System Board

1.1 Features

The DX6G Plus is a dual-processor system board built on an
extended ATX baseboard utilizing two Pentium®II processors running
at 400/100 and 450/100 MHz or two Pentium®III processors running
at 500/100 and 550/100 MHz. It is integrated with the Intel 440GX
system controller, which consists of the PCI/AGP controller and the
PCI/ISA IDE accelerator (PIIX4E).

The Pentium®II and Pentium®III processor implements a Dynamic
Execution micro-architecture - a unique combination of multiple
branch prediction, data flow analysis, and speculative execution. This
means that it can deliver higher performance than the previous
Pentium®processor while maintaining binary compatibility with all
previous Intel Architecture processors.

The PCI/AGP controller host bus interface supports both Pentium®II
and Pentium®III with 100 MHz bus frequency. It also provides a 72­bit DIMM that supports synchronous DRAM (SDRAM) DIMMs. The
PCI/AGP controller introduces a new technology, which is the
Accelerated Graphics Port (AGP) interface. Supporting up to
533MB/sec MHz data transfer rate, the AGP interface boosts graphics
performance.

The PIIX4E is a multifunctional PCI device controller implementing
system functions including PCI IDE, universal serial bus (USB)
host/hub, and enhanced power management. It also supports Ultra
DMA/33 synchronous DMA-compatible devices.

System Board 1-1

The four DIMM sockets on board allow memory upgrade to a
maximum of 2048 MB and supports 72-bit DIMM using synchronous
DRAM (SDRAM) DIMMs.

Two 16-bit Ultra-2 SCSI (Small Computer System Interface) and an
8-bit fast narrow SCSI comes with the system board to connect SCSI
devices.

The system board also supports the USB (Universal Serial Bus)
connector, and other standard features such as two UART NS16C550
serial ports, one enhanced parallel port with Enhanced Parallel Port
(EPP)/Extended Capabilities Port (ECP) feature, a diskette drive
interface, and two embedded hard disk interfaces. The board also
includes a built-in 10/100 Mb/s Intel 82558 LAN chip that supports
Wake-On-LAN (WOL).

The system supports the power-management function that conforms
to the power-saving standards of the U.S. Environmental Protection
Agency (EPA) Energy Star program. It also offers the Plug-and-Play
feature. This feature saves the user from configuration troubles, thus
making the system more user-friendly. The system board support Intel
LDCM© (LAN Desktop Client Manager) which will detect problems in
CPU thermal condition, CPU working voltage, CPU fan and the
chassis fan malfunctions. It also provides remote monitoring features.

The system is fully compatible with MS-DOS V6.X, Novell Netware,
Novel SFT III, SCO UNIX, Windows NT and Windows 95/98 operating
systems

The four 168-pin sockets onboard support SDRAM-type DIMMs. You
may install 16-MB, 32-MB, 64-MB, 128-, 256-, or 512-MB (single and
double density) DIMMs for a maximum of 2048-MB system memory.

The SDRAM DIMMs should work under 3.3 volts only; 5 volt memory
devices are not supported. DX6G Plus supports both 100MHz
standard and registered SDRAM. However, please do not use them at
the same time.

Do not use both 66 MHz (unbuffered) and
100 MHz (registered) SDRAM together. This
might cause your system to malfunction.

Each of the sockets represents one independent bank. This allows
you to install DIMMs with different capacities to form a configuration.

1.10 Error Messages

Do not continue using the computer if you receive an error message
of any type. Note the message and take corrective action. This
section explains the different types of error messages and
corresponding corrective measures.

There are two general types of error messages:

• Software

• System

1.10.1 Software Error Messages

Software error messages are returned by your operating system or
application. These messages typically occur after you boot the
operating system or when you run your applications. If you receive
this type of message, consult your application or operating system
manual for help.

1.10.2 System Error Messages

A system error message indicates a problem with the computer itself.
A message of this type normally appears during the power-on self­test, before the operating system prompt appears.

1.10.3 Correcting Error Conditions

As a general rule, if an error message says "Press F1 to continue," it
is caused by a configuration problem, which can be easily corrected.
An equipment malfunction is more likely to cause a fatal error, i.e., an
error that causes complete system failure.

Here are some corrective measures for error conditions:

1. Run Setup. You must know the correct configuration values for
your system before you enter Setup, which is why you should
write them down when the system is correctly configured. An
incorrect configuration is a major cause of power-on error
messages, especially for a new system.

2. Remove the system unit cover. Check that the jumpers on the
system board and any expansion boards are set correctly.

3. If you cannot access a new disk, it may be because your disk is
not properly formatted. Format the disk first using the FDISK and
FORMAT commands.

4. Check that all connectors and boards are securely plugged in.

If you go through the corrective steps above and still receive an error
message, the cause may be an equipment malfunction.

If you are sure that your configuration values are correct and your
battery is in good condition, the problem may lie in a damaged or
defective chip.

In either case, contact an authorized service center for assistance.

Setup Utility

Most systems are already configured by the manufacturer or the
dealer. There is no need to run Setup when starting the computer
unless you get a Run Setup message.

The Setup program loads configuration values into the battery-backed
nonvolatile memory called CMOS RAM. This memory area is not part
of the system RAM.

If you repeatedly receive Run Setup
messages, the battery may be bad. In this
case, the system cannot retain configuration
values in CMOS. Ask a qualified technician
for assistance.

Before you run Setup, make sure that you have saved all open files.
The system reboots immediately after you exit Setup.

2.4.2 LS-120 Drive As

This parameter allows you not only to enable the LS-120 device
installed in your system, but also to specify the function of the device.
The setting affects how BIOS will detect the device.

Possible settings are:

• Normal In this setting, BIOS does not support the LS-120

drive. The drive needs the LS-120 device driver to operate.

• Drive A BIOS recognizes the LS-120 drive as drive A. If a

standard diskette drive A exists, BIOS automatically identifies it
as drive B. If a standard diskette drive B exists, it automatically
becomes inaccessible.

If two LS-120 drives exist, BIOS recognizes them as drive A and
drive B, respectively.

• Drive B BIOS recognizes the LS-120 drive as drive B. If a

standard diskette drive B exists, it becomes inaccessible.

• Hard Disk BIOS recognizes the LS-120 drive as a hard disk.

In this setting, format the LS-120 drive as any other hard disk and
assign it a drive letter C, D, E, and so on. See the documentation
that came with the LS-120 drive for more information.

Enhanced IDE Features

HARD DISK SIZE > 504 MB

When set to Auto, the BIOS utility automatically detects if the installed
hard disk supports the function. If supported, it allows you to use a
hard disk with a capacity of more than 504 B. This is made possible
through the Logical Block Address (LBA) mode translation. However,
this enhanced IDE feature works only under DOS, Windows 3.x,
Windows 95, and Windows NT 3.5 and above. Other operating
systems require this parameter to be set to Disabled.

HARD DISK BLOCK MODE

This function enhances disk performance depending on the hard disk
in use. If you set this parameter to Auto, the BIOS utility automatically
detects if the installed hard disk drive supports the Block Mode
function. If supported, it allows data transfer in blocks (multiple
sectors) at a rate of 256 bytes per cycle. To disregard the feature,
change the setting to Disabled.

ADVANCED PIO MODE

When set to Auto, the BIOS utility automatically detects if the installed
hard disk supports the function. If supported, it allows for faster data
recovery and read/write timing that reduces hard disk activity time.
This results in better hard disk performance. To disregard the feature,
change the setting to Disabled.

HARD DISK 32-BIT ACCESS

Enabling this parameter improves system performance by allowing
the use of the 32-bit hard disk access. This enhanced IDE feature
works only under DOS, Windows 3.x, Windows 95, Windows NT, and
Novell NetWare. If your software or hard disk does not support this
function, set this parameter to Disabled .

A PCI master can burst indefinitely as long as the target can
source/sink the data, and no other agent requests for the bus. If
another PCI device requests for the use of the PCI bus, a PCI bus
arbitration takes place, and the tenure of the device currently using
the PCI bus cannot go over the PCI latency time set in BIOS. This
setting depends on your application. For example, if you install a high
bandwidth block I/O card, e.g., FDDI, the longer the latency time the
better. This setting only affects the primary PCI components (PCI
slots 1, 2, 3, AGP slot, and onboard LAN). The secondary PCI
components are always set to 20 PCI clocks.

Setting this parameter to Yes allows you to assign the same IRQ to
two different devices. To disable the feature, select No.

If there are no IRQs available to assign for the
remaining device function, we recommend that you
enable this parameter.

VGA PALETTE SNOOP

This parameter permits you to use the palette snooping feature if you
installed more than one VGA card in the system.

The VGA palette snoop function allows the control palette register
(CPR) to manage and update the VGA RAMDAC (Digital Analog
Converter, a color data storage) of each VGA card installed in the
system. The snooping process lets the CPR send a signal to all the
VGA cards so that they can update their individual RAMDACs. The
signal goes through the cards continuously until all RAMDAC data has
been updated. This allows the display of multiple images on the
screen.

Some VGA cards have required settings for
this feature. Check your VGA card manual
before setting this parameter.

GRAPHICS APERTURE SIZE

This parameter determines the effective size of the graphics aperture.
Graphics aperture is the address range that the AGP video and the
CPU use to manage graphical objects. The lowest setting is 8 B
and the highest is 256 B.

PLUG AND PLAY OS

When this parameter is set to Yes, BIOS initializes only PnP boot
devices such as SCSI cards. When set to No, BIOS initializes all PnP
boot and non-boot devices such as sound cards.

Set this parameter to Yes only if your operating
system is Windows 95/98.

RESET RESOURCE ASSIGNMENTS

Set this parameter to Yes to avoid IRQ conflict when installing
non-PnP or PnP ISA cards. This clears all resource assignments and
allows BIOS to reassign resources to all installed PnP devices the
next time the system boots. After clearing the resource data, the
parameter resets to No.

2.10.3 Memory/Cache Options

The Memory/Cache Options allows you to configure the advanced
system memory functions.

Memory/Cache Options

Internal Cache(CPU Cache)........... [Enabled ]

External Cache...................... [Enabled ]

Cache Scheme...................... Write Back

Memory at 15MB-16MB Reserved for ... [System]

Memory Mode......................... [ECC]

Multi-Processor Spec. Version....... [V1.4]

Single Processor MP Table........... [Enabled]

Internal Cache (CPU Cache)

This parameter enables or disables the first-level or internal memory,
that is, the memory integrated into the CPU. The default setting is

Enabled.

External Cache

This parameter enables or disables the external cache memory. The
external cache is incorporated in the CPU module.

Setup Utility 2-45

CACHE SCHEME

This parameter shows the cache scheme status only as Write-back
mode. Write-back updates the cache but not the memory when
there is a write instruction. It updates the memory only when there is
an inconsistency between the cache and the memory.

Memory at 15MB-16MB Reserved for

To prevent memory address conflicts between the system and
expansion boards, reserve this memory range for the use of either the
system or an expansion board.

Memory Mode

This parameter allows you to enable or disable the ECC (Error
Checking and Correction) feature. The ECC feature enables BIOS to
detect and correct data errors. Disable this parameter if you want to
disregard the function.

Multi-Processor Spec. Version

This parameter allows you to choose the version of the Multi­Processor Specifications. The default version is V1.4. You can also
choose version V1.1.

Single Processor MP Table

Enabling this parameter allows BIOS to create a multiprocessor (MP)
table for Multi-Processor OS (ex: Windows NT) use. In a single­processor system running Windows NT, you may disable this
parameter to enhance system performance. If you install another
CPU for a dual system, enable this parameter then re-install Windows
NT.

2-46 User’s Guide

In cases when this parameter is enabled before installing Windows
NT in a single-processor system, you may upgrade to a
multiprocessor system without reinstalling Windows NT.

2.10.4 CPU Frequency

This parameter displays your CPU speed and bus frequency.
Selecting this option displays the following screen:

CPU Frequency

Bus Frequency................ 100 MHz

CPU Multiple................. [4]

Processor Speed.............. xxx MHz

Bus Frequency

The bus frequency refers to the speed by which data is transferred
between internal computer components and the CPU or the main
memory of the CPU. A fast bus allows data to be transferred faster,
which makes applications run faster.

CPU Multiple

This parameter sets the Core/bus ratio of your system. The clock
speed of the bus does not necessarily equal the CPU (core). The
bus clock speed is often slower than the CPU clock speed.

2-48 User’s Guide

Processor Speed

The processor speed is the speed at which a microprocessor
executes instructions. Clock speeds are expressed in megahertz
(MHz), with 1 MHz being equal to 1 million cycles per second. The
faster the clock, the more instructions the CPU can execute per
second.
