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.
The pnozz driver interfaces the frame buffer with the wscons(4) console
framework. It does not provide direct device driver entry
makes its functions available via the internal wsdisplay(4)
If the tctrl(4) device is also configured, the pnozz will be
when the lid of the laptop is closed or the screen is
agten(4), bwtwo(4), cgeight(4), cgfour(4), cgfourteen(4),
cgthree(4), cgtwelve(4), cgtwo(4), intro(4), mgx(4),
sbus(4), tctrl(4), tcx(4), tvtwo(4), vigra(4), wscons(4),
There is currently no way to switch back and forth from the
to the external connector. It is not possible to
or color depth.
