-1.  XFree driver for NVidia NV1 / SGS-Thomson STG2000 v1.0
-
-This driver now accelerates bitblits and filled rectangles. It also support a
-hardware cursor.  More graphic acceleration is planned. There is no plan to
-support the audio functionality of the chip.
-
-1.1  Notes
-
-   o THE DRIVER DOES NOT SUPPORT THE VIRTUAL DESKTOP FEATURES OF XFREE86 This
-     is because the NV1 does not have the necessary hardware to support this
-     feature. If you want to change resolutions, you will have to modify your
-     config file. Comment out all but the mode you wish to use.
-
-   o The generic VGA16 server will not work with the NV1.  For this reason
-     XF86Setup cannot be used to configure the server.  Use xf86config
-     instead.  Select `Diamond Edge 3D' as your board, and select only ONE
-     mode for each of 8bpp and 16bpp.  Do not select a virtual desktop.
-     Also, make sure you don't select a RAMDAC or clock chip.
-
-   o The NV1 only supports a 555 RGB Weight in 16 bpp, the hardware does not
-     do 565. You must put a Weight 555 in the Display section.
-
-   o 24/32 bpp mode is not yet supported.
-
-1.2  Known Bugs
-
-   o The driver should force Weight 555 in 16 bpp mode
-
-   o The hardware cursor doesn't work if an doublescan mode is selected.
-
-   o Screen blanking doesn't work, nor does DPMS.
