Precaution Before Start

Static Electricity Damage:

Static electricity can easily damage your motherboard. Observing
a few basic precautions can help safeguard against damage that
could result in expensive repairs. Follow the simple measures
below to protect your equipment from static electricity damage:

1. Keep the motherboard and other system components in their anti-static

packaging until you are ready to install them.

2. Touch a grounded surface before you remove any system component from

its protective anti-static packaging. Unpacking and installation should be
done on a grounded, anti-static mat. The operator should be wearing an anti­static wristband, grounded at the same points as the anti-static mat.

3. After removing the motherboard from its original packaging, only place it

on a grounded, anti-static surface component side up. Immediately inspect
the board for damage. Due to shifting during shipping, it is suggested that
the installer press down on the entire socket ICs to ensure they are properly
seated. Do this only with the board placed on a firm flat surface.

4. During configuration and installation touch a grounded surface frequently

to discharge any static electrical charge that may have built up in your body.
The best precaution is to wear a grounded wrist strap. When handling the
motherboard or an adapter card avoids touching its components. Handle the
motherboard and adapter cards either by the edges or by the adapter card
case-mounting bracket.

Misplaced Jumper Damage:

There are critical headers used for connectors or power sources.
These are clearly marked separately from the jumpers listed in
Motherboard Layout. Incorrectly setting jumpers and connectors
may lead to damage to your motherboard. Please pay special
attention not to connect these headers in wrong directions.

requires a PCI add-in network interface card (NIC) with remote wakeup
capabilities. The remote wakeup header on the NIC must be connected to the
onboard Wake on LAN header. For Wake on LAN, the 5-V standby line for the
power supply must be capable of delivering 5V±5% at 720mA.

Chassis Fan

This header can supply power for Chassis Fan which may be mounted inside your
case to cool down your system components. If your chassis have a Chassis Fan,
this header will support it.

Infrared (IrDA) connector (6-pin)

The VP1541 offers an IrDA infrared header that supports third party infrared
modules. The case must reserve space for the IR module if you want to use the
IrDA function. This option supports wireless transmission and reception of
infrared data. The module mounts in a small opening on the system case that
supports this feature. The efficient distance is 100cm and the transfer rate is
115,200 bits/sec.

CPU Fan

Your Pentium Cartridge may have an attached heatsink and Fan; this connector is
for the CPU Fan.

♦ Check Again

1. Is the CPU installed exactly and firmly into socket (Sec.

3.2)?

2. Are all the DRAM modules installed properly (Sec. 3.3)?

3. Did you insert expansion card (VGA, Sound…. etc.)
already (Sec. 3.4)?

4. Are you sure that all the connectors (described in Sec 3.5)
have been connected to their variable devices (Sec. 3.5)?

♦ Yes, I have checked and assured the above steps!

Now get ready to turn on your device by the following steps.

1. Mount your motherboard to the chassis frame and close the
case cover.

2. Switch off all power.

3. Connect the power supply cord into inlet of the system
case.

4. Connect the power supply cord into an outlet of power

The VP1541 motherboard uses AWARD
BIOS, which is stored in a Flash EEPROM
and can be upgraded by a floppy disk-based
program. The BIIOS has a built-in Setup
Program that allows users to modify the
basic system configuration settings. The
settings are then stored in a dedicated
battery-backed memory, called CMOS
RAM that retains the information when the

power is turned off. The BIOS provides
critical low-level support for the system’s central processing, memory and I/O
subsystems. The AWARD BIOS has been customized by adding important,
nonstandard, features such as virus and password protection, power management, and
detailed fine-tuning of the chipset which controls the system. The remainder of this
manual is intended to guide you through the process of configuring your system using
the BIOS Setup.

4.1 How To Enter BIOS Setup

The AWARD BIOS is immediately activated when you first turn on the computer. The
BIOS reads system configuration information in CMOS RAM and begins the process of
checking the system and configuring it through the power-on self test (POST). When
these preliminaries are finished, the BIOS seek an operation system on the data storage
devices (hard drive, floppy drive, etc.). The BIOS launches the operating system and
hands over control of system operation to it.

To start Setup, press the <Del> key during boot-up before or while a message similar
to this appears briefly at the bottom of the screen during POST (Power On Self Test):

Press DEL if you want to enter SETUP

If the above message disappears before you have responded and you still wish to enter
Setup, reboot the system to try again by pressing the “RESET” button on the system
case. You may also restart by simultaneously pressing the <Ctrl>, <Alt> and <Delete>
keys.

Press F1 to continue, DEL to enter SETUP

the F1 key again.

4.1.3 In Case of Problems

If after making and saving system changes with Setup, you discover that your computer
no longer is able to boot, the Award BIOS supports an override to the CMOS settings
that resets your system to its default configuration.

The best advice is to alter only settings that you thoroughly understand. In particular,
do
not change settings in the Chipset screen without a good reason. Your system
manufacturer for the best performance and reliability has carefully chosen the Chipset
defaults. Even a seemingly small change to the Chipset setup may cause the system to
become unstable.

Date

The BIOS determines the day of the week from the other date information. This field is
for information only. Press the left or right arrow key to move to the desired field (date,
month, year). Press the PgUp or PgDn key to increment the setting, or type the desired
value into the field.

Time

The time format is based on the 24-hour military-time clock. For example, 1 p.m. is
13:00:00. Press the left or right arrow key to move to the desired field. Press the PgUp
or PgDn key to increment the setting, or type the desired value into the field.

Hard Disks

The BIOS supports up to four IDE drives. This section does not show information
about other IDE devices, such as a CD-ROM drive, or about other hard drive types,
such as SCSI drives.

39

NOTE: We recommend that you select type AUTO for all drives.

The BIOS can automatically detect the specifications and optimal operating mode of
almost all IDE hard drives. When you select type AUTO for a hard drive, the BIOS
detects its specifications during POST, every time the system boots.

If you do not want to select drive type AUTO, other methods of selecting the drive type
are available:

1) Match the specifications of your installed IDE hard drive(s) with the

preprogrammed values for drive types 1 through 45.

2) Select USER and enter values into each drive parameter field.

3) Use the IDE HDD AUTO DECTECTION function in Setup.
Here is a brief explanation of drive specifications:

• Type: The BIOS contains a table of pre-defined drive types. Each defined drive

type has a specified number of cylinders, number of heads, write
precompensation factor, landing zone, and number of sectors. Drives whose
specifications do not accommodate any pre-defined type are classified as type
USER.

• Size: Disk drive capacity (approximate). Note that this size is usually slightly

greater than the size of a formatted disk given by a disk-checking program.

• Cyls: Number of cylinders

• Head: Number of heads

• Precomp: Write precompensation cylinder

• Landz: Landing zone

• Sector: Number of sectors

• Mode: Auto, Normal, large, or LBA

• Auto: The BIOS automatically determines the optimal mode.

• Normal: Maximum number of cylinders, heads, and sectors supported are 1024,

16, and 63.

• Large: For drives that do not support LBA and have more than 1024 cylinders.

• LBA (Logical Block Addressing): During drive accesses, the IDE controller

transforms the data address described by sector, head, and cylinder number into a
physical block address, significantly improving data transfer rates. For drives

40

with greater than 1024 cylinders.

Drive A/B type

Select the correct specifications for the diskette drive(s) installed in the computer.

None No diskette drive installed

360K, 5.25 in 5-1/4 inch PC-type standard drive; 360 kilobyte capacity

1.2M, 5.25 in 5-1/4 inch AT-type high-density drive; 1.2 megabyte capacity
720K, 3.5 in 3-1/2 inch double-sided drive; 720 kilobyte capacity

1.44M, 3.5 in 3-1/2 inch double-sided drive; 1.44 megabyte capacity

2.88M, 3.5 in 3-1/2 inch double-sided drive; 2.88 megabyte capacity

Video

Select the type of primary video subsystem in your computer. The BIOS usually detects
the correct video type automatically. The BIOS supports a secondary video subsystem,
but you do not select it in Setup.

EGA/VGAEnhanced Graphics Adapter/Video Graphics Array. For EGA, VGA,

SEGA, SVGA or PGA monitor adapters.
CGA 40 Color Graphics Adapter, power up in 40 column mode.
CGA 80 Color Graphics Adapter, power up in 80 column mode.

MONO Monochrome adapter, includes high resolution monochrome adapters.

Halt on

During the power-on self-test (POST), the computer stops if the BIOS detects a
hardware error. You can tell the BIOS to ignore certain errors during POST and
continue the boot-up process. These are the selections:

No errors POST does not stop for any errors.
All errors

All, But keyboard

All, But Diskette

All, But Disk/Key

If the BIOS detects any non-fatal error, POST stops and
prompts you to take corrective action.
POST does not stop for a keyboard error, but stops for all
other errors.
POST does not stop for diskette drive errors, but stops for all
other errors.
POST does not stop for a keyboard or disk error, but stops for
all other errors.

41

Memory

You cannot change any values in the Memory fields; they are only for your information.
The fields show the total installed random access memory (RAM) and amounts
allocated to base memory, extended memory, and other (high) memory. RAM is
counted in kilobytes (KB: approximately one thousand bytes) and megabytes (MB:
approximately one million bytes).

RAM is the computer's working memory, where the computer stores programs and data
currently being used, so they are accessible to the CPU. Modern personal computers
may contain up to 64 MB, 128 MB, or more.

Base Memory

Typically 640 KB. Also called conventional memory. The DOS operating system
and conventional applications use this area.

Extended Memory

Above the 1-MB boundary. Early IBM personal computers could not use memory
above 1 MB, but current PCs and their software can use extended memory.

Other Memory

Between 640 KB and 1 MB; often called High memory. DOS may load terminate­and-stay-resident (TSR) programs, such as device drivers, in this area, to free as
much conventional memory as possible for applications. Lines in your
CONFIG.SYS file that start with LOADHIGH load programs into high memory.

Total Memory

System total memory is the sum of base memory, extended memory, and other
memory.

should then run an anti-virus program. Keep in mind that this feature protects only the
boot sector, not the entire hard drive.

NOTE: Many disk diagnostic programs that access the boot sector table can trigger the
virus warning message. If you plan to run such a program, we recommend that you first
disable the virus warning.

CPU Internal Cache

Cache memory is additional memory that is much faster than conventional DRAM
(system memory). Some CPU integrate a build-in Cache memory to speed up the data
transfer. This item allows you to enable or disable the inter Cache.

External Cache

Cache memory is additional memory that is much faster than conventional DRAM

43

(system memory). When the CPU requests data, the system transfers the requested data
from the main DRAM into cache memory, for even faster access by the CPU. The
External Cache field may not appear if your system does not have external cache
memory.

Quick Power On Self Test

This allows you to enable or disable system self test when power on.

Boot Sequence

The original IBM PCs loaded the DOS operating system from drive A (floppy disk), so
IBM PC-compatible systems are designed to search for an operating system first on
drive A, and then on drive C (hard disk). However, the BIOS now offers 10 different
boot sequence options of three drives each. In addition to the traditional drives A and
C, options include IDE hard drives D, E, and F; plus a SCSI hard drive and a CD-ROM
drive.

Swap Floppy Drive

This field is effective only in systems with two floppy drives. Selecting Enabled
assigns physical drive B to logical drive A, and physical drive A to logical drive B.

Boot Up Floppy Seek

When Enabled, the BIOS tests (seeks) floppy drives to determine whether they have 40
or 80 tracks. Only 360-KB floppy drives have 40 tracks; drives with 720 KB, 1.2 MB,
and 1.44 MB capacity all have 80 tracks. Because very few modern PCs have 40-track
floppy drives, we recommend that you set this field to Disabled to save time.

Boot Up NumLock Status

Toggle between On or Off to control the state of the NumLock key when the system
boots. When toggled On, the numeric keypad generates numbers instead of controlling
cursor operations.

Booy Up System Speed

This item allows you to set the boot speed of your system.

Typematic Rate Setting

When Disabled, the following two items (Typematic Rate and Typematic Delay) are

44

irrelevant. Keystrokes repeat at a rate determined by the keyboard controller in your
system. When Enabled, you can select a typematic rate and typematic delay.

Typematic Rate (Chars/Sec)

When the typematic rate setting is enabled, you can select a typematic rate (the rate at
which character repeats when you hold down a key) of 6, 8, 10,12, 15, 20, 24 or 30
characters per second.

Typematic Delay (Msec)

When the typematic rate setting is enabled, you can select a typematic delay (the delay
before key strokes begin to repeat) of 250, 500, 750 or 1000 milliseconds.

Security Option

If you have set a password, select whether the password is required every time the
System boots, or only when you enter Setup.

PCI/VGA Palette Snoop

Some display cards that are not standard VGA such as graphics accelerators or MPEG
cards may not show the correct colors, the setting can correct this problem once you set
it to Enabled, to default setting leave at Disabled.

Assign IRQ For VGA

Set this option to Yes to allocate an IRQ to VGA device on the PCI Bus. The setting
are Enabled or Disabled.

OS select for DRAM > 64MB

Select OS2 only if you are running OS/2 operating system with greater than 64 MB of
RAM on your system.

45

Shadow

Software that resides in a read-only memory (ROM) chip on a device is called
firmware. The Award BIOS permits shadowing of firmware such as the system BIOS,
video BIOS, and similar operating instructions that come with some expansion
peripherals, such as, for example, a SCSI adaptor.

Shadowing copies firmware from ROM into system RAM, where the CPU can read it
through the 16-bit or 32-bit DRAM bus. Firmware not shadowed must be read by the
system through the 8-bit X-bus. Shadowing improves the performance of the system
BIOS and similar ROM firmware for expansion peripherals, but it also reduces the
amount of high memory (640 KB to 1 MB) available for loading device drivers, etc.

Enable shadowing into each section of memory separately. Many system designers
hardwire shadowing of the system BIOS and eliminate a System BIOS Shadow option.

Video BIOS shadows into memory area C0000-C7FFF. The remaining areas shown on
the BIOS Features Setup screen may be occupied by other expansion card firmware. If
an expansion peripheral in your system contains ROM-based firmware, you need to
know the address range the ROM occupies to shadow it into the correct area of RAM.

PNP OS Installed

This item allows you to determine install PnP OS or not.
The choice: Yes, No.

Resources Controlled by

The Award Plug and Play BIOS can automatically configure all the boot and Plug and
Play-compatible devices. If you select Auto, all the interrupt request (IRQ) and DMA
assignment fields disappear, as the BIOS automatically assigns them.

Reset Configuration Data

Normally, you leave this field Disabled. Select Enabled to reset Extended System
Configuration Data (ESCD) when you exit Setup if you have installed a new add-on
and the system reconfiguration has caused such a serious conflict that the operating
system cannot boot.

PCI IDE 2nd Channel

The IDE standard supports two channels (interfaces) with two devices on each channel.
Enabled the second channel if your system has two PCI IDE connectors in use, either
on the system board or on expansion boards. Disable the second channel if a second
IDE connector is not present or not in use.

53

PCI IRQ Activated By

Leave the IRQ trigger set at Level unless the PCI device assigned to the interrupt
specifies Edge-triggered interrupts.

PCI IDE IRQ Map To

This field lets you select PCI IDE IRQ mapping or PC AT (ISA) interrupts. If your
system does not have one or two PCI IDE connectors on the system board, select values
according to the type of IDE interface(s) installed in your system (PCI or ISA).
Standard ISA interrupts for IDE channels are IRQ14 for primary and IRQ15 for
secondary.

Primary/Secondary IDE INT#

Each PCI peripheral connection is capable of activating up to four interrupts: INT# A,
INT# B, INT# C and INT# D. By default, a PCI connection is assigned INT# A.
Assigning INT# B has no meaning unless the peripheral device requires two interrupt
services rather than just one. Because the PCI IDE interface in the chipset has two
channels, it requires two interrupt services. The primary and secondary IDE INT#
fields default to values appropriate for two PCI IDE channels, with the primary PCI
IDE channel having a lower interrupt than the secondary.

On-Chip Primary/Secondary Master/Slave PIO

The four IDE PIO (Programmed Input/Output) fields let you set a PIO mode (0-4) for
each of the four IDE devices that the onboard IDE interface supports. Modes 0 through
4 provide successively increased performance. In Auto mode, the system automatically
determines the best mode for each device. The choice: Auto, Mode 0, Mode 1, Mode 2,
Mode 3, Mode 4.

On-Chip Primary/Secondary Master/Save UDMA

Ultra DMA/33 implementation is possible only if your IDE hard drive supports it and
the operating environment includes a DMA driver (Windows 95 OSR2 or a third-party
IDE bus master driver). If your hard drive and your system software both support Ultra

55

DMA/33, select Auto to enable BIOS support. The Choice: Auto, Mode 0, Mode 1,
Mode 2.

IDE HDD Block

Block mode is also called block transfer, multiple commands, or multiple sector
read/write. If your IDE hard drive supports block mode (most new drives do), select
Enabled for automatic detection of the optimal number of block read/writes per sector
the drive can support. The Choice: Enabled, Disable.

On-Chip USB Controller

Select Enabled if your system contains a Universal Serial Bus (USB) controller.
The choice: Enabled, Disabled.

USB Keyboard Support

Select Enabled if your system contains a Universal Serial Bus (USB) controller and
you have a USB keyboard. The choice: Enabled, Disabled.

Ring / Wake On LAN Control

An input signal on the serial ring Indicator (RI) line (in other words, an incoming call
on the modem) awakens the system from a soft off state.

Onboard FDC Controller

Select Enabled if your system has a floppy disk controller (FDC) installed on the
system board and you wish to use it. If you install and-in FDC or the system has no
floppy drive, select Disabled in this field. The choice: Enabled, Disabled.

Onboard UART Port1 / Port 2

This item allows you to determine access onboard serial port 1/port 2 controller with
which I/O address. The choice: 3F8/IRQ4, 2E8/IRQ3, 3E8/IRQ4, 2F8/IRQ3, Disabled,
Auto.

UART2 Mode

This item allows you to determine which Infra Red (IR) function of onboard I/O chip.
The choice: Normal, AS KIR, IrDA.

Onboard Parallel Port

This item allows you to determine access onboard parallel port controller with which
I/O address. The choice: 378H/IRQ7, 278H/IRQ5, 3BC/IRQ7, Disabled.

Parallel Port Mode
