DESCRIPTION    [Toc]    [Back]

     The tvtwo is a memory based color frame buffer, with  graphics acceleration
 and overlay capabilities, and hardware MPEG decoding.

     The  tvtwo  driver  interfaces  the  frame buffer to the wscons(4) console
     framework.  It does not provide direct device  driver  entry
points but
     makes  its functions available via the internal wsdisplay(4)
interface.

CAVEATS    [Toc]    [Back]

     This  driver  does  not support any acceleration features at
the moment.
     Thus, vertical scrolling in console mode is  abysmally  slow
in 24 bit
     mode.
