DESCRIPTION

     trident is an XFree86 driver for Trident video cards.  The
     driver is accelerated, and provides support for the follow-
     ing framebuffer depths: 1, 4, 8, 15, 16, and 24. Multi-head
     configurations are supported. The XvImage extension is sup-
     ported on TGUI96xx and greater cards.

SUPPORTED HARDWARE

     The trident driver supports PCI, AGP and ISA video cards
     based on the following Trident chips:

     Blade       Blade3D, CyberBlade series i1, i7 (DSTN), i1, i1
                 (DSTN), Ai1, Ai1 (DSTN), CyberBlade/e4, Cyber-
                 BladeXP, CyberBladeAi1/XP, BladeXP

     Image       3DImage975, 3DImage985, Cyber9520, Cyber9525,
                 Cyber9397, Cyber9397DVD

     ProVidia    9682, 9685, Cyber9382, Cyber9385, Cyber9388

     TGUI        9440AGi, 9660, 9680

     ISA/VLBus   8900C, 8900D, 9000, 9200CXr, Cyber9320, 9400CXi,
                 9440AGi These cards have been ported but need

          for you. Default: on.

     Option "CyberStretch" "boolean"
          For Cyber chipsets only, turn on stretching. When the
          resolution is lower than the LCD's screen, this option
          will stretch the graphics mode to fill the entire LCD.
          Default: off.

     Option "ShadowFB" "boolean"
          Enable or disable use of the shadow framebuffer layer.
          Default: off.

          overlay key. Default: undefined.

     Option "TVChipset" "string"
