# NAME

`vidcvideo` —
VIDC video device driver

# SYNOPSIS

`vidcvideo0 at vidc0`
`wsdisplay* at vidcvideo0 console ?`

`makeoptions MONITOR="AKF85"`
`makeoptions MODES="1024,768,60 800,600,60"`

# DESCRIPTION

The `vidcvideo` driver provides support for the video system of the ARM VIDC20 and of the video and sound macrocell of the ARM7500 and ARM7500FE within the wscons(4) framework. It provides support for both a text-based console display and a memory-mapped frame buffer usable by the X Window System.

The `vidcvideo` driver chooses a screen mode to use when NetBSD starts up, and has no means of changing it thereafter. The driver attempts to choose a screen mode from its built-in list that most closely matches the mode being used under RISC OS. If the built-in list of modes is inadequate, a different one can be substituted by compiling a kernel using the `MONITOR` option to refer to a RISC OS ModeInfo file, specifying the list of modes to extract from it in `MODES`.

# HISTORY

Before NetBSD 4.0, use of `MONITOR` and `MODES` was compulsory, as there was no built-in list of screen modes.
