Quick update- I got into BIOS screen by pressing F2 on a USB keyboard. I tried to get into it with the Bluetooth keyboard, but it didn't work. I got into BIOS screen with a USB keyboard, but the BIOS screen is messed up (options are scattered). I'm not sure if it have anything to do with my 56" HDTV screen. Again, everything work fine and it playback all BD files in hi-def video/audio on the same 56" HDTV flawless. I'm using Asrock E350M1/usb3 bios version p1.20.
