PNOZZ(4)              OpenBSD Programmer's Manual (SPARC)             PNOZZ(4)

NAME
     pnozz - Tadpole Weitek p9100 frame buffer

SYNOPSIS
     pnozz0 at sbus0 slot ? offset ?

DESCRIPTION
     The pnozz is a memory based color frame buffer found on Tadpole SPARCbook
     3GS and 3GX laptops.  It is based on the Weitek Power 9100 and an IBM
     RGB528 RAMDAC.

     The pnozz is configured to emulate a cgthree(4) with a resolution of
     800x600 with 256 colors.  It supports the minimal ioctl's needed to run
     X(1).

     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.

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.
