DESCRIPTION

‘Light’ series of graphics controllers, also known as
‘Entry’ or ‘Starter’ graphics, and designated as
LG1 or LG2, which may be found in Indigo and Crimson systems.
These controllers have a fixed 1024x768 resolution with 8-bit colour depth. Unlike most SGI offerings, both 13W3 and VGA video cables are supported.

NetBSD 5.0 and was ported to
OpenBSD 5.2.

CAVEATS
Much is unknown about the REX chipset. Therefore, the driver relies on the PROM to properly initialise the graphics, and does not support color.
