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 tctrl(4) device is also configured, the pnozz will be powered 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.
