Overview

Advanced Features

This mainboard comes equipped with the most advanced new features that not only
optimize the performance of the latest processors but also enhance the
manageablity, power management capabilities, and user-friendliness of your system.
This section provides detailed information on these features, and how they are
implemented on the mainboard.

n Optimized Celeron PPGA Processor Performance

The mainboard utilizes the advanced features of the Intel 440LX AGPset to
optimize the unrivaled performance of the Celeron PPGA processor with MMX
 technology, allowing you to enjoy a richer video, audio, digital imaging and
communications experience from the latest generation of multimedia software.

n Onboard Accelerated Graphics Port (AGP)

The 32-bit AGP bus provides a dedicated 66MHz/133MHz path from the graphics
card to the system memory offering a much greater bandwidth than the 32-bit PCI
bus does which currently operates at a speed of 33MHz. AGP enabled 3D graphics
cards can directly access main memory across this fast path instead of using local
memory. This is especially important for memory-intensive 3D graphics
applications so as to produce a more detailed 3D texture, greater clarity and higher
levels of resolution without compromising system performance. This mainboard is
fully compliant with the AGP 1.0 specification. To make use of the improved AGP
performance, the mainboard should be installed with SDRAM type memory and
the VGA card and drivers should also be fully AGP compliant. Using Microsoft

Microsoft Windows 98 and forthcoming versions of Windows NT v.5.0

which implement DirectDraw will allow the system to take full use of AGP
benefits without the need to install additional drivers.

Intel LANDesk Client Manager (optional)

The mainboard comes with optional Intel LANDesk Client Manager, a Desktop
Management Interface (DMI) compliant application that simplifies local and
network management of desktop client systems by monitoring PC health, and by
alerting local and designated remote users of potential problems. For example, the
application will indicate when memory usage is high or hardware components are
likely to fail. This capability provides new levels of manageability to deliver a lower
cost of PC ownership by maximizing system uptime, increasing user productivity
and reducing the number of help desk calls. Because it is industry-standard DMI
compliant, Intel LANDesk Client Manager can be used with other DMI-based
network management tools.

Installation Procedures

2). Install RAM Modules

SDRAM

The working space of the computer is the Random Access Memory (RAM). The
system cannot act upon data unless it is loaded into RAM. When more memory is
added, the working memory of the computer is larger, thereby increasing total
performance. The mainboard RAM is comprised of two 168 in Dual In ine

Memory Modules (DIMMs). Each DIMM socket is able to support up to 128MB
lightning-fast SDRAM.

SDRAM features an on hip burst counter that can be utilized to increment
column addresses for very fast burst access, which means that SDRAM allows new

memory access to be initiated before the preceding access has been finished.
Before making DRAM upgrades you should verify the type and speed of the RAM

currently installed from your dealer. Installing mixtures of RAM types other than
those described in this manual will have unpredictable results.

RAM Module Configuration

The mainboard provides two onboard DIMM sockets allowing 3.3V (unbuffered)
SDRAM DIMM modules. Either 8, 16, 32, 64, 128, or 256MB DIMM can be
installed on these two sockets. The maximum total memory supported is up to
256MB.

Setting BIOS Feature

All computer mainboards provide a Setup utility program for specifying the
system configuration and settings. If the mainboard came in a computer
system, the proper configuration entries may have already been made. If you
are installing the mainboard or reconfiguring the system or if you receive a
Run Setup message, you will need to enter new setup information.

The mainboard comes with the Award BIOS chip that contains the ROM
Setup information of the system. This chip serves as an interface between
the processor and the rest of the mainboard's components. This chapter
explains the information contained in the Setup program and tells you how
to modify the settings according to the system configuration.

A Setup program built into the system BIOS, is stored in the CMOS RAM.
This Setup utility program allows changes to the mainboard configuration
settings. It is executed when user changes system configuration; user
changes system backup battery; or the system detects a configuration error
and asks the user to run the Setup program. At power-on RAM testing, the
message Press <Delete> key to enter Setup appears. If you are a little bit
late pressing the mentioned key, POST (Power-On Self Test) will continue
with its test routines, thus preventing you from calling up Setup. If you still
need to call Setup, reset the system by simultaneously pressing the <Ctrl>,
<Alt> and <Delete> keys, or by pushing the Reset button on the system
case. You can also restart by turning the system off and then back on again.
But do so only if the first two methods fail. Use the arrow keys to select and
press <Enter> key to run the selected program.

Advanced Configuration & Power Interface (ACPI)

The BIOS Setup has built-in ACPI interface which enables and supports
reliable power management through improved hardware and operating
system coordination. The Specification enables new power management
technology to evolve independently in operating systems and hardware
while ensuring that they continue to work together. An ACPI compatible
BIOS could:

of running software

Main CMOS Setup

When you run Setup, the CMOS SETUP UTILITY main program screen
will appear with the following options:

A section at the bottom of the above screen displays the control keys for this
screen. Take note of these keys and their respective uses. Another section
just below the control keys section displays information on the currently
highlighted item in the list.

Setting BIOS Feature

Standard CMOS Setup

The tandard CMOS Setup” option allows you to record some basic
system hardware configuration and set the system clock and error handling.
If the mainboard is already installed in a working system, you will not need
to select this option anymore. However, if the configuration stored in the
CMOS memory on the mainboard gets lost or damaged, or if you change
the system hardware configuration, you will need to re-specify the
configuration values. The configuration values usually get lost or corrupted
when the power of the onboard CMOS battery weakens.

The above screen provides you with a list of options. At the bottom are the
control keys for this screen. Take note of these keys and their respective
uses. User-configurable fields appear in a different color. If you need
information on the selected field, press the <F1> key. The help menu will
then appear to provide you with the information you need. The memory
display at the lower right-hand side of the screen is read-only and
automatically adjusts accordingly.

the current settings.

Hard Disks

This field records the specifications for all non-SCSI hard drives installed in the
system. The onboard PCI IDE connectors provide Primary and Secondary channels
for connecting up to four IDE hard disks or other IDE devices. Each channel can
support up to two hard disks, the first of which is the aster” and the second is

the lave”.

Specifications for SCSI hard disks need not be entered here since they
operate using device drives and are not supported by any BIOS. If you
installed a SCSI controller card, please refer to their respective
documentations on how to install the required SCSI drivers.

For an IDE hard disk drive setup, you can:

• Use the Auto setting for detection during bootup.

• Use the IDE HDD AUTO DETECTION in the main menu to automatically enter

the drive specifications.

• Enter the specifications yourself manually by using the ser” option.

The entries for specifying the hard disk type include CYLS (number of
cylinders), HEAD (number of read/write heads), PRECOMP (write
precompensation), LANDZ (landing zone), SECTOR (number of sectors)
and MODE. The SIZE field automatically adjusts according to the
configuration you specified. The documentation that comes with the hard
disk should provide you with the information regarding the drive
specifications.

The MODE entry is for IDE hard disks only, and can be ignored for MFM
and ESDI drives. This entry provides three options: Normal, Large, LBA, or
Auto. Set MODE to the Normal for IDE hard disks smaller than 528MB; set
it to LBA for drives over 528MB that support Logical Block Addressing
(LBA) to allow large IDE hard disks; set it to Large for drives over 528MB
that do not support LBA. Large type of drives can only be used with MS­DOS and is very uncommon. Most IDE drives over 528MB support the LBA
mode.

Setting BIOS Feature

Auto Detection of Hard Disks on Bootup

For each field: Primary Master, Primary Slave, Secondary Master, and Secondary
Slave, you can select Auto under the TYPE and MODE fields. This will enable auto
detection of your IDE drives during Bootup. This will allow you to change your hard
drives (with the power off) and then power on without having to reconfigure your
hard drive type. If you use older hard drives which do not support this feature, then
you must configure the hard drive in the standard method as described above by the

ser” option.

NOTE : After the IDE hard disk information has been entered into

BIOS, new IDE hard disks must be partitioned (such as with

IDE HDD Auto Detection

The DE HDD Auto Detection” option detects the parameters of an IDE
hard drive and automatically enters them into the Standard CMOS Setup
screen. Up to four IDE drives can be detected, with parameters for each
listed inside the box. To accept the optimal entries, press the <Y> key or
else select from the numbers displayed under the OPTIONS field; to skip to
the next drive, press the <N> key. If you accept the values, the parameters
will appear listed beside the drive letter on the screen. The process then
proceeds to the next drive letter. Pressing the <N> key to skip rather than to
accept a set of parameters causes the program to enter zeros after that drive
letter.

Remember that if you are using another IDE controller that does not feature
Enhanced IDE support for four devices, you can only install two IDE hard
drives. The IDE controller must support the Enhanced IDE features in order
to use Drive E and Drive F.

When auto-detection is completed, the program automatically enters all
entries you accepted on the field for that drive in the Standard CMOS Setup
screen. Skipped entries are ignored and are not entered in the screen.

If you are auto-detecting a hard drive that supports the LBA mode, three
lines will appear in the parameter box. Choose the line that lists LBA for an
LBA drive. Do not select Large or Normal.

The auto-detection feature can only detect one set of parameters for a
particular IDE hard drive. Some IDE drives can use more than one set. This
is not a problem if the drive is new and there is nothing on it.

NOTE : If your hard drive was already formatted on an older previous

system, incorrect parameters may be detected. You will need to
enter the correct parameters manually or use low-level format if
you do not need the data stored on the hard drive.

If the parameters listed differ from the ones used when the drive was
formatted, the drive will not be readable. If the auto-detected parameters do
not match the ones that should be used for your drive, do not accept them.
Press the <N> key to reject the presented settings and enter the correct ones
manually from the Standard CMOS Setup screen.
