You're going to want to see ACKS/NAKS, clocks and other I2C bus activity. You'll need to solder down scl/sda/gnd wiring to the PCB, I generally attached to the eeprom which tends to have larger pins (details on their respective datasheets). It's not hard to do, but does require a small investment in hardware. One the actual bus behavior is documented and understood, you'll likely get a better technical discussion going on. Send me a detailed picture of the PCB and I can probably help spot the I2C bus for you, if you have a low cost bus analyzer and a soldering iron. -- Steven Toth - Kernel Labs http://www.kernellabs.com
