So far this bios seems ok, but I did have an issue during flash.
After first flash I could save settings to profile and recall them but when I pressed F10 to "save & resest" the system would only reboot to default settings. After I tried this a few times I flashed back to 1602 and all of my profiles disappeared. I reflashed again back to 1701 and still had no profiles so I began new profiles and everything works fine now.
Still probably too early to tell but I think this bios is a keeper.
