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

NAME
     vigra - 8-bit SBus color frame buffer with VGA-compatible modes

SYNOPSIS
     vigra* at sbus?
     wsdisplay* at vigra?

DESCRIPTION
     The Vigra VS10, VS11 and VS12 are 8-bit color frame buffers with user-se-
     lectable video modes, and a VGA-compatible connector.

     The vigra 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.

     The video resolution and signal synchronization modes are selected with
     four DIP switches on the back of the card.

   VS10 and VS12 Switch Settings:
     The VS10 and VS12 support the following basic modes:
