  • Page 23: Standard Cmos Setup

    EP-3VBA BIOS Award’s ROM BIOS provides a built-in Setup program which allows user to modify the basic system configuration and hardware parameters. The modified data will be stored in a battery-backed CMOS, so that data will be retained even when the power is turned off. In general, the information saved in the CMOS RAM will stay unchanged unless there is a configuration change in the system, such as hard drive replacement or a device is added.
  • Page 24 EP-3VBA BIOS The menu displays all the major selection items. Select the item you need to reconfigure.
