I'm having an issue with the DZ77RE-75K motherboard where, after updating the BIOS, USB does not work until the computer boots in to Windows.
If I update the BIOS from v49 to v53 or v59 the motherboard will not recognize USB input until Windows boots.
This means I can not access the motherboard BIOS, Network boot or BIOS update functions unless I use a PS2 keyboard.
I have tried updating the BIOS using the .exe file and also using the .ROM file w/the F7 prompt. The BIOS updates successfully, but USB does not function until Windows starts.
I have an Acronis recovery prompt that I sometimes need to access before Windows starts and using a PS2 keyboard permanently is not an option.
