NAME
     smg - Small Monochrome Graphics frame buffer

SYNOPSIS
     smg0 at vsbus0 csr 0x200f0000
     wsdisplay* at smg?

DESCRIPTION
     The smg is a monochrome frame buffer found on-board most VAXstation 3100
     systems.

     The smg 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.

     When a color option board (either a gpx(4) or a spx frame buffer) is
     installed, the smg driver will not attach by default, since the color
     option takes over the video connector on the back of the system.
     However, the output signal pins are independent, and it is possible to
     connect a monochrome video cable even if a color option board is
     installed.	 To force the smg driver to attach in this case, change the
     device flags to 1.	 It will however not be possible to use the monochrome
     frame buffer as the OpenBSD console in this case.
