To date, the S3-8514-XGA driver has been ported to work on the various Western Digital** accelerators, The Tseng Labs W32 and W32p**, The ATI** Mach 64, and the ATI Mach 32. Of these, only the ATI Mach 32** is similar to an 8514/A**. The amount of code in the driver that is hardware-dependent is relatively small. Still, this is a large set of source modules, and so it is helpful to know where to begin when changing them.

The first part of this section examines the various strategies that can be adopted for porting this driver, and some of the tradeoffs that they entail. The second part of this section consists of an outline for bringing up the driver on a new graphics chip set.
