CMOS central management and extracting CMOS settings to the file server for distribution
CMOS central
management allows ThinOS administrators to easily manage CMOS settings
for large deployments of thin client devices using central configuration
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.
To prepare a reference drive containing BIOS
version 3.0D or later:
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.
Save your CMOS settings.
Restart your thin client device.
To create a CMOS INI file in a file server:
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.
Type the following name in the cmos.ini
file: Device=cmos Action=extract.
To reboot the reference device to the file
server containing the CMOS INI file:
On the thin client you want to use as a
reference device, start the thin client.
In the Login dialog box, enter the
credentials you need to access the cmos.ini file.
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.
To prepare the file server containing the CMOS
INI file for distribution:
Write the following line in the cmos.ini
file for distribution on your file server: Device=cmos Action=restore.
Save the file.
Log in to all target device to the file server
containing the CMOS INI file:
Start the thin client devices for which
you want to distribute the reference device CMOS settings.
To access the cmos.ini. file, enter your
credentials in the Login dialog box.
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).
