1.9.2 S3 ViRGE/DX Graphics Subsystem
The optional onboard graphics subsystem uses the S3 ViRGE/DX graphics controller, with the
following features:
64-bit graphics engine with accelerator core
24-bit RAMDAC/clock synthesizer
Dual programmable clock generators
DCI-based linear addressing scheme
S3 Streams Processor, which enables the conversion of video data from YUV format to RGB
format and accelerates display scaling while maintaining picture quality and frame rate
3-D graphics support including flat shading, Gouraud shading, and advanced texture mapping
S3 Scenic Highway support for hardware MPEG

The S3 ViRGE/DX graphics controller supports more modes than shown above. The graphics drivers provide options for
additional resolutions.
1.9.3 LBP VESA Feature Connector
The AP440FX motherboard supports a 34-pin VESA feature connector (which also accepts a
26-pin peripheral plug) for synchronizing graphics output with an external NTSC or PAL signal
and a shared frame buffer interface to maximize multimedia performance, as well as the LPB or
Scenic Highway that provides a glueless bi-directional interface to a video companion device such
as an MPEG/live video decoder. The AP440FX also supports other VESA standards such as the
VESA DPMS protocol to put a DPMS compliant monitor into power saving modes and the VESA
Display Data Channel (DDC2B) that permits transfer of monitor identification and resolution
support data for ease of use.
1.9.4 Graphics Drivers and Utilities
Graphics drivers and utilities may be downloaded from the Intel Applications Support web site at
http://www-cs.intel.com/oem_developer/motherbd. Once the site is accessed, perform a keyword
search for the specific application and its driver. Drivers for SCO
UNIX
are available from SCO.
