I have an Asus ROG Z68 which has UEFI Bios but I did not install windows as an UEFI install. I do not see Bios Time in Task Man either. I am not sure if you need a Z77 which that quick boot setting to see it.
I will just update.. my asrock z68/usb3 have updated its bios so I have timer too on start up. Have ultra boot as well but my GPU bios GOP don't support it :O
i disabled it and went back to legacy,couldn't tap keyboard fast enough to get to bios before windows started,in case i needed to boot from dvd,couldn't get to uefi from within win settings because i had changed graphics card and power supply,i would just get a continues beep because of safe boot,
