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 powered down
when the lid of the laptop is closed or the screen is blanked.
Support for the pnozz
first appeared in
NetBSD 1.6.
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 or color
depth.
