Understandably, most SiS fans have imaged within last few
months on the graphics solution for its next generation,
however, SiS are taking a step forward in the development of
their graphics division that brings up mixed feelings in their
supporter community. Well, as most of us know, SiS have
been around for a while so far they have made a couple of
attempts graphics chipsets as SiS-301/ SiS-305 integrated
AGP/PCI VGA controller with full sideband support. The SiS315 is their latest incarnation and is quite an up market
solution to compared to the older SiS at least.
Now, Jaton presence few new AGP accelerators based on
SiS-315 with 256-bit 2D/3D graphics engine, and a high ratio
motion compensation with very competitive market price. All
new accelerators offer a complete 128-bit memory data path
architecture.
3DForce S-series AGP accelerators embedded with a 256-bit
3D engine, also achieve ultra high 2D performance which
maximum memory bandwidth up to 2.7 GB/s. An optimized
3D pipeline architecture is implemented for eliminating the
overhead resulting from texture read, Z-buffer read/write and
destination read latencies and achieving a sustain
throughput of over 90% of peak throughput even when texture,
Z-buffer and alpha blending function are all enable. Likewise,
built-in MPEG I/II video decoder that high performance motion
compensation logic to provide very smooth VCD, DVD &
HDTV playback. Full Scene Anti-Aliasing (FSAA), Transfer a
Lightning (T&L) and AGP 4x bus interface supports were builtin for texels and rendering side-band functions as well.
For feature-rich multimedia solution, the 3DForce S-64Quad
and 3DForce S-128Quad have implanted bridges and ports
on NTSC/PAL (TVout), and Digital Video Out (DVI) functions.

Hardware Installation
Installation Procedures
!! WARNING !!
Discharge static electricity by
touching the GROUND such as
metal part of your case connected
with good power ground before
you handle the electronic circuit
boards.
The manufacturer assumes no liability for any damage,
caused directly or indirectly, by improper installation of
any components by unauthorized service personnel. If you
do not feel comfortable performing the installation,
consult with a qualified computer technician.
Steps:
1. Turn OFF all powers to your system, including any
peripherals (printer, external drives, modem, etc.).
2. Disconnect the power cord and the monitor cable from the
back of the computer.
3. Unfasten the cover mounting screws on your system and
remove the system cover. Refer to your system user
manual for instructions to determine the location of the
mounting screws.
4. Remove the retaining screw that holds the slot cover in
place. Slide the slot cover out and put the screw aside
(you will need it to secure the adapter).
5. To install the adapter in AGP expansion slot, carefully line
up the gold-fingered edge connector on the adapter directly
above the expansion slot connector on the motherboard.
Then press the adapter into place, completely. Use the
(remaining) screw you removed to secure the adapter
retaining bracket in place.
6. Replace the computer cover. Secure the cover with the
mounting screws you removed in Step 3.
You have now completed the installation of your new graphics
adapter on your system.
Software Installation
There may some other ways to proceed the display driver installation
for all Windows operating systems, but we don’t provide those
procedures and details because we believed the driver installations
in this document are illustrated correctly, and deliberately. The
10
following descriptions are the moderate process with Microsoft
InstallShield program.
ÿMicrosoft Windows
( When you powered the computer and boots-up in the
Windows, the Plug-n-Play detects a new hardware and popsup install wizard. Do Not [Cancel] because you need place a
default display setting from Microsoft Windows for your video
adapter, then restart your Windows.)
3DForce S-series Display Drivers Installation and its
procedures are much easier for users to install with
Windows operating systems. After the desktop loaded
completely, insert the software’s CD into CD ROM drive and
Autorun feature pops-up a “Welcome” screen as below.
®
98/Me
1. Click on “Display Driver” text to start your driver
installation.

2. Click on “Next”.
3. Click on “Next” again.

4. Click on “Next” to continue.
5. Wizard has transmit all files now.

6. Click on “Finish” to restart your windows system.
That was very easy to proceed the driver installation after all,
and you may have few interfaces to configure video settings
and functions when the new video driver that runs
appropriately.
ÿMicrosoft Windows
You have to proceeding the setup of service pack6 or above
versions (Microsoft® Windows NT™4.0) first. The software
CD from manufacturer it contains Microsoft NT 4.0 service
pack 6 and its ready to use, so you can progress on that now,
then following steps below to perform the display driver
installation.
