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

NAME
     rfx - Vitec/Connectware/AP&D RasterFlex framebuffer series

SYNOPSIS
     rfx* at sbus?
     wsdisplay* at rfx?

DESCRIPTION
     The RasterFlex series, originally manufactured by Vitec, later bought by
     Connectware, then by Advanced Products & Design, are high-performance
     frame buffers and frame grabber devices.

     The rfx driver only supports the RasterFlex frame buffers:
           RasterFlex-24
           RasterFlex-32
           RasterFlex-HR

     The rfx 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.

DISPLAY RESOLUTION
     The RasterFlex frame buffers will adapt their resolution to the monitor
     they are connected to.  However, when not connected to a Sun monitor, the
     device will default to the 1152x900 resolution, with a refresh rate of
     66Hz.  A different resolution can be forced using the jumpers J2 to J4,
     located near the video connector on the board itself.

     In the following tables, left (L) and right (R) jumper positions are de-
     scribed looking at the board with the video connector on top.  If the
     jumper position is not specified (_), it means it has to be removed
     (open).

CAVEATS
     This driver does not support any acceleration features at the moment, and
     drives the card in PROM-compatible, 8 bit, mode only.

     The rfx cards will not function in the third SBus slot of the Sun SPARC-
     station 1, 1+ and 2 machines (and their clones) due to hardware limita-
     tions.
