CMOS management

This appendix includes general CMOS management information for use with Cisco VXC 2112/2212 BIOS version 1.0B-0407 or later.


Note


The 1.0B-0407 BIOS version appears in the interface event log as 1.0B.

Depending on the method of distribution you want to use, complete one of the following:

Extract CMOS settings to the file server for distribution


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 that logs into the file server that contains the cmos.ini and its extract and restore commands will be subject to those commands (CMOS overwrites).


CMOS central management allows WTOS administrators to easily manage CMOS settings for large deployments of zero clients using central configuration methodologies.

This case example uses Cisco VXC 2112/2212 BIOS version 1.0B-0407. However, you can use these instructions for other supported BIOS versions.

Procedure
    Step 1   Prepare a Reference Device containing BIOS version 1.0B-0407 or later:
    1. On the zero client you want to use as a Reference Device (the reference device will be the golden image you will use to distribute to other zero clients), enter the BIOS Setup Utility (during boot, press and hold the Delete key, enter the password Fireport—this is case sensitive—and press Enter) and configure the CMOS settings you want (supported CMOS settings include: AutoPower, BootOrder, P-key setting, BiosPassword—and for BIOS version 1.0B-0407 or later the WakeOnLAN setting).
    2. Save your CMOS settings before exiting the utility.
    3. Shut down the zero client.
    Step 2   Prepare a File Server containing a CMOS INI File:
    1. On your file server, create a cmos.ini file and place it in the wnos directory/folder under the file server ini directory (be sure the wnos directory on the file server has upload privilege).
    2. In the cmos.ini file, write the following line:

      Device=cmos Action=extract

    Step 3   Reboot the Reference Device to the File Server containing the CMOS INI File:
    1. Start the zero client you want to use as a Reference Device.
    2. In the Login dialog box, enter the credentials you need to access the cmos.ini file.
    3. After login, you can open the event log (System Information icon > System Information dialog box > Event Log tab) to view a CMOS: Extract To ZC0_cmosxxxxx 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 Cisco VXC 2112/2212 BIOS version 1.0B-0407 example, the CMOS central management file name would be ZC0_cmosxxxxx. These CMOS settings are now ready for distribution to other zero clients.
    Step 4   Prepare the File Server containing the CMOS INI File for Distribution
    1. On your file server that contains the cmos.ini file for distribution, write the following line in the cmos.ini file:

      Device=cmos Action=restore

    2. Save the file.
    Step 5   Login All Target Devices to the File Server containing the CMOS INI File
    1. On all of the target zero clients that you want to distribute the Reference Device CMOS settings, start the zero client.
    2. In the Login dialog box, enter the credentials you need to access the cmos.ini file.
    3. After login, you can open the event log (System Information icon > System Information dialog box > Event Log tab ) to view a CMOS: Restore From ZC0_cmosxxxxx event. This means that your CMOS central management file (containing the CMOS settings from your Reference Device) has been written to your target zero client.
      Caution   

      After your target zero clients contain the CMOS settings you want, do not sign in to the file server containing the cmos.ini file with the restore action (unless you want to redo the restore process). Administrators can remove the cmos.ini file to prevent unwanted CMOS overwrites.


    Extract CMOS Settings to a USB key for distribution

    CMOS local management allows WTOS administrators to easily manage CMOS settings for small deployments of zero clients using USB Key distribution methods.

    This case example uses Cisco VXC 2112/2212 BIOS version 1.0B_SPC001-0407. However, you can use these instructions for other supported BIOS versions.

    Procedure
      Step 1   Prepare a Reference Device containing BIOS version 1.0B-0407 or later:
      1. On the zero client you want to use as a Reference Device (the reference device will be the golden image you will use to distribute to other zero clients), enter the BIOS Setup Utility (during boot, press and hold the Delete key, enter the password Fireport—this is case sensitive—and press Enter) and configure the CMOS settings you want (supported CMOS settings include: AutoPower, BootOrder, P-key setting, BiosPassword—and for BIOS version 1.0B-0407 or later the WakeOnLAN setting).
      2. Save your CMOS settings before exiting the utility.
      Step 2   Extract the CMOS Settings to a USB Key:
      1. On the zero client you want to use as a Reference Device, attach a formatted USB Key (to format on Windows 7 computers for example: attach the USB Key, right-click on the USB key, select Format, click Restore device defaults, select Quick Format, and click Start).
      2. Use the Extract CMOS to USB GUI feature of WTOS to extract the CMOS settings to the USB Key:
        • Classic Desktop: Right-click the desktop and select Extract CMOS to USB.
        • Cisco VXC Desktop: On the General tab of the System Tools dialog box (System Settings icon > System Tools > General tab ), click Extract CMOS to USB.
      3. After successful extraction (you will see a pop-up message: CMOS: extract to ZC0_cmosxxxxx), properly eject and detach the USB Key. The CMOS settings on the USB Key are now ready for distribution to other zero clients.
      Step 3   Restore the CMOS Settings to Your Target Devices
      1. On all of the target zero clients that you want to distribute the Reference Device CMOS settings, start the zero client.
      2. Use the Restore CMOS from USB GUI feature of WTOS to write the CMOS settings from the USB Key to the target zero client:
        • Classic Desktop: Right-click the desktop and select Restore CMOS from USB.
        • Cisco VXC Desktop: On the General tab of the System Tools dialog box (System Settings icon > System Tools > General tab), click Restore CMOS from USB.
      3. After successful restoration (you will see a pop-up message: CMOS: restore from ZC0_cmosxxxxx), properly eject and detach the USB Key. The CMOS settings on the USB Key are now written to your target zero client.
