UEFI (BIOS) designs are a delicate mix between allowing the user to make system changes quickly and displaying information the user needs. The Gigabyte UEFI is all business and styled after the classic interface. In fact, aside from the colors the layout and interface is identical.
Below are some of the more interesting screens found in the GA-Z170X-UD5 BIOS.(in no particular order)
As with all BIOS menus it is a good idea to root around and identify all of the settings you are looking for and discover what their dependencies might be.
This may seem like a minor annoyance but with the advent of the UEFI you have been given a chance to take a screenshot of your BIOS screens. Typically your only option to save the image is to a USB drive however the UD5 allows you to save “some” of the screens to your SSD assuming you aren’t trying to screenshot a dialog box. Overall this is a cool feature however, instead of saying “Mfg SSD 1 or USB 1” they are listing the hardware address and expecting you to know which drive is removable over the onboard.
I also noticed that the classic screens are missing titles on the sub pages so while you may enter a memory details menu it doesn’t say that at the top of the page. Seems they are just expecting you to remember.
