DESCRIPTION
       nsc  is an Xorg driver for National Semiconductors GEODE processor fam‐
       ily.  It uses the DURANGO kit provided by National Semiconductor.   The
       driver  is  accelerated,	 and provides support for the following frame‐
       buffer depths: 8, 16 and 24.

SUPPORTED HARDWARE
       The nsc driver supports GXLV (5530 companion chip), SC1200, SC1400  and
       GX2 (5535 companion chip).

CONFIGURATION DETAILS
       Please  refer  to xorg.conf(5) for general configuration details.  This
       section only covers configuration details specific to this driver.

       The driver will auto-detect the amount of video memory present for  all
       chips.  If  the	amount	of  memory is detected incorrectly, the actual
       amount of video memory should be specified with a VideoRam entry in the
       config file "Device" section.
