CMOS Setup Defaults

The VL-EBX-37 permits you to modify CMOS Setup defaults. This allows the system to boot up
with user-defined settings from cleared or corrupted CMOS RAM, battery failure or battery-less
operation. All CMOS setup defaults can be changed, except the time and date. CMOS Setup
defaults can be updated with the BIOS Update Utility. See the
for details.
Note:
If CMOS Setup default settings make the system unbootable and prevent the user
from entering CMOS Setup, the system can be recovered by switching to the
Backup BIOS.

After the CMOS RAM is cleared, the system will load default CMOS RAM parameters the next
time the board is powered on. The default CMOS RAM setup values are used in order to boot the
system whenever the main CMOS RAM values are blank, or when the system battery is dead or
has been removed from the board.
Custom default values will be used for CMOS restoration when available. Otherwise, factory
defaults will be used. Factory defaults can still be loaded when custom defaults have been
programmed by selecting "Reload Factory-Defaults and Restart" on the Exit tab, but CMOS
restoration will continue to use custom defaults as long as they are available.
To remove custom defaults, either re-program the BIOS or follow the "Saving CMOS Setup
Parameters as Custom Defaults" procedure below after selecting "Reload Factory-Defaults."

To save custom CMOS defaults, perform the following steps.
1. Configure CMOS Setup to your preferred custom default settings.
2. Install DOS onto one of the devices that has been configured as a boot device, or onto an
auxiliary boot device (such as a USB flash drive) that can be booted from using the Boot
Action Menu, and need not be configured in the Boot Device Prioritization list.
3. Copy FBU to this device.
4. Boot the VL-EBX-37 from this device. To boot from the auxiliary device using the Boot
Action Menu, press Ctrl-B during the memory count, or about twice per second after
power on. From the Boot Action Menu, select the auxiliary device to boot from it.
5. Run FBU and select "Save CMOS contents." A file named CMOS.BIN is created and
saved to the floppy.
6. Select the FBU option "Load Custom CMOS defaults."
7. Select the CMOS.BIN file and press the P key to program the new CMOS defaults.
8. Reboot the system. If FBU cleared CMOS RAM after the programming operation, the
new custom defaults will now be in effect.
