DESCRIPTION    [Toc]    [Back]

     The pninek is a color frame buffer with  graphics  acceleration, embedded
     in the Tadpole SPARCbook 3 laptop.  It is based on the Weitek Power9000
     video processor and a Brooktree Bt445 `Chameleon' RAMDAC.

     Due to specifics of the video hardware on the Tadpole SPARCbook 3, the
     complete driver is split in two parts:

     btcham  RAMDAC interface
     pninek  Video controller interface

     The combination of both btcham and pninek drivers interfaces
the frame
     buffer with the wscons(4) console framework.   They  do  not
provide direct
     device driver entry points but make their function available
via the internal
 wsdisplay(4) interface.

     If the tctrl(4) device is also configured, the  pninek  will
be powered
     down  when  the lid of the laptop is closed or the screen is
blanked.

BUGS    [Toc]    [Back]

     There  is currently no way to switch back and forth from the
onboard display
 to the external  connector.   It  is  not  possible  to
change resolutions.
