CMOS Central Management—Extracting CMOS
Settings to the File Server for Distribution
CMOS Central Management allows ThinOS Lite administrators to easily manage CMOS settings for large deployments of zero
client devices using central configuration methodologies.
The following are the steps for extracting CMOS Settings to the File Server for Distribution for C00 BIOS version
1.0B_SPC001–0407:
1. To prepare a Reference Drive containing BIOS version 1.0B_SPC001-0407 or later:
a. The Reference Device is a golden image you use to distribute to other zero client devices. To access Reference Drive,
enter the BIOS Setup Utility. Press the Delete key, enter the Password — Fireport (case sensitive) and press Enter.
Configuring the CMOS settings, includes AutoPower, BootOrder, P-key setting, BiosPassword.
b. Save your CMOS Settings.
c. Restart your zero client device.
2. To create a CMOS INI File in a File Server:
a. In the file server, create a cmos.ini file and place it in the wnos directory/folder under the file server ini directory. Make
sure that wnos directory on the file server has upload privilege.
b. Enter the following name in the cmos.ini file:Device=cmos Action=extract.
3. To reboot the Reference Device to the File Server containing the CMOS INI File:
a. Start the zero client, FOR which you want to use a Reference Device.
b. In the Login dialog box, enter the credentials you need to access the cmos.ini file.
c. After login, to view Event Log tab.
To view Event Log, click System Information icon, System Information dialog box is displayed. In the System Information
dialog box, select Event Log tab.
You can open the event log to view a CMOS: extract to C00_cmos.1.0B_SPC001 event. This means that the CMOS
central management file (containing the CMOS settings from your Reference Device) is now copied to the wnos
directory/folder on the file server. As this is a C00 BIOS version 1.0B_SPC001-0407 example, the CMOS central
management file name would be C00_cmos.1.0B_SPC001. These CMOS settings are now ready for distribution to other
zero clients.
4. To prepare the File Server containing the CMOS INI File for Distribution:
a. Start the zero client devices for which you want to distribute the Reference Device CMOS Settings.
b. To access the cmos.ini file, enter your credentials in the Login dialog box.
c. To open Event Log, click System Information icon. In the System Information dialog box, select Event Log tab.
You can view the CMOS: restore from C00_cmos.1.0B_SPC001 event. This means that your Central Management file
containing the CMOS settings from your Reference Device is copied to the targeted zero client devices.
NOTE:
After you target your zero client devices contain the CMOS settings you want, do not log in to the file server
containing the cmos.ini file with the restore action, unless you want to redo the restore process. Administrator can
remove the cmos.ini file to prevent from unwanted CMOS overwrite.
NOTE: It is recommended to initially complete these procedures on a file server designated to test the success of
your CMOS central management settings/process. While the central configuration method can be used to enforce your
CMOS settings in a production environment, be aware that any zero client device that logs in to the file server that
contains the cmos.ini and its extract and restore commands are subject to those CMOS overwrite.
NOTE: The above procedure is also applicable for other supported BIOS versions.
