Administrator Guide

NOTE: These BIOS settings are not applicable to Wyse 3010 thin client and Wyse 3020 thin client, as there is no BIOS on
ARM platform. To access the WLOADER on an ARM platform, press the power button for about four seconds until the
power light turns green, and then press the Delete key.
CMOS central management and extracting CMOS settings to the le
server for distribution
CMOS central management allows ThinOS administrators to easily manage CMOS settings for large deployments of thin client
devices using central conguration methodologies. Wyse 5010 thin client with ThinOS (D10D) is considered here as an example. The
following instructions are for Wyse 5010 thin client with ThinOS (D10D) BIOS version 3.0D. However, the instructions are also
applicable for other supported hardware platforms and BIOS versions.
1. To prepare a reference drive containing BIOS version 3.0D or later:
a. The reference device is a golden image you use to distribute to other thin client devices. To use reference drive, enter the
BIOS setup utility. Press the
Delete key, enter the password — Fireport (case sensitive) and press Enter. Congure the
CMOS settings, includes Auto Power, Boot Order, P-key setting, and BIOS Password.
b. Save your CMOS settings.
c. Restart your thin client device.
2. To create a CMOS INI le in a le server:
a. In the le server, create a cmos.ini le and place it in the wnos directory/folder under the le server ini directory. Make sure
that wnos directory on the le server has upload privilege.
b. Type the following name in the cmos.ini le: Device=cmos Action=extract.
3. To reboot the reference device to the le server containing the CMOS INI le:
a. On the thin client you want to use as a reference device, start the thin client.
b. In the Login dialog box, enter the credentials you need to access the cmos.ini le.
c. After login, to view the Event Log tab, do the following:
Click System Information icon → System Information dialog box → Event Log tab.
You can open the event log to view a CMOS: extract to D10D_cmos.3.0D event. This means that the CMOS central
management le (containing the CMOS settings from your Reference Device) is now copied to the wnos directory/folder on
the le server. As this is a D10D BIOS version 3.0D, the CMOS central management le name would be D10D_cmos.3.0D.
These CMOS settings are now ready for distribution to other thin clients.
4. To prepare the le server containing the CMOS INI le for distribution:
a. Write the following line in the cmos.ini le for distribution on your le server: Device=cmos Action=restore.
b. Save the le.
5. Log in to all target device to the le server containing the CMOS INI le:
a. Start the thin client devices for which you want to distribute the reference device CMOS settings.
b. To access the cmos.ini. le, 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 D10D_cmos.3.0D event. This means that your central management le containing the
CMOS settings from your reference device is copied to the targeted thin client devices.
NOTE: After you target your thin client devices contain the CMOS settings you want, do not log in to the le server
containing the cmos.ini le with the restore action (unless you want to redo the restore process). Administrators can
remove the cmos.ini le to prevent from unwanted CMOS overwrites.
NOTE: It is recommended to initially complete these procedures on a le server designated to test the success of
your CMOS central management settings/process. While the central conguration method can be used to enforce
your CMOS settings in a production environment, be aware that any thin client device that logs in to the le server
that contains the cmos.ini and its extract and restore commands are subject to those commands (CMOS
overwrites).
