+
+<sect>Configuration
+<p>
+The driver auto-detects all device information necessary to
+initialize the card. The only lines you need in the "Device"
+section of your XF86Config file are:
+<verb>
+ Section "Device"
+ Identifier "Intel i740"
+ Driver "i740"
+ EndSection
+</verb>
+or let <tt>xf86config</tt> do this for you.
+
+However, if you have problems with auto-detection, you can specify:
+<itemize>
+ <item>VideoRam - in kilobytes
+ <item>DacSpeed - in MHz
+ <item>MemBase - physical address of the linear framebuffer
+ <item>IOBase - physical address of the memory mapped IO registers
+</itemize>
+
+
+<sect>Driver Options
+<p>
+<itemize>
+ <item>"NoAccel" - Turn off hardware acceleration
+ <item>"SWCursor" - Request a software cursor (hardware is default)
+ <item>"SDRAM" - Force the use of SDRAM timings
+ <item>"SGRAM" - Force the use of SGRAM timings
+ <item>"SlowRam" - Force the use of slower ram timings
+ <item>"Dac6Bit" - Force the use of a 6 Bit Dac (8 Bit is the default)
+ <item>"UsePIO - Force the use of programmed IO (Memory mapped is the default)
+</itemize>
+
+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.
+
+
+<sect>Known Limitations
+<p>
+<itemize>
+ <item>Certain drawing operations are very slow when using 24 bit
+ pixel depth mode.

+ *
+ * REVISION HISTORY:
+ * December 2001 - Patrick LERDA's original (http://sourceforge.net/projects/i740fb).
+ * 27 August 2002 - Patrick's version would run for an hour or two on my machine,
+ * then the screen would go blank (no signal to monitor) and for some reason I
+ * sometimes couldn't even log in through the network. I had to re-boot my machine.
+ * This version fixes that and makes a few other unnecessary tweaks. I am not
+ * certain, but I think the problem is that Patrick's code was reading a value from
+ * XRX register 0xD0, and or'ing with 0x10. When I removed this from the main
+ * loop, it became reliable. I suspect the hardware (whether just my cheap
+ * clone board only I'm not sure) was sometimes returning bogus values, which were
+ * then programmed back in - but I never checked this. This register is related to
+ * powering on or off certain subsystems of the i740 chip, so that might explain
+ * the blank screen. - Stephen Blackheath
+ * 3 September 2002 - Added software scaling in the situation where the screen size is
+ * smaller than the original video size, since scaling down is not supported by
+ * the hardware. The implementation of this is not quite complete.
+ * 12 September 2002 - Better software scaling with some averaging, giving a nicer
+ * picture.
+ * 13 January 2003 - Fixed a minor bug where the video would occasionally stop updating,
+ * which was worked around just by re-sizing the window.
