I installed an old Abit AB-BM6 motherboard today. When starting the computer, I will get the following error message:
CPU is unworkable or has been changed. Please recheck - CPU SOFT MENU
I have not managed to solve this problem. If I change BIOS settings to ignore errors, then this is not shown, but what may be the reason? There is some Intel Celeron CPU on the motherboard.
It means you need to check the CPU settings (bus speed and multiplier) in the BIOS. If these are wrong, the board will run in fail-safe mode (66MHz)
I have tried different settings for the CPU in BIOS, but after saving and restarting computer, they are always changed back to the default values. Somewhere I read that the battery replacement would help, but I'm not sure because the other settings are not changed.
How should the battery be removed from this kind of clip?
Your CMOS battery is dead. Remove and replace it. Don't pull on the metal clip, it will break. There is a bit of plastic on the side you can push on to remove the battery. It's a standard CR2032 3.3V coin-cell battery, easily found in most shops, even some corner stores.

If the battery is dead and the computer is plugged to the AC outlet, shouldn't it keep the settings in that case anyway? But I will replace the battery and test if it works. This battery is old I think.
