I've just got this from GigaByte
Dear customer,

Unfortunately there are no linux drivers available, Linux is an "open
source" software; therefore, most of drivers are written/provided by
3rd party. We are continuing to have latest Linux compatibility test
done for every new model; however, features/functions/drivers are not
supported at this moment.
Please search the internet or visit chipset vendor for any drivers
download. Thanks for your understanding and we will soon improve our
Linux support.

Thank you
