Table 22. Parameters for a xen.ini File (continued)
Parameter Description
If optimize=yes and the camera does not support the 320 x 240 at
10 fps settings, an error will be present in the Event Log of ThinOS
Lite.
If optimize=no then the individual settings in width, height, and fps
will be used as long as the camera supports them.
Disable— When you specify Disable=yes, the device is disabled.
For example, the Camera tab in peripherals setting is disabled,
the Exclude video devices option in Global Connection Settings
is disabled. The device cannot be accessed at local and remote
sessions.
Default—Enables you to set the default camera device settings.

Not supported on ThinOS Lite 2.0
CMOS management (extract and restore cmos settings).
ThinOS Lite (C00X) BIOS version 1.0B_SPC001-0407 or later.
ThinOS Lite Pro (R00LX) BIOS version 1.0H_SPC-0T51 or later.
For more information, see BIOS Management.
Extract — For extract action, CMOS content is saved to the file:
$PF_cmos.$VER
NOTE:
● $PF — denotes the name of the platform such as C10LE,
C00X, R10L, R00LX, and VL10
● $VER — denotes the version of BIOS such
as 1.0B_SPC001(1.0B_SPC001-0407), 1.0B-0407(Zilch),
1.0H_SPC-0T51(R10L, R00LX), 1.19R(VL10)
Restore
— For restore action, CMOS content is updated from the
file: $PF_cmos.$VER
The file is checked thoroughly and protected from corruption
1. The content is wrapped in a file header, including a field of magic
number, checksum, timestamp, length and platform name.
2. The content is first checksum and then AES encrypted during
save operation.
3. On restore operation, if the CMOS timestamp that is stored in
nvram matches the timestamp on the file, the cmos content will
not be written every time to avoid wearing out the cmos chip.
For usage of this feature, there should be a special INI user name
like "cmos". The associated ini/cmos.ini should include one line as
"Device=cmos Action=extract".
NOTE:
We do not recommend "Device=cmos Action=extract"
to be written in global INI file, like xen.ini. This will take no
effect, if it is written in global INI file.
After the administrator configures the CMOS on a template unit,
the administrator should sign on to "cmos" account on ThinOS Lite
to get the CMOS content saved to the cmos file on writable File
Server xen directory.
Then the xen.ini must be configured with "Device=CMOS
action=restore", so all target units will get updated with the same
CMOS setting as template unit after reboot.
Once the restore action is finished, both "Device=cmos
Action=extract" and "Device=CMOS action=restore" must be
removed from the related INI files.
