Introduction

	This is a frame buffer device driver for 3Dfx Banshee and
	Voodoo3 chipsets. It is experimental code; use at your own
	responsibility.

Installation

	The driver is included in the kernel distribution since
	2.3.20; to upgrade, simply copy tdfxfb.c to your kernel source
	tree under drivers/video/, reconfigure and recomple.

	On kernel series 2.2, you need to copy the driver file as
	above, and apply the given patches. cd to drivers/video, and
	do the following:

	# patch < /path/to/patch/files/Config.in.patch.2.2.12
	# patch < /path/to/patch/files/Makefile.patch.2.2.12
	# patch < /path/to/patch/files/fbmem.c.patch.2.2.12

Usage

	You can specify the video mode by passing an argument like

		"video=tdfx:1024x768-8@60" 

	to the kernel, so if you're using, e.g., LILO, add

		append="video=tdfx:1024x768-8@60" 

	to the corresponding kernel image parameters. In kernel 2.3,
	the mode database is used, and you may omit e.g the bit depth
	or the refresh rate, and the mode database will pick the first
	mode that suits the given constraints. In kernel 2.2, the driver
	contains a small list of predefined modes, which you need to
	specify verbatim.
