Introduction
Introduction
The high performance 3D graphics card uses the Accelerated Graphics
Port (AGP) interface.AGP utilizes a dedicated pipeline to access system
memory for texturing,z-buffering and alpha blending.
Equipped with the Intel740 graphics chip, its HyperPipelined 3D
architecture provides the following features: Precise Pixel Interpolation
(PPI),Parallel Data Processing (PDP) and Direct Memory Execution (DME).
Precise Pixel Interpolation delivers good image quality, Parallel Data
Processing allows consistent high performance and Direct Memory
Execution delivers 528MB/sec bandwidth providing seamless access to
system memory for unlimited texture sizes and rich rendering.The graphics
chips 3D architecture enables maximum memor y bandwidth for sustained
3D performance and exceptional image quality in PCs equipped with
the Pentium

II processor andAGPset.
Use the graphics card with softwares that support 3D and enjoy more
texture and higher screen resolution at higher frame rates. The graphics
card will deliver faster and better graphics to your PC.

Memory
The graphics card may come with 4MB or 8MB of SGRAM (Syn-
chronous Graphics RAM). A 4MB graphics card is installed with four
256Kx32 SGRAMs while an 8MB graphics card is installed with four
512Kx32 SGRAMs. These SGRAMs are installed at locations U7,
U8, U9 and U10 of the graphics card.

Hardware Installation
VMI Interface
The graphics card supports a VMI (Video Module Interface) interface.
This interface is used for connecting a video module, such as a
MPEG module, to a Video Ready GUI device. The VMI interface
consists of the J5 (40-pins) and J6 (26-pins) connectors.
1. Position the VMI module by aligning the connectors on the
module to J5 and J6 of the graphics card.
2. Make sure pin 1 of the connectors on the VMI module is aligned
with pin 1 of J5 and J6 on the graphics card.
3. Press both sides of the VMI module firmly onto the graphics
card. Make sure the VMI module is seated properly.
Installing the Graphics Card
For most computer systems, you will only need a medium size
Phillips screwdriver to remove the cover and a small flat-blade
screwdriver to secure the monitor cable.
Warning:
Electrostatic discharge (ESD) can damage your graphics card,
system board, processor, disk drives, add-in boards, and other
components. Perform the upgrade instruction procedures
described at an ESD workstation only. If such a station is not
available, you can provide some ESD protection by wearing an
antistatic wrist strap and attaching it to a metal part of the
system chassis. If a wrist strap is unavailable, establish and
maintain contact with the system chassis throughout any
procedures requiring ESD protection.
Handling the Graphics Card
It is quite easy to inadvertently damage your graphics card even
before installing it in your system unit. Electrostatic discharge can
damage computer components without causing any signs of physical
damage. You must take extra care in handling the graphics card to
ensure that no static build-up is present.

AGP-7400 Graphics Card Users Manual
Tips in Handling the Graphics Card
1. To prevent electrostatic build-up, leave the graphics card in its
anti-static bag until you are ready to install it.
2. Do all preparation work on a static-free surface with graphics
card components facing up.
3. Hold the graphics card by its edges only. Be careful not to touch
any of the components, contacts or connections, especially gold
contacts, on the board.
Step 1: Switch Off Your Computers Power
Make sure that your computer is switched off and unplugged before
removing the cover. Also turn off any devices (printer, display, mo-
dem, etc.) you may have attached to your computer.
Warning:
Hazardous voltages are present and exposed when operating
the computer with the cover removed. To prevent equipment
damage and personal injury, never apply power to the com-
puter when the cover is off.
Step 2: Remove Your Computers Cover
Refer to your computer system manual for specific instructions on
removing your computers system unit cover. In general, you will need
to remove several screws on the back or side of the system unit and
then slide the cover off.
Step 3: Remove the Slot Cover
Remove the screw and slot cover (that corresponds to the AGP slot)
located at the back of the system unit. Save the slot cover for future
use. You will be using the screw in step 5.
Step 4: Unpack the Graphics Card
Remove the graphics card from the shipping box and its protective
packing. Please do not throw away the packing material or the shipping
box.You may use these again to prevent damage should you need to
ship the graphics card for repairs.

Step 5: Insert the Graphics Card
Carefully slide the graphics card into the AGP slot. When the cards
edge-connector is aligned with the slot on the system board, press
firmly on the top of the card to seat it. Make sure the graphics card
is straight and level compared to the computers system board by
viewing it from the side. Once you are satisfied with its alignment,
replace the slot covers screw on top of the cards bracket and gently
tighten the screw to stabilize the card.
Step 6: Replace the Computers Cover
When you have finished installing the graphics card, put the cover back
on your computer's system unit. Refer to your computer's system
manual for instructions if necessary.
Note:
The graphics card can only be used with an analog video display
using a 15-pin D-shell cable connector (standard VGA monitor
connection). If your monitor supports analog video but does not
have a 15-pin D-shell connector, see your monitor dealer for the
adapter or optional cable.
After you plug the monitor cable into the VGA connector of the
graphics card, gently tighten the cable screws to hold the connector in
place.
Note:
Some monitors have a switch that chooses between analog and
TTL (or digital) operation. If your monitor has such a switch, set
it for analog.
