WARNING: CMOS Battery Damage
Replace your system’s CMOS RAM battery only with the identical CR-2032 3V Lithium-Ion coin cell (or equivalent) battery
type to avoid risk of personal injury or physical damage to your equipment. Improper installation might cause battery to
explode. Always dispose of used batteries according to the manufacturer’s instructions, or as required by the local
ordinance (where applicable). The damage due to not following this warning will void your motherboard’s manufacturer
warranty.

ATTENTION: Incorrect BIOS Setup
If you do not know how to handle BIOS setup or how to set it up properly, it is strongly advisable that you do not modify
