did you select UEFI boot in the visual bios, or legacy bios?
if you go into the legacy bios make sure UEFI boot and Legacy boot are both enabled.
thats the point. After the bios upgrade and some playing with setting. I had left Legacy boot accidentally disabled in the legacy bios menu and that caused the beep of death.
Now it is ok, and with new bios I can boot linux kernel in UEFI mode.
glad it worked, I'm hoping for a UEFI fix for my DZ77BH-55K, as Windows works fine with UEFI, but Linux Kernel doesn't.
