 I2C mainboard interfaces
 CONFIG_I2C_MAINBOARD
- 
+  Many modern mainboards have some kind of I2C interface integrated. This
+  is often in the form of a SMBus, or System Management Bus, which is
+  basically the same as I2C but which uses only a subset of the I2C
+  protocol.
+
+  You will also want the latest user-space utilties: you can find them
+  in the lm_sensors package, which you can download at 
+  http://www.lm-sensors.nu
