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