While installing Intel® Serial IO host controller driver, if you get error message “The setup program ended prematurely because of the following error: This platform is not supported”, don’t worry. The error can be easy to fix. The error would occur if I2C is not enabled in BIOS. To resolve the problem, just enable I2C in BIOS.




   Please refer to the guide below how to enable I2C in BIOS.


   1. Press F2 during boot to enter BIOS Setup.

   2. Go to the Advanced > Devices > Onboard Devices menu.

On the Legacy Device Configuration pane:

   3. Set Pins 13/14 to I2C0_SCL/I2C0_SDA.

   4. Set Pins 15/16 to I2C1_SCL/I2C1_SDA.

   5. Press F10 to save and exit BIOS Setup.


After enabling I2C in BIOS, you can install the Intel® Serial IO host controller driver again.

I2C is enabled for the Low Speed Custom Solutions Header. So if you don’t wish to use the Low Speed Custom Solutions Header, you don’t need to install this driver.
