I love it when this actually works! I remember looking this up when it bit me before and while smbus/i2c is included in the pcie spec it's optional and not really implemented in any industry standard way, so you end up with different vendors trying to do different things at boot using it and things sometimes go sideways. I'm glad it worked for you!Argle, if you're ever in Northern Virginia, hit me up. I owe you a beer! That worked beautifully. Thank you
