+.Sh NAME
+.Nm tdvfb
+.Nd 3Dfx Voodoo 2 framebuffer driver
+.Sh SYNOPSIS
+.Cd "tdvfb* at pci?"
+.Cd "wsdisplay* at tdvfb?"
+.Cd "options TDVFB_CONSOLE"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the 3Dfx Voodoo 2 graphics card and provides an
+interface for machine independent
+.Xr wscons 4
+driver.
+.Pp
+Since Voodoo2 was originally designed as a 3D-only solution, most boards do not
+have any kind of firmware.
+The
+.Nm
+driver is albe to do low level initialization (boot) of the board, which means
+that it can be used on all architectures and is truly machine independent.
+However, it also means that driver is can not detect automatically if Voodoo2
+is used as a console.
+.Dv TDVFB_CONSOLE
+option is provided and should be set if the
+.Nm
+driver is intended to be used as a console.

+.Sh AUTHORS
+.An -nosplit
+The
+.Nm
+driver was written by
+.An Radoslaw Kujawa .
+3Dfx Glide 2.x source code, Linux driver by
+.An Ghozlane Toumi
+were used as reference.
+The
+.Xr wscons 4
+attachment code is based mostly on a
+.Xr genfb 4
+driver by
+.An Michael Lorenz .
+.Sh BUGS
+The
+.Nm
+driver is unaccelerated. 3Dfx Voodoo2 has a simple 2D graphics engine but it is
+unsupported yet.
+.Pp
+Video mode is hard coded to 800x600 at 60Hz in 32-bits, it should be selectable
+at least via kernel configuration file.
+It is not possibe to detect what resolutions are supported by the monitor,
+since Voodoo2 has no DDC interface.
+.Pp
+8-bit depth is not supported by the hardware.
+16-bit depth is supported by the hardware and is a prefered depth, however it
+does not work corretly at the moment (this is a driver problem).
