## 1. Introduction

With the release of XFree86 version 4.3.0, the Chips and Technologies driver has been extensively rewritten and contains many new features. This driver must be considered work in progress, and those users wanting stability are encouraged to use the older XFree86 3.3.x versions. However this version of the Chips and Technologies driver has many new features and bug fixes that might make users prefer to use this version. These features include

- The long standing black/blue screen problem that some people have had should be fixed.
- Hardware/Software cursor switching on the fly, that should fix many of the known hardware cursor problems.
- Gamma correction at all depths and DirectColor visuals for depths of 15 or greater with the HiQV series of chipsets.
- Supports PsuedoColor overlays on 16bpp TrueColor screens for HiQV.
- Supports YUV colour space conversion with the XVideo extension.
- 32bpp pixmaps while using a framebuffer in 24bpp packed pixel mode.
- Heaps more acceleration.
- 1/4bpp support.
- Multihead
- Much more...

This document attempts to discuss the features of this driver, the options useful in configuring it and the known problems. Most of the Chips and Technologies chipsets are supported by this driver to some degree.
