s useable capacity by “remapping” the cylinders in a way that is acceptable to
these operating systems. For instance, a hard drive with the parameters of 2100 Cylinders,
16 Heads and 63 Sectors would be represented by LBA Mode as 525 Cylinders, 64 Heads
and 63 Sectors. (Notice that the Cylinders have been divided, and the Heads have been
multiplied, by a factor of 4)
On hard drives smaller in capacity than 528MB, LBA support is not needed. The option on
these devices is ignored, even if enabled. For hard drives greater than 528MB, LBA mode
should be enabled. The following rules apply:
•Operating Systems that do not use the FAT file system do not need LBA Mode, and
can use the Normal or Large Modes. Examples would be Netware and Unix.
•When configuring a new hard drive greater than 528MB in capacity, always make sure
LBA mode is enabled.

•If you are using a hard drive that is over 528MB in capacity, but was already formatted
without using LBA mode, LBA support will be ignored even if it is enabled. This
assures correct access to the drive’s data.
•SCSI Hard Drives are NOT entered into the Mainboard BIOS Setup in any way.
The hard drive settings in the Standard CMOS Setup are only for drives connected to
the IDE Controller. So, if only SCSI drives were installed, all these settings would be
set to Type: None. SCSI Devices are configured via the SCSI controller’s BIOS.
Floppy Drives A: and B: - Select the Type for the A: and/or B: floppy drives. Remember,
floppy drive A: is the first drive, hooked to the END of the floppy ribbon cable. Floppy drive
B: is hooked up after the twist. Available settings are listed below:

Base Memory is the amount of conventional memory installed in the system. This value is
typically 640K for systems with 640K or more memory installed on the motherboard. The
Extended Memory is the amount of memory located above 1MB in the CPU's memory
address map. Other Memory refers to the memory located in the region between 640K and
1MB. This region can be used for shadowing as well as expanded memory in DOS.

Virus Warning - When enabled, the BIOS will warn the user when any program attempts
to write to or format the boot sector. If an
attempt is made, the BIOS will halt the
system and the following error message
will appear:
You can accept or abort this operation.
Note: This feature is designed to guard against viruses that modify the boot sector on hard
disks. However, many disk diagnostic programs which attempt to access the boot sector
table, as well as partition and format programs, will also trigger this warning. If you will be
running such a program, you can disable Virus Protection first, or choose “Y” to accept the
boot sector modification when this message shows up.
! WARNING !
Disk boot sector is to be modified
Type "Y" to accept write or "N" to abort write
