Description:

XFree86-S3 is the X server for video cards based on S3 chips,
including most #9 cards, many Diamond Stealth cards, Orchid Farenheits,
Mirco Crystal 8S, most STB cards, and some motherboards with built-in
graphics accelerators (such as the IBM ValuePoint line). Note that if you
have an S3 ViRGE based video card, you'll need XFree86-S3V instead of
XFree86-S3.

If you are installing the X Window System and you have a video card based
on an S3 chip, you should install XFree86-S3. You will also need to
install the XFree86 package, one or more XFree86 fonts packages, the
X11R6-contrib package, the Xconfigurator package and the XFree86-libs
package. And, finally, if you are going to develop applications that
run as X clients, you will also need to install XFree86-devel.
