.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
is a UPA based color frame buffer, found in some Sun SBus and PCI systems.
|
|
The
|
|
.Nm
|
|
driver supports both the Creator/Creator3D, and the Elite3D frame buffers.
|
|
.Pp
|
|
There are several versions of the
|
|
.Nm
|
|
board.

The
|
|
.Sq Creator
|
|
cards have 5MB of on-board memory, support a maximum graphics resolution
|
|
of 1280x1024, and are single-buffered.
|
|
.Pp
|
|
The
|
|
.Sq Creator3D
|
|
cards have 15MB of on-board memory support a maximum resolution of
|
|
1280x1024 double-buffered, and 1920x1360 single-buffered.
|
|
.Pp
|
|
The
|
|
.Sq Elite3D
|
|
cards have 15MB of on-board memory, support a maximum resolution of
|
|
1280x1024, and are always double-buffered.
|
|
The
|
|
.Sq Elite3D-m3
|
|
cards have one hardware geometry engine, whereas the
|
|
.Sq Elite3D-m6
|
|
cards have two.
|
|
.Pp
|
|
The
|
|
.Sq Series 3
|
|
cards are considerably faster than the
|
|
.Sq Series 1
|
|
and
|
|
.Sq Series 2
|
|
cards.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports reading
|
|
.Dv EDID
|
|
data from connected monitors, and will automatically set a resolution that is
|
|
supported by both the card and the monitor if the
|
|
.Dv EDID
|
|
data can be read.
|
|
This can be overridden for the console frame buffer, by setting the
|
|
.Dv output-device
|
|
openprom variable.
|
|
For example, the following openprom command will set the console resolution
|
|
to 1280x1024 @ 60Hz, which will not be altered by the
|
|
.Nm
|
|
driver.

It is necessary to blank the video output when reading

The

Not all

converters connect
|
|
.Dv 13W3
|
|
pin 2 to
|
|
.Dv VGA
|
|
pin 9.
|
|
This pin supplies +5V DC to power the monitor
|
|
.Dv EEPROM ,
|
|
even when the monitor
|
|
is powered off, and is necessary in order to obtain
|
|
.Dv EDID
|
|
data on some monitors.
