User’s Manual
1.6.2 Intel 855GME and ICH4
The Intel 855GME GMCH components provide the processor interface, DDR SDRAM
interface, display interface, and Hub interface. The Intel 855GME also has an option for
AGP external graphics port, in addition to integrated graphics support for added board
flexibility options.
The Intel 855GM GMCH is in a 732-pin Micro-FCBGA package and contains the following
functionality listed below:
• AGTL+ host bus supporting 32-bit host addressing with Enhanced Intel SpeedStep
technology support
• Supports a single channel of DDR SDRAM memory
• System memory supports DDR200/266 MHz (SSTL_2) DDR SDRAM
• Integrated graphics capabilities: Display Core frequency at 133 MHz or 200 MHz
• Render Core frequency at 100 MHz ,133 MHz, and 200 MHz
• Provides supports four display ports: one progressive scan analog monitor, dual
channel LVDS interface and two DVO port.
The Intel EE GMCH is in a 732-pin Micro-FCBGA package and contains all features listed
above and the additional functionality list below:
• Display Core frequency at 133 MHz, 200 MHz, or 250 MHz
• Render Core frequency at 100 MHz ,133 MHz, 166 MHz, 200 MHz, or 250 MHz
• System memory supports 200/266/333- MHz (SSTL_2) DDR SDRAM.
• Enhanced Power Management Graphics features
The GMCH IGD provides a highly integrated graphics accelerator delivering high
performance 2D, 3D, and video capabilities. With its interfaces to UMA using a DVMT
configuration, an analog display, a LVDS port, and two digital display ports (e.g. flat panel),
the GMCH can provide a complete graphics solution.
The GMCH also provides 2D hardware acceleration for block transfers of data (BLTs). The
BLT engine provides the ability to copy a source block of data to a destination and perform
raster operations (e.g., ROP1, ROP2, and ROP3) on the data using a pattern, and/or
another destination. Performing these common tasks in hardware reduces CPU load, and
thus improves performance. High bandwidth access to data is provided through the system
memory interface. The GMCH uses Tiling architecture to increase system memory
efficiency and thus maximize effective rendering bandwidth. The Intel 855GME GMCH
improves 3D performance and quality with 3D Zone rendering technology. The Intel
855GME GMCH also supports Video Mixer rendering and Bi-Cubic filtering.
AIMB-250 User’s Manual

AIMB-250 Series
The Intel 855GME GMCH has four display ports, one analog and three digital. With these
interfaces, the GMCH can provide support for a progressive scan analog monitor, a
dedicated dual channel LVDS LCD panel, and two DVO devices. Each port can transmit
data according to one or more protocols. The data that is sent out the display port is
selected from one of the two possible sources, Pipe A or Pipe B.
The Intel 855GME GMCH have an integrated dual channel LFP Transmitter interface to
support LVDS LCD panel resolutions up to UXGA The display pipe provides panel
up-scaling to fit a smaller source image onto a specific native panel size, as well as
provides panning and centering support. The LVDS port is only supported on Pipe B. The
LVDS port can only be driven by Pipe B, either independently or simultaneously with the
Analog Display port. Spread Spectrum Clocking is supported: center and down spread
support of 0.5%, 1%, and 2.5% utilizing an external SSC clock.
The DVO B/C interface is compliant with the DVI Specification 1.0. When combined with a
DVI compliant external device (e.g. TMDS Flat Panel Transmitter, TV-out encoder, etc.),
the GMCH provides a high-speed interface to a digital or analog display (e.g. flat panel, TV
monitor, etc.). The DVO ports are connected to an external display device. Examples of this
are TV-out encoders, external DACs, LVDS transmitters, and TMDS transmitters. Each
display port has control signals that may be used to control, configure and/or determine the
capabilities of an external device. The GMCH provides two DVO ports that are each
capable of driving a 165-MHz pixel clock at the DVO B or DVO C interface. When DVO B
and DVO C are combined into a single DVO port, then an effective pixel rate of 330 MHz
can be achieved. The DVO B/C ports can be driven by Pipe A or Pipe
B. If driven on Pipe B, then the LVDS port must be disabled.
The ICH4 is a highly integrated multifunctional I/O Controller Hub that provides the
interface to the PCI Bus and integrates many of functions needed in today’s PC platform.
The GMCH and ICH4 communicate over a dedicated hub interface. The ICH4 functions
and capabilities include:
• PCI Rev. 2.2 compliant with support for 33MHz PCI operations
• Supports up to 6 Request/Grant pairs (PCI slots)
• Power management logic support
• Enhanced DMA controller, interrupt controller, and timer functions
• Integrated IDE controller; Ultra ATA/100/66/33
• USB host interface; 3 host controllers and supports 6 USB ports; includes a EHCI
high-speed 2.0 USB controller

1.6.11 Ethernet
1.6.11.1 Realtek RTL8110S Gigabit Ethernet Controller
The Realtek RTL8110SB(L) LOM Gigabit Ethernet controllers (RTL8110SB (128 QFP) &
RTL8110SBL (128 LQFP)) combine a triple-speed IEEE 802.3 compliant Media Access
Controller (MAC) with a triple-speed Ethernet transceiver, 32-bit PCI bus controller, and
embedded memory. With state-of-the-art DSP technology and mixed-mode signal
technology, they offer high-speed transmission over CAT 5 UTP cable or CAT 3 UTP
(10Mbps only) cable. Functions such as Crossover Detection & Auto-Correction, polarity
correction, adaptive equalization, cross-talk cancellation, echo cancellation, timing recovery,
and error correction are implemented to provide robust transmission and reception
capability at high speeds.
The devices support the PCI v2.3 bus interface for host communications with power
management and are compliant with the IEEE 802.3 specification for 10/100Mbps Ethernet
and the IEEE 802.3ab specification for 1000Mbps Ethernet. They also support an auxiliary
power auto-detect function, and will auto-configure related bits of the PCI power
management registers in PCI configuration space.
They support the Advanced Configuration Power management Interface (ACPI)--power
management for modern operating systems that are capable of Operating System-directed
Power Management (OSPM)--to achieve the most efficient power management possible.
PCI Message Signaled Interrupt (MSI) is also supported.
In addition to the ACPI feature, the RTL8110SB(L) support remote wake-up (including AMD
Magic Packet, Re-LinkOk, and Microsoft® Wake-up frame) in both ACPI and APM
(Advanced Power Management) environments. The LWAKE pin provides four different
output signals including active high, active low, positive pulse, and negative pulse. The
versatility of the LWAKE pin provides motherboards with Wake-On-LAN (WOL)
functionality. To support WOL from a deep power down state (e.g. D3cold, i.e. main power
is off and only auxiliary exists), the auxiliary power source must be able to provide the
needed power for the RTL8110SB(L).
The RTL8110SB(L) is fully compliant with Microsoft® NDIS5 (IP, TCP, UDP) Checksum
and Segmentation Task-offload features, and supports IEEE 802 IP Layer 2 priority
encoding and 802.1Q Virtual bridged Local Area Network (VLAN). The above features
contribute to lowering CPU utilization, especially benefiting performance when in operation
on a network server. Also, the devices boost their PCI performance by supporting PCI
Memory Read Line & Memory Read Multiple when transmitting, and Memory Write and
Invalidate when receiving. To better qualify for server use, the RTL8110SB(L) support the
PCI Dual Address Cycle (DAC) command when the assigned buffers reside at a physical
memory address higher than 4 Gigabytes.

2.3 Jumper and Connector List
You can configure your board to match the needs of your application by setting jumpers. A
jumper is the simplest kind of electric switch.
It consists of two metal pins and a small metal clip (often protected by a plastic cover) that
slides over the pins to connect them. To “close” a jumper you connect the pins with the clip.
To “open” a jumper you remove the clip. Sometimes a jumper will have three pins, labeled 1,
2, and 3. In this case, you would connect either two pins.
The jumper settings are schematically depicted in this manual as follows:
A pair of needle-nose pliers may be helpful when working with jumpers.
Connectors on the board are linked to external devices such as hard disk drives, a
keyboard, or floppy drives. In addition, the board has a number of jumpers that allow you to
configure your system to suit your application.
If you have any doubts about the best hardware configuration for your application, contact
your local distributor or sales representative before you make any changes.
The following tables list the function of each of the board's jumpers and connectors.

User’s Manual
3.1 Starting Setup
The AwardBIOS™ is immediately activated when you first power on the computer. The
BIOS reads the system information contained in the CMOS and begins the process of
checking out the system and configuring it. When it finishes, the BIOS will seek an
operating system on one of the disks and then launch and turn control over to the operating
system.
While the BIOS is in control, the Setup program can be activated in one of two ways:
By pressing <Del> immediately after switching the system on, or
By pressing the <Del> key when the following message appears briefly at the bottom of the
screen during the POST (Power On Self Test).
Press DEL to enter SETUP
If the message disappears before you respond and you still wish to enter Setup, restart the
system to try again by turning it OFF then ON or pressing the "RESET" button on the
system case. You may also restart by simultaneously pressing <Ctrl>, <Alt>, and <Delete>
keys. If you do not press the keys at the correct time and the system does not boot, an error
message will be displayed and you will again be asked to.
Press F1 to Continue, DEL to enter SETUP

Press F1 to pop up 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> or the F1
key again.
3.4 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 AwardBIOS™ supports an override to the CMOS settings which
resets your system to its defaults.
The best advice is to only alter settings which you thoroughly understand. To this end, we
strongly recommend that you avoid making any changes to the chipset defaults. These
defaults have been carefully chosen by both Award and your systems manufacturer to
provide the absolute maximum performance and reliability. Even a seemingly small change
to the chipset setup has the potential for causing you to use the override.

3.5.3 Advanced Chipset Features
This section allows you to configure the system based on the specific features of the
installed chipset. This chipset manages bus speeds and access to system memory
resources, such as DRAM and the external cache. It also coordinates communications
between the conventional ISA bus and the PCI bus. It must be stated that these items
should never need to be altered. The default settings have been chosen because they
provide the best operating conditions for your system. The only time you might consider
making any changes would be if you discovered that data was being lost while using your
system.
The first chipset settings deal with CPU access to dynamic random access memory
(DRAM). The default timings have been carefully chosen and should only be altered if data
is being lost. Such a scenario might well occur if your system had mixed speed DRAM
chips installed so that greater delays may be required to preserve the integrity of the data
held in the slower memory chips.
3.5.3.1 DRAM Timing Selectable
This item allows you to select the DRAM timing value by SPD data or Manual by yourself.
The choices: Manual, By SPD.
3.5.3.2 CAS Latency Time
This item controls the time delay (in clock cycles - CLKs) that passes before the SDRAM
starts to carry out a read command after receiving it. This also determines the number of
CLKs for the completion of the first part of a burst transfer. In other words, the lower the
latency, the faster the transaction.
The choices: 2, 2.5.
3.5.3.3 Active to Precharge Delay
This item is the minimum delay time between Active and Precharge
The choices: 5, 6, 7.
70 AIMB-250 Series User’s Manual
User’s Manual
3.5.3.4 DRAM RAS# to CAS# Delay
This option allows you to insert a delay between the RAS (Row Address Strobe) and CAS
(Column Address Strobe) signals. This delay occurs when the SDRAM is written to, read
from or refreshed. Naturally, reducing the delay improves the performance of the SDRAM
while increasing it reduces performance.
The choices: 2, 3.
3.5.3.5 DRAM RAS# Precharge
This option sets the number of cycles required for the RAS to accumulate its charge before
the SDRAM refreshes. Reducing the precharge time to 2 improves SDRAM performance
but if the precharge time of 2 is insufficient for the installed SDRAM, the SDRAM may not
be refreshed properly and it may fail to retain data
So, for better SDRAM performance, set the SDRAM RAS Precharge Time to 2 but
increase it to 3 if you face system stability issues after reducing the precharge time.
The choices: 2, 3.
3.5.3.6 DRAM Data Integrity Mode
Select ECC if your memory module supports it. The memory controller will detect and
correct single-bit soft memory errors. The memory controller will also be able to detect
double-bit errors though it will not be able to correct them. This provides increased data
integrity and system stability.
The choices: Non-ECC, ECC.
3.5.3.7 MGM Core Frequency
This field sets the frequency of the DRAM memory installed.
The choices: Auto Max 266MHz, 400/266/133/200 MHz, 400/200/100/200 MHz,
400/200/100/133 MHz, 400/266/133/267 MHz, 533/266/133/200 MHz,
533/266/133/266 MHz, 400/333/166/250 MHz, Auto Max 400/333 MHz,
Auto Max 533/333 MHz.
3.5.3.8 System BIOS Cacheable
This feature is only valid when the system BIOS is shadowed. It enables or disables the
caching of the system BIOS ROM at F0000h-FFFFFh via the L2 cache. This greatly
speeds up accesses to the system BIOS. However, this does not translate into better
system performance because the OS does not need to access the system BIOS much.
The choices: Disabled, Enabled.
3.5.3.9 Video BIOS Cacheable
This feature is only valid when the video BIOS is shadowed. It enables or disables the
caching of the video BIOS ROM at C0000h-C7FFFh via the L2 cache. This greatly speeds
up accesses to the video BIOS. However, this does not translate into better system
performance because the OS bypasses the BIOS using the graphics driver to access the
video card's hardware directly.
The Choice: Enabled, Disabled.

3.5.3.10 Memory Hole At 15M-16M
Enabling this feature reserves 15MB to 16MB memory address space to ISA expansion
cards that specifically require this setting. This makes the memory from 15MB and up
unavailable to the system. Expansion cards can only access memory up to 16MB.
The choice: Enable, Disable.
3.5.3.11 Delayed Transaction
This feature is used to meet the latency of PCI cycles to and from the ISA bus. The ISA bus
is much, much slower than the PCI bus. Thus, PCI cycles to and from the ISA bus take a
longer time to complete and this slows the PCI bus down.
However, enabling Delayed Transaction enables the chipset's embedded 32-bit posted
write buffer to support delayed transaction cycles. This means that transactions to and from
the ISA bus are buffered and the PCI bus can be freed to perform other transactions while
the ISA transaction is underway.
This option should be enabled for better performance and to meet PCI 2.1 specifications.
Disable it only if your PCI cards cannot work properly or if you are using an ISA card that is
not PCI 2.1 compliant.
The Choice: Enabled, Disabled.
3.5.3.12 Delay Prior to Thermal
When you system temperature higher, you can set the DRAM access time slowdown
between on 4 min – 32 min delay.
The choice: 4 Min, 8 Min, 16 Min, and 32 Min.
3.5.3.13 AGP Aperture Size (MB)
Select the size of Accelerated Graphics Port (AGP) aperture. The aperture is a portion of
the PCI memory address range dedicated for graphics memory address space. Host cycles
that hit the aperture range are forwarded to the AGP without any translation.
The Choice: 4, 8, 16, 32, 64, 128, 256.
3.5.3.14 Init Display First
This item allows you to decide to active whether PCI Slot or Onboard/AGP first.
The choice: PCI Slot, Onboard/AGP.
3.5.3.15 On-Chip VGA
This item is enabled as the onboard VGA is used.
The Choices: Enabled, Disabled.
3.5.3.16 On-Chip Frame Buffer Size

User’s Manual
Overview
During the Power On Self-Test (POST), if the BIOS detects an error requiring you to do
something to fix, it will either sound a beep code or display a message.
If a message is displayed, it will be accompanied by:
PRESS F1 TO CONTINUE, CTRL-ALT-ESC OR DEL TO ENTER SETUP
Post Beep
Currently there are two kinds of beep codes in BIOS. This code indicates that a video error
has occurred and the BIOS cannot initialize the video screen to display any additional
information. This beep code consists of a single long beep followed by two short beeps.
The other code indicates that your DRAM error has occurred. This beep code consists of a
single long beep repeatedly.
Error Messages
One or more of the following messages may be displayed if the BIOS detects an error
during the POST. This list includes messages for both the ISA and the EISA BIOS.
1. CMOS BATTERY HAS FAILED
CMOS battery is no longer functional. It should be replaced.
2. CMOS CHECKSUM ERROR
Checksum of CMOS is incorrect. This can indicate that CMOS has become corrupt. This
error may have been caused by a weak battery. Check the battery and replace if
necessary.
3. DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER
No boot device was found. This could mean that either a boot drive was not detected or the
drive does not contain proper system boot files. Insert a system disk into Drive A: and
press <Enter>. If you assumed the system would boot from the hard drive, make sure the
controller is inserted correctly and all cables are properly attached. Also be sure the disk
is formatted as a boot device. Then reboot the system.
4. DISKETTE DRIVES OR TYPES MISMATCH ERROR - RUN SETUP
Type of diskette drive installed in the system is different from the CMOS definition. Run
Setup to reconfigure the drive type correctly.

5. DISPLAY SWITCH IS SET INCORRECTLY
Display switch on the motherboard can be set to either monochrome or color. This indicates
the switch is set to a different setting than indicated in Setup. Determine which setting is
correct, and then either turn off the system and change the jumper, or enter Setup and
change the VIDEO selection.
6. DISPLAY TYPE HAS CHANGED SINCE LAST BOOT
Since last powering off the system, the display adapter has been changed. You must
configure the system for the new display type.
7. EISA Configuration Checksum Error
PLEASE RUN EISA CONFIGURATION UTILITY
The EISA non-volatile RAM checksum is incorrect or cannot correctly read the EISA slot.
This can indicate either the EISA non-volatile memory has become corrupt or the slot has
been configured incorrectly. Also be sure the card is installed firmly in the slot.
8. EISA Configuration Is Not Complete
PLEASE RUN EISA CONFIGURATION UTILITY
The slot configuration information stored in the EISA non-volatile memory is incomplete.
Note: When either of these errors appears, the system will boot in ISA mode,
which allows you to run the EISA Configuration Utility.
9. ERROR ENCOUNTERED INITIALIZING HARD DRIVE
Hard drive cannot be initialized. Be sure the adapter is installed correctly and all cables are
correctly and firmly attached. Also be sure the correct hard drive type is selected in Setup.
10. ERROR INITIALIZING HARD DISK CONTROLLER
Cannot initialize controller. Make sure the cord is correctly and firmly installed in the bus.
Be sure the correct hard drive type is selected in Setup. Also check to see if any jumper
needs to be set correctly on the hard drive.
11. FLOPPY DISK CNTRLR ERROR OR NO CNTRLR PRESENT
Cannot find or initialize the floppy drive controller. Make sure the controller is installed
correctly and firmly. If there are no floppy drives installed, be sure the Diskette Drive
selection in Setup is set to NONE.

memory.
Note: When either of these errors appears, the system will boot in ISA mode,
which allows you to run the EISA Configuration Utility.
13. KEYBOARD ERROR OR NO KEYBOARD PRESENT
Cannot initialize the keyboard. Make sure the keyboard is attached correctly and no keys
are being pressed during the boot.
If you are purposely configuring the system without a keyboard, set the error halt condition
in Setup to HALT ON ALL, BUT KEYBOARD. This will cause the BIOS to ignore the
missing keyboard and continue the boot.
14. Memory Address Error at ...
Indicates a memory address error at a specific location. You can use this location along
with the memory map for your system to find and replace the bad memory chips.
15. Memory parity Error at ...
Indicates a memory parity error at a specific location. You can use this location along with
the memory map for your system to find and replace the bad memory chips.
