NAME

     pnozz -- Weitek Power9100 accelerated frame buffer


SYNOPSIS

     pnozz0 at sbus? slot ? offset ?


DESCRIPTION

     The pnozz is a color frame buffer with graphics acceleration, embedded in
     the Tadpole SPARCbook 3GS, 3GX, 3TX, and 3XP laptops.  It is based on the
     Weitek Power9100 video processor and an IBM RGB525 RAMDAC.

     If the sparc/tctrl(4) device is also configured, the pnozz will be pow-
     ered down when the lid of the laptop is closed or the screen is blanked.

HISTORY

     Support for the pnozz first appeared in NetBSD 1.6.


BUGS

     There is currently no way to switch back and forth from the onboard dis-
     play to the external connector.  It is not possible to change resolutions
     or color depth.
