# vigra(4)

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

## 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)](/wscons/4.md) console framework. It does not provide direct device driver entry points but makes its functions available via the internal [wsdisplay(4)](/wsdisplay/4.md) 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:

| | | | |
| --- | --- | --- | --- |
| **Switches** | **Resolution** | **Refresh** | **Description** |
| **1 2 3 4** |  | **Rate** |  |

### VS12-only Switch Settings:

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

| U U U U | 1280x1024 | 67Hz | Sun SPARCstation, composite sync |

### VS11 Switch Settings:

The VS11 supports a similar set of modes as the VS12, but with higher refresh rates.
