If your mainboard doesn't have a pin header for I2C, you can use the VGA or
DVI output of your graphics adapter for that purpose. The DDC on that
connector is plain I2C/SMBus.
On the VGA connector, Pin 12 is SDA, Pin 15 is SCL and Pin5 is GND.
On the DVI connector, Pin 7 is SDA, Pin 6 is SCL and Pin 15 is GND. As a
bonus, +5V is on Pin 14 on this connector.
Kind regards
