Administrator Guide

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. Type 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. 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 file.
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 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 D10D BIOS version 3.0D, the CMOS central management file name would be
D10D_cmos.3.0D. These CMOS settings are now ready for distribution to other thin clients.
4. To prepare the file server containing the CMOS INI file for distribution:
a. Write the following line in the cmos.ini file for distribution on your file server: Device=cmos Action=restore.
b. Save the file.
5. Log in to all target device to the file server containing the CMOS INI file:
a. Start the thin 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 D10D_cmos.3.0D event. This means that your central management file 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 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 from unwanted CMOS overwrites.
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 thin client device that logs in to the file server that
contains the cmos.ini and its extract and restore commands are subject to those commands (CMOS overwrites).
For more information about the INI parameter Device=cmos, see Dell Wyse ThinOS INI Reference Guide.
CMOS local management and extracting CMOS
settings to a USB key for distribution
CMOS local management allows ThinOS administrators to easily manage CMOS settings for small deployments of thin clients
using USB key distribution methods. 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.
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.
Configure 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 extract the CMOS settings to a USB key.
a. Attach a formatted USB key on the thin client device which you want to use as a reference device. For example, to
format on Windows 7, attach the USB Key, right-click the USB key, select format, click Restore device defaults, select
Quick Format, and then click Start.
b. Use the extract CMOS to USB GUI feature of ThinOS to extract the CMOS settings to the USB key. On Classic Desktop,
right-click the desktop and select Extract CMOS to USB. On Wyse Zero desktop, in the General tab of the System
Tools dialog box (System Settings icon > System Tools > General tab), click Extract CMOS to USB.
c. Once extraction successful you see a pop-up message: CMOS: extract to D10D_cmos.3.0D, properly eject and detach
the USB key. The CMOS settings on the USB key are now ready for distribution to other thin clients
3. To restore the CMOS settings to your target devices:
