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

vigra* at sbus?
wsdisplay* at vigra?

The Vigra VS10, VS11 and VS12 are 8-bit color frame buffers with user-selectable 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.

The VS10 and VS12 support the following basic modes:
Switches Resolution Refresh Description
1 2 3 4 Rate
640x480 60Hz Standard VGA, negative separate sync
800x600 56Hz Super VGA, negative separate sync
800x600 56Hz Super VGA, positive separate sync
1024x768 60Hz Super VGA, negative separate sync
1024x768 60Hz Super VGA, composite sync

The VS12 supports all of the previously listed modes, as well as a few high resolution settings.
