Dynamic BIOS Access
Dynamic BIOS Access allows you to change some of your system BIOS
settings. The changes do not go into effect until you reboot your system. Since
these changes are made to actual BIOS settings in the CMOS, the settings
remain active until you change them again or restore the CMOS to the default
settings.
