rfx - Vitec/Connectware/AP&D RasterFlex framebuffer series
rfx* at sbus? slot ? offset ? wsdisplay* at rfx?
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.
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 described 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).

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 SPARCs- tation 1, 1+ and 2 machines (and their clones) due to hardware limita- tions. MirOS BSD #10-current February 29, 2004 1
