The System BIOS software searches the FBD for the unterminated string
“RadiSysCMOS--->” at power-up. This footprint marks the beginning of the CMOS
parameter block storage structure. The structure contains a 16-bit CRC of the CMOS
RAM data that is calculated at backup time and recalculated at restoration time. If the
CRC verification fails, the restoration is skipped.
If the System BIOS succeeds in restoring a backup image to CMOS RAM, the system
beeps 1 long and 5 short tones.
Restoration is inhibited for warm boots (CTRL-ALT-DEL from DOS) and when a
restore is attempted but no valid CMOS image exists in the FBD.
Save Changes & Exit
This option is used to save into CMOS the values that have been entered, then reboot.
Discard Changes & Exit
This option is used to discard the changes just made and revert to the state when Setup
was entered. The system reboots with the old values.
Get default values
This option is used to reset the Setup values to the original, default values that were
set at the factory, before any suppliers or other end users made changes.
Backup CMOS to Flash
This option is used to immediately save current Setup settings from CMOS into flash.
This is useful for backing up complicated setups.
Restore CMOS from Flash
This option is used to immediately restore CMOS settings from flash.
Restore Condition
This option is used to determine under what conditions the System BIOS restores
CMOS RAM from the FBD when booting. The restore conditions are: “Always”,
“Never”, and “Bad CMOS”. The default is “Bad CMOS”.
