## 4.7. tdfx_vid

This is a combination of a Linux kernel module and a video output driver, similar to mga_vid. You'll need a 2.4.x kernel with the `agpgart` driver since `tdfx_vid` uses AGP. Pass `--enable-tdfxfb` to configure to build the video output driver and build the kernel module with the following instructions.

Installing the tdfx_vid.o kernel module:

1. Compile `drivers/tdfx_vid.o`:

       make drivers

2. Then run (as `root`)

       make install-drivers

   which should install the module and create the device node for you. Load the driver with

       insmod tdfx_vid.o

3. To make it load/unload automatically when needed, first insert the following line at the end of `/etc/modules.conf`:

       alias char-major-178 tdfx_vid

There is a test application called tdfx_vid_test in the same directory. It should print out some useful information if all is working well.
