At the bottom of the Gigabyte Z77X-UD3H Intel Z77 (Socket 1155) DDR3 Motherboard motherboard page here it says:

Due to different Linux support condition provided by chipset vendors, please download Linux driver from chipset vendors' website or 3rd party website.
What does this mean for a Ubuntu user?

This motherboard will first be set up with a new bios and updates for MS Vista. Once that has been done, a version of Ubuntu will be installed.

Will the motherboard's BIOS need to be flashed again? Will it need to be reconfigured for Ubuntu? I wonder whether the mobo can save a GNU/Linux and Vista profile and use the appropriate one, depending on which OS boots.

At the Intel website, I am not sure what to do.

Please help! Thank you.
