|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the video system of the
|
|
.Tn ARM VIDC20
|
|
and of the video and sound macrocell of the
|
|
.Tn ARM7500
|
|
and
|
|
.Tn ARM7500FE
|
|
within the
|
|
.Xr 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.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver chooses a screen mode to use when
|
|
.Nx
|
|
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
|
|
.Tn RISC \&OS .
|
|
If the built-in list of modes is inadequate, a different one can be substituted
|
|
by compiling a kernel using the
|
|
.Cd MONITOR
|
|
option to refer to a
|
|
.Tn RISC \&OS
|
|
ModeInfo file, specifying the list of modes to extract from it in
|
|
.Cd MODES .

.Sh HISTORY
|
|
Before
|
|
.Nx 4.0 ,
|
|
use of
|
|
.Cd MONITOR
|
|
and
|
|
.Cd MODES
|
|
was compulsory, as there was no built-in list of screen modes.
