NAME
     cgtwelve - accelerated 24-bit color frame buffer

SYNOPSIS
     cgtwelve* at sbus?
     wsdisplay* at cgtwelve?

DESCRIPTION
     The cgtwelve is a triple-slot SBus color frame buffer, with graphics ac-
     celeration and overlay capabilities.

     The cgtwelve driver interfaces the frame buffer with the wscons(4) con-
     sole framework.  It does not provide direct device driver entry points
     but makes its functions available via the internal wsdisplay(4) inter-
     face.

CAVEATS
     The only way to connect a cgtwelve frame buffer to an UltraSPARC is with
     the help of an xbox(4) SBus Expansion subsystem.

     This driver does not support any acceleration features.
