<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 xorg.conf file are:
|
|
<verb>
|
|
Section "Device"
|
|
Identifier "Intel i740"
|
|
Driver "i740"
|
|
EndSection
|
|
</verb>
|
|
|
|
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.
