+.Nd Voodoo Graphics and VoodooII Memory Access GLIDE Device Driver
+.Sh SYNOPSIS
+.Cd device tdfx
+.Pp
+.Cd options TDFX_LINUX
+.Pp
+.Sh DESCRIPTION
+This driver creates a entry in /dev that allows programs (mostly
+.Em GLIDE-based software )
+to access the device memory of the Voodoo Graphics and
+VoodooII 3D accellerators created by
+.Em 3Dfx, Inc.
+This provides an interface
+for applications based on the
+.Em GLIDE API
+or that simply use the API
+provided by the linux /dev/3dfx device to use the video device.
+.Pp
+Supports all cards based on the following chipsets:
+.Bd -unfilled -offset indent
+.Em 3Dfx Voodoo Graphics
+.Em 3Dfx Voodoo II
+.Ed
+.Pp
+Specifically, the following cards should work:
+.Bd -unfilled -offset indent
+.Em Diamond Multimedia Monster 3D
+.Em Diamond Multimedia Monster 3D II
+.Ed
+.Pp
+Note that this driver does not currently have support for the Voodoo
+Banshee, Voodoo3, Voodoo5, or Voodoo6 based cards. It also does not
+currently support the Voodoo Rush. It also does not yet handle the SLI
+feature of the Voodoo II boards. You can only use each of them
+separately.
+.Pp
+The following kernel configuration options are available:
+.Pp
+.Em options LINUX_TDFX
+.Pp
+Enable the linux ioctl code for this driver, where the only supported
+applications currently reside.
