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-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.

VS10 and VS12 Switch Settings: #

The VS10 and VS12 support the following basic modes:
