INSTALLATIONINSTALLATION

Setting the Jumpers

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 2­3 connected. Pin-1 is labeled on the circuit
board.

Setting the CPU Clock Selection Jumper (JP5)

After installing the CPU, you must set the
clock selection jumper to match the frequency
of the CPU. Find the Jumper Block labeled
JP5 on the mainboard. Set the jumper
according to the table at right 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.

üü For a dual CPU system: It is recommended that you use two identical CPUs in your

system. If your CPUs have different speed requirements, you must set the CPU Clock
Selection Jumper Block to the lower frequency.

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 CD­ROM 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.

Installing the Memory (DIMM)

• The P6B40D-A5 mainboard has four sockets available for 168-pin DIMMs. They must

be 3.3 volt Unbuffered Synchronous DRAMs (SDRAM) or 3.3 volt EDO RAM.

For using SDRAMs:

• If you are using a CPU with a 100MHz system bus, you can use only the

100MHz (-10 ns) or faster SDRAMs.

• If you are using a CPU with a 66MHz system bus, you can use either the 66

MHz or 100MHz SDRAMs, or mix them both.

• DIMM Sizes supported: 8MB, 16MB, 32MB, 64MB, 128MB, and 256MB

• A total of (4) DIMMs can be installed for a maximum RAM capacity of 1 GB.

To insert the DIMMs, the modules must be oriented in the correct way. Notice the notches

of the DIMM. Align these notches as shown in the diagram below. Gently push the DIMM
until the retainers on both sides of the socket lock the module in place. To remove a DIMM,

MAINBOARD BIOS SETUP

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 by removing the battery for a while then reinstalling it
back.

CMOS (Complementary Metal Oxide Semiconductor) refers to the chip in which the BIOS

information is stored.

The P6B40D-A5 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 processor 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.

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.

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 19). 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:

P6B40D-A5 User’s ManualP6B40D-A5 User’s Manual

MAINBOARD BIOS SETUPMAINBOARD BIOS SETUP

• 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

Quick Power on Self Test - Speeds up Power On Self Test (POST) after the computer is

powered on. When set to Enabled, the BIOS will shorten or skip some checks during
POST.

Hard Disk Boot From - This option lets you choose to boot from Primary IDE Master (Pri-

IDE-M), Primary IDE Slave (Pri-IDE-S), Secondary IDE Master (Sec-IDE-M), Secondary
IDE Slave (Sec-IDE-S), or SCSI hard disk. Same as IDE options, the Boot Sequence in the
next field is set to C, A when the SCSI is chosen.

Boot Sequence - When your system is powered on, the BIOS performs a variety of

operations, then attempts to boot an Operating System from either a hard drive, floppy
drive, CD-ROM or LS-120/ZIP. This setting determines the sequence that the BIOS will
follow when searching devices for a bootable disk. Most users find the C, A setting to be
most beneficial, since it takes the least amount of time to boot the system. If however, you
want the ability to boot from a Floppy or CD-ROM drive, you would need to choose either
the A, C or CDROM, C, A setting. For instance, if your boot sequence was set to C, A and
for some reason you wanted to boot to your Floppy A: Drive, it would not be possible, since
the BIOS would always boot from the C: drive first. In this case, this setting would need to
be changed to A, C so that the system would first check the floppy drive for a bootable disk.
This would slow bootup speed, however, since the floppy would be checked on every boot.

A,C System will first search for boot sector on floppy disk, then hard disk.
C, A System will first search hard disk drive then floppy disk drive for boot sector.
C, CDROM, A System will first search for boot sector on hard disk drive , then CDROM drive,

CDROM, C, A System will first search the CDROM drive, then hard disk drive and then floppy
C only System will search for boot sector on hard disk drive only.

LS/ZIP, C System will first search for boot sector on LS-120 IDE floppy drive or ZIP ATAPI

Swap Floppy Drive - The hardware connections determine which floppy is configured as

drive A: and drive B: “Swapping” the floppy drives can be useful if your system has two
floppy drives, and you want the ability to boot from both. For example: Since a PC cannot
boot from the B: Floppy, you would need to “Swap” floppy drives A: and B: in order to set
the second floppy drive to drive A:, thereby making it bootable.

Boot Up Floppy Seek - When enabled, BIOS will attempt to move the head of the floppy

disk drive forth and back once during POST to see if the drive is working properly.

Boot Up NumLock Status - When On, the NumLock key will be automatically enabled

when the system boots.

Typematic Rate Setting - Determines if the typematic rate is to be used. When disabled,

continually holding down a key on your keyboard will generate only one instance. In other
words, the BIOS will only report that the key is down. When the typematic rate is enabled,
the BIOS will report as before, but it will then wait a moment, and, if the key is still down,
it will begin to report that the key has been depressed repeatedly. This feature is used to
accelerate cursor movements with the arrow keys.

Typematic Rate (Chars/Sec) - When the typematic rate is enabled, this selection allows

you to select the rate at which the keys are accelerated: Options are 6 (default), 8, 10, 12,
15, 20, 24 and 30.

Typematic Delay (Msec) - When the typematic rate is enabled, this selection allows you to

select the delay (in msec) between when the key was first depressed and when the
acceleration begins. Options are 250 (default), 500, 750 and 1000.

Security Option - This option enables password checking every time the computer is

powered on or every time BIOS Setup is executed. If System is chosen, a user password
prompt appears every time the computer is turned on. If Setup is chosen, the password
prompt appears only when the BIOS Setup program is executed. Refer to the section
Supervisor Password for more information.

PCI / VGA Palette Snoop - This option must be set to Enabled if any ISA MPEG card

installed requires VGA palette snooping. The settings are Disabled or Enabled.

Assign IRQ For VGA - The Enabled option allows the BIOS to auto-route an IRQ for use

by a VGA card. While most of the VGA cards do not need an IRQ assignment, certain VGA
cards may need it.

MPS Version Control For OS - Normally your OS should support Multiple Processor

Specifications version 1.4. If your OS only support version 1.1, set this option to 1.1.

OS Select For DRAM > 64MB - This should be set to OS2 if you are running IBM OS/2

with more than 64MB of RAM in the system. Otherwise, the setting should be Non-OS2.

HDD S.M.A.R.T. Capability - The default is Disabled. If you are using hard drives that

support S.M.A.R.T., set this field to Enabled. SMART (Self-Monitoring, Analysis and
Reporting Technology) is a reliability prediction technology for ATA/IDE and SCSI drives.
The drive will provide sufficient notice to the system or user to backup data prior to the
drive’s failure. SMART is supported in ATA-3 or later hard drives.

Report No FDD For WIN95 - While the FDD in “STANDARD CMOS SETUP” is set to

NONE, set this option to No to release IRQ6 for passing Win95 logo. This option is
irrelevant under normal operation.

DRAM Data Integrity Mode - When set at Non-ECC (default), there will be no memory

errors shown on the monitor for Memory parity SERR# (NMI). When parity DRAM
modules are used, select ECC (Error Checking and Correcting) to correct 1-bit memory
errors in the memory.

System BIOS Cacheable - When Enabled, the contents of the F0000h system memory

segment can be cached to the Level-2 cache memory. The contents of the F0000h memory
segment are always copied from the BIOS ROM to system RAM for faster execution and
PCI compliance.

Video RAM Cacheable - Enabled will cause access to the video RAM addressed at

B0000H to BFFFH to be cacheable and also let the A0000H to AFFFFH to be a UC memory
type.

8 Bit I/O Recovery Time - The recovery time is the length of time, measured in ISA BUS

clocks, that the system will delay after the completion of an input/output request. This delay
takes place because the CPU is operating faster than the input/output bus. Therefore the
CPU must be delayed to allow for the completion of I/O transfers. This item allows you to
determine the recovery time allowed for 8 bit I/O. Choices are from NA, 1 to 8 ISA BUS
clocks. *1 is the default.

16 Bit I/O Recovery Time - This item allows you to determine the recovery time allowed

for 16 bit I/O. Choices are from NA, 1 to 4 ISA BUS clocks. *1 is the default.

Memory Hole At 15M-16M - In order to improve compatibility, certain space in memory

can be reserved for old style ISA cards that map memory between 15M-16M. Do not enable
this feature unless you use the old style ISA card, otherwise the memory size may be
reduced to 15 MB for some O.S. *Disabled is the default.

Passive Release - The PIIX4 provides a programmable Passive Release mechanism to meet

the required master latencies. When enabled (default), ISA masters may see long delays in
access to any PCI memory, including the main DRAM array.

Delayed Transaction - When enabled, the delay transaction mechanism will be in effect

when PIIX4 is the target of a PCI transaction.

AGP Aperture Size (MB) - Select the size of the Accelerated Graphics Port (AGP)

aperture. The aperture is a portion of the PCI memory address range dedicated for graphics

PNP/PCI Configuration Setup
The PCI Personal Component Interconnect Bus was developed by Intel and other industry

leader partners primarily to address two important issues faced by PC hardware designers
today: a) How to allow peripheral devices to take the fullest advantage of the power of
Pentium and Pentium Pro chip technology, and b) Provide a simpler installation process for
peripheral devices, such as Network cards, EIDE or SCSI controllers.

PCI accomplishes these goals with its 32-bit Data path Local Bus design, and support for

Plug & Play. Unlike older expansion bus architectures, PCI provides peripherals with a
direct connection to the CPU and memory. The PCI bus runs at 33Mhz and has a maximum
transfer capability of 132MBps. With Plug & Play, the system BIOS automatically
determines hardware resources for new peripherals, simplifying installation of multiple
interface cards.

assigned to the PCI Bus. If an ISA card requires a particular IRQ or DMA channel, those
resources should be set to Legacy ISA so that the PCI Bus will not try to use them. Choices
are Legacy ISA and PCI/ISA PnP.

Assign IRQ For USB - When Enabled, the system automatically assigns an IRQ for the

USB device connected to your system. However, if you are not using USB devices and an
ISA slot requires an IRQ address, set this function to Disabled. The IRQ address previously
occupied by the USB device will be available for the ISA slot.

Used MEM base address - This item allows you to determine which basic addresses are

not to be occupied by PCI Card and leave these addresses for some special ISA Card used
only.

Supervisor Password and User Password Setting

Passwords can be set to provide protection for the BIOS configuration options, or to restrict
access to the computer itself.

When enabled, User Password will require all users to enter a password in order to use the
system, and/or enter the BIOS setup (but can’t change its contents). A Supervisor Password
is used to protect the stored CMOS options from being changed by unauthorized users.

Keep in mind that when set, a password is required only when booting the system. It will
not provide protection to a system that is already booted.

The password check option is set in BIOS FEATURES SETUP by choosing either System
(the password prompt appears every time the system is powered on) or Setup (the password
prompt appears only when the user enters the BIOS Setup). The password is stored in
CMOS RAM, and can be cleared by removing the battery for a while and then re-installing
it back.

To set a password:

1. You must first set the Supervisor password by choosing Supervisor Password and

pressing [ENTER]. Setup prompts for a password.

2. Enter a 1-8 character password using letters, numbers, or a combination of both. The

specific characters are not shown as you enter them. Press [ENTER].

3. A confirmation box appears asking you to re-enter the password. Enter the password

again. Press [ENTER]. Follow the same procedure to set the User Password.

Changing a Password:

1. Select the appropriate password option (Supervisor or User) from the main menu and

press [ENTER]. Enter the current password and press [Enter]. The screen does not
display the characters entered. Enter in the new password, then the confirmation. You
cannot change the current password unless you know it.

Erasing a Password:

1. If you know the current password, but want to disable password checking, follow the

procedure for changing the password. When Setup prompts for the new password,
simply press [ENTER]. You will see a message indicating that the password is
disabled.

2. If you do not know the current password, the CMOS must be cleared by removing the

battery for a while and then re-installing it back. *This will clear all user-defined BIOS
Setup options.

SCAM Support - SCAM (SCSI Configured AutoMatically) is the SCSI Plug and Play

protocol supported by Symbios BIOS version 4.X.

Parity - The Symbios host adapters always generate parity, but some SCSI devices do not.

Therefore, you are offered the option of disabling parity checking.

Note: When disabling parity checking, it is also necessary to disable disconnect for all

devices, as parity checking for the reselection phase will not be disabled. If a device
does not supporting parity disconnects, the I/O will never complete because the
reselection phase will halt.

Host SCSI ID - The host adapter SCSI ID should remain on 7 (default), as this setting gives

the adapter the highest priority on the SCSI bus. However, if you have two adapters on
the same SCSI bus, you should give one of them an unassigned ID to avoid duplication
of SCSI IDs.

Scan Order - This option allows you to tell the host adapter BIOS and your device drivers

to scan the SCSI bus from low to high (0 to max) SCSI IDs, or from high to low (max
to 0) SCSI IDs. If you have more than one device on the SCSI bus, changing the scan
order changes the order in which drive letters are assigned by the system.

Removable Media Support - Determine if the removable media will be used as BIOS

device. A BIOS device here is a device that can be controlled via BIOS INT 13H, i.e. it
does not need a device driver and can be bootable. However, when used as a BIOS
device, the full removability of removable media devices is not preserved. The
following constraints apply:
a) The device can only work as a fixed disk, i.e. media change is not allowed.
b) The media must be inserted before the system boot-up.

Sync Rate (Mega Bytes/sec) - Defines the maximum transfer rate the host adapter attempts
to negotiate. The host adapter and a SCSI device must agree to a rate they can both handle.

Width (bits) - Sets the maximum data width the host adapter will attempt to negotiate. The
host adapter and a SCSI device must agree to a width they can both handle. Only those host
adapters that support 16 bit data transfers will show this option as enabled.

Disconnect - SCSI devices have the ability to disconnect from the bus during an I/O
transfer. This option tells the host adapter whether or not to allow a device to disconnect.
Some devices run faster with disconnect enabled (mostly newer devices), while some run
faster with disconnect disabled (mostly older devices).

Read Write I/O Timeout (secs) - This option sets the time the host adapter waits for a
read, write, verify, or seek command to complete before trying the I/O transfer again. Since
this provides a safeguard allowing the system to recover if an I/O operation fails, it is
recommended that you always set the time-out to a value greater than zero (no time-out).

Scan for Device at Boot Time - When there is a device you do not wish to make available
to the system, set this option to No for that device. Also, on a bus with only a few devices
attached, you can speed up boot time by changing this setting to No for unused SCSI IDs.

Scan for SCSI LUNs - You can set this option to No if you have problems with a device
that responds to all LUNs whether they are occupied or not.

Queue Tags - If your device driver can issue queue tags, this option allows you to enable or
disable the issuing of queue tags during I/O requests.

Format Device - Low level format the selected device. All information on the drive will be
erased.

FLASH BIOS PROGRAMMING UTILITY

Updating the Award BIOS Code is made easy with the AWDFLASH Utility. Since this
mainboard features FLASH BIOS, it is not necessary to change the actual BIOS chip in
order to upgrade the System BIOS. The user can simply re-program the old BIOS using the
AWDFLASH Utility as follows:

1. First, boot the system with DOS or to “Safe Mode” under Windows 95. If you are

booting DOS from a hard drive or floppy disk, press [F5] when the message “Starting
MS-DOS…” appears on the screen. If you are booting Windows 95, press the [F8] key,
and select the “Safe mode command prompt” option. This will assure that the system is
running in “real mode” with no device drivers loaded. This is the only correct way to

run the AWDFLASH Utility program.

2. There are (2) important files needed to re-program the BIOS. The first is

“AWDFLASH.EXE” which is the FLASH BIOS Programming Utility. The second file
needed is the updated “BIN” file which contains the actual BIOS code. This file will
have the extension [.bin], such as “P598GH.BIN”. Make sure these files are on the
diskette or hard drive in the same directory.

3. Start the AWDFLASH Utility by changing to the directory where the two required files

exist and typing: AWDFLASH and pressing [ENTER].

4. The AWDFLASH Utility Screen appears. You will be asked for the file name to

program. Type in the name of the new BIOS (.bin) file and hit [ENTER].

5. The program will then ask if you want to backup the old BIOS. This is recommended in

case there are any problems with the new “.bin” file. Enter the name of the new backup
file (such as “backup.bin”) and press [ENTER].

6. At this time the system will prompt you for final confirmation before beginning

programming. The Utility can be aborted at this time by hitting “n”. To begin
programming, hit “y”…

7. When the Flash programming starts, a bar indicator will show the progress of the

programming operation. After successful completion, hit the reset button or power off
the computer.
