# 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 acceleration and overlay capabilities.

The `cgtwelve` driver interfaces the frame buffer with the wscons(4) console framework. It does not provide direct device driver entry points but makes its functions available via the internal wsdisplay(4) interface.

# SEE ALSO

# 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.
