18 WARNING: If you have an '810' or '815' motherboard, your standard I2C
19 temperature sensors are most likely on the 801's I2C bus. You want the
20 i2c-i801 driver for those, not this driver.
22 Now for the i2c-i810...
24 The GMCH chip contains two I2C interfaces.
26 The first interface is used for DDC (Data Display Channel) which is a
27 serial channel through the VGA monitor connector to a DDC-compliant
28 monitor. This interface is defined by the Video Electronics Standards
29 Association (VESA). The standards are available for purchase at
32 The second interface is a general-purpose I2C bus. It may be connected to a
33 TV-out chip such as the BT869 or possibly to a digital flat-panel display.
38 Both busses use the i2c-algo-bit driver for 'bit banging'
39 and support for specific transactions is provided by i2c-algo-bit.
44 If you enable bus testing in i2c-algo-bit (insmod i2c-algo-bit bit_test=1),
45 the test may fail; if so, the i2c-i810 driver won't be inserted. However,
46 we think this has been fixed.
