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.
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:RemoveYour 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 theAGP 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.

9
AGP-7410 Graphics Card Users Manual
After you plug the monitor cable into theVGA 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 andTTL
(or digital) operation. If your monitor has such a switch, set it for
analog.

Glossary of 3D Features
Alpha Blending - using the alpha component to proportionally weight
the intensity of an object in the summation of all objects within a pixel.
When done correctly, alpha blending can simulate transparency.
Antialiasing - an algorithm to remove the distracting effects of point
sampling a signal in the digital domain. This is necessary because some
of the frequencies present in the signal may be higher than half the
sampling rate. These frequency components "alias" as lower frequency
signals, and show up as "jaggies".
Bilinear Interpolation - an interpolation between four values when
fractional deltas are known in the vertical and horizontal direction.
The horizontal delta is used as the weighting factor to average the
top left and top right values to determine the top, and the bottom
left and bottom right to determine the bottom. The vertical delta is
then used as the weighting factor between the top and bottom value
to calculate the final result.
Direct Memory Execution (DME) - DME is a technique that allows
the graphics accelerator to store and execute textures in system
memory instead of local graphics memory. This provides high levels of
performance and unlimited texture sizes.
Double Buffering - refers to maintaining two separate frame bufffers
(which may physically occupy the same RAM devices). This implies
performing display refreshes from one buffer, while the rendering is
accessing the other one.
Mip Mapping - Mip comes from the Latin, multum in parvo, meaning
many things in a small place. Mip maps contain the original bitmap,
and all successively lower levels of detail. These are usually created by
filtering the original map, decreasing its size by powers of two in both
directions.
Parallel Data Processing (PDP) - PDP contributes to the
HyperPipelined 3D architecture. This is a method of parallelizing 3D
operations allowing several commands to be executed at the same
time in the graphics pipeline. This translates into consistent high-perfor-
mance regardless of the number of features enabled in a scene.

AGP-7410 Graphics Card Users Manual
Perspective Correction - correctly adjusting the interpolation of poly-
gon attributes (primarily texture addresses) so that they appear to
obey the rules of perspective. Perspectively correct interpolation is not
linear in screen space, and requires a divide by depth in order to look
right.
Precise Pixel Interpolation (PPI) - PPI contributes to the
HyperPipelined 3D quality with Intels unique texture engine that deliv-
ers precise accuracy in interpolation operations of pixel values and
color values. This detailed pixel processing maintains a high level of
image quality in every scene.
Shading, Flat - darkening or lightening the intensity of a polygon
based on the angle between its normal and a vector pointing to a
light source. All pixels on a polygon receive the same adjustment,
resulting in a faceted appearance. The per polygon and per pixel cal-
culation load is very light.
Shading, Gouraud - darkening or lighting each pixel of a polygon
based on an interpolation between values calculated at the polygon's
vertices. A "vertex normal" is prescribed or inferred, and the intensity
at that vertex is determined by the angle between that normal and a
vector pointing to a light source. Each pixel is interpolated separately,
producing a simulation of a curved surface. Gouraud shading makes
objects appear to have a matte finish, with no specular components.
The per polygon and per pixel calculation load is moderate.
Z Buffer - a buffer memory that holds the Z (depth) information per
pixel. The Z axis is perpendicular to the X and Y axis of the screen,
and in most practical cases inverse range is uded due to the fact that
it is linear in screen space (where range is not). Compares in depth
between pixels of two polygons can be used to determine occulting
relationships, and only draw the nearer polygon for each pixel.
