PowerStorm	Actual

3D10		S3 Trio64 (NT only)

Only 3D10, 3D30, 4D10T and 4D20 have XFree86 support.

If you really DO have a 4D20, it is fully supported, regardless of
what the docs (kernel or xfree86) have to say.

Kernels 2.4.x have always had support for it in text mode, as it looks
and behaves just like a VGA, which the frontend Cirrus chipset is.
XFree86 from 4.1.0 on also supports it.

You DO (often) have to put in an appropriate "BusID" option in the
"Device" Section of the XF86Config file, but beyond that, it should
work fine, albeit a bit slow when compared to more modern (and more
fully accelerated) cards. 3D30 will ONLY work in 8-bit mode, and
4D20 ONLY in 24-bit mode.

Kernels 2.6.x should also support either TGA2 fully in text mode
(though the older original TGA is currently problematic, IIRC).

Good luck.
