1. Supported chipsets

The Tseng chipsets supported by XFree86 are ET3000, ET4000, ET4000/W32 and ET6000. Accelerated features of the ET4000/W32p and ET6000 are supported by the SVGA driver. For details about the separate accelerated 8bpp (=256 color) ET4000/W32 and ET6000 server, refer to README.W32.

Things that are known NOT to work with the SVGA server in this version (XFree86 3.3) are some ET4000W32 ISA cards (they hang the machine... Use the W32 server XF86_W32 for these cards!), and acceleration on ET4000W32i cards.

In the rest of this document, "8bpp" is short for "8 bits per pixel", which means a 256-color mode. Similarly, 15bpp refers to 32768 colors, 16bpp to 65536 colors , 24bpp to a "packed" 16 million color mode, and 32bpp to a "sparse" 16 million color mode (at 32bpp, only 24 of the 32 bits are actually used, hence the "sparse").

15bpp is only used here to differentiate it from 16bpp, but they are both normally referred to as 16bpp. 15bpp is actually 16bpp with a 5-5-5 color weight (wasting one bit per pixel), while 16bpp is, well, 16bpp, with 5-6-5 color weight.
