Parameter Description
The content is wrapped in a le header, including a eld of magic number, checksum,
timestamp, length and platform name.
The content is rst checksum and then AES encrypted during save operation.
During restore operation, if the CMOS timestamp (stored in nvram) matches the
timestamp on the le, the cmos content is not 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=DellCmos Action=extract"
(Pleaset note: "Device=DellCmos Action=extract" is not suggested to be written in
global INI le, like wnos.ini, and it will take no eect if it has been written in global INI
le). And "CurrentPassword" is must be required if device's BIOS password is existed
regardless extract or restore action.
e.g: Device=DellCmos CurrentPassword= xxxxx Action=restore
After the administrator congured the CMOS on a template unit, the administrator
should sign on to "cmos" account on WTOS to get the CMOS content saved to the
cmos le on writable File Server wnos directory.
Then, the wnos.ini should be congured with "Device=DellCmos action=restore", so all
target units will get updated with the same CMOS setting as template unit after
reboot.
Once the restore action is nished, both the "Device=DellCmos Action=extract" and
"Device=DellCmos action=restore" must be removed from the related INI les.
The usage of other settings is self-explanatory. The only condition to use the setting is
the BIOS GUI has such settings.
DEVICE=UsbTrace
vid_pid={device vid/pin hex format}
[max_len=500]
Specify the WTOS to trace USB device data to ftp or USB disk. For "vid_pid", device
Vendor ID and Product ID hex value, and VID is high 16 bit while Product ID is low 16
bit.
Allows to trace maximum of eight devices at one time. For "max_len", set a max len for
capturing each USB transfer data. Default value is 128. After you set this, you need to
set option in Trouble shooting to start tracing the USB device data.
FactoryDefault={no, yes}
Default is no.
Yes/no option to reset the system settings to factory default. This parameter, when set
to yes, is only initialized once for each rmware change; however, you can set to no
and then reboot so the option will be initialized again.
NOTE:
If the FactoryDefault parameter value is changed to yes, the thin client will
reboot without notice to the user.
*Include=path/lename
For {username}.ini le only. Species to include another INI le at the position of this
parameter. Only one level of including is allowed (no nesting) and only for a
{username}.ini le.
KeySequence={no, yes}
[Ctrl+Alt+Del={no, yes}]
[Ctrl+Alt+Up={no, yes}]
[Ctrl+Alt+Down={no, yes}]
KeySequence — Yes/no option to enable the following supported combined keys
options.
KeySequence=yes enables all of these options, each having a default of yes or no as
noted that you can change individually to the setting desired.
KeySequence=no disables all of these options regardless of the individual settings.
