# bwtwo(4)

monochromatic frame buffer

## NAME

**bwtwo** – monochromatic frame buffer

## SYNOPSIS

**bwtwo\* at sbus?** **wsdisplay\* at bwtwo?**

## DESCRIPTION

The **bwtwo** is an SBus monochrome frame buffer.

The **bwtwo** driver interfaces the frame buffer with the [wscons(4)](/wscons/4.md) console framework. It does not provide direct device driver entry points but makes its functions available via the internal [wsdisplay(4)](/wsdisplay/4.md) interface.
