I have a problem with a DH77KC board (latest BIOS 0110) - I cannot clear CMOS settings.
When I press F9 in BIOS setup (maintenance mode) it asks me if I want to reset all settings to defaults. I click "Yes" and then the system hangs completely and I must do a hard reset after which settings are NOT reverted to defaults.
After that I removed the CMOS battery and left it out for ~12h (PSU power switch was OFF). I was pretty sure that would clear the settings for sure but it DID NOT. Only the clock got reset.
How do I clear CMOS settings completely on this board? Any ideas?
