The S3 Savage chips have the ability to send their output to a variety
of different devices. The Savage3D can display to a standard CRT or
to a TV. The Savage4 and Savage2000 can display to a standard CRT or
through a digital interface to an LCD panel. The Savage/MX and Sav-
age/IX can ship to any two of those three.
The s3switch utility is used to select the devices to be used, and the
format of the TV signal. When invoked with no parameters, s3switch
displays the devices currently attached, and which of those devices
are currently active. Supplying one or more of the words crt, lcd, or
tv makes those devices the active devices. The word both is a
shortcut for the combination of crt and lcd.
