- 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 XF86Config
- file are:
-
- Section "Device"
- Identifier "Intel i740"
- Driver "i740"
- EndSection
-
- or let xf86config 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.
