AP440FX Motherboard Technical Product Specification

1.9.2S3 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.

1.9.3LBP 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.

1.9.4Graphics 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.
