+
+  5.  Configuration
+
+  The driver auto-detects all device information necessary to initialize
+  the card.  The only lines you need in the "Device" section of your
+  xorg.conf file are:
+
+         Section "Device"
+             Identifier "Intel i740"
+             Driver     "i740"
+         EndSection
+
+
+  or let xorgconfig do this for you.
+
+  However, if you have problems with auto-detection, you can specify:
+
+  +o  VideoRam - in kilobytes
+
+  +o  DacSpeed - in MHz
+
+  +o  MemBase  - physical address of the linear framebuffer
+
+  +o  IOBase   - physical address of the memory mapped IO registers
+
+
+
+  6.  Driver Options
+
+
+  +o  "NoAccel"  - Turn off hardware acceleration
+
+  +o  "SWCursor" - Request a software cursor (hardware is default)
+
+  +o  "SDRAM"    - Force the use of SDRAM timings
+
+  +o  "SGRAM"    - Force the use of SGRAM timings
+
+  +o  "SlowRam"  - Force the use of slower ram timings
+
+  +o  "Dac6Bit"  - Force the use of a 6 Bit Dac (8 Bit is the default)
+
+  +o  "UsePIO    - Force the use of programmed IO (Memory mapped is the
+     default)
+
+  Note: the i740 X server should automatically detect whether your card
+  has SGRAM or SDRAM.  Use the "sgram" and "sdram" options if it is
+  incorrectly detected.
+
+
+
+  7.  Known Limitations
+
+
+  +o  Certain drawing operations are very slow when using 24 bit pixel
+     depth mode.
