[MinnowBoard] Problem with i2c on windows 8.1

I see. So now you can enable the controllers you've routed and in ACPI mode Windows 8.1 drivers will work with them.

Thanks,
Ivan.

Hi Rosario,

I have a green one and a yellow one.
And for me the yellow one works the best, never had a problem.
Some problems with the green one, but power supply was not sufficient with it.

Regards

We designed our custom board which can use same firmware as MinnowMax and has routed different I2C controllers.
