SYNOPSIS

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
NetBSD4.0,
use of
MONITOR
and
MODES
was compulsory, as there was no built-in list of screen modes.
