DEVICE=UsbTrace vid_pid={device vid/pin hex format} [max_len=500] FactoryDefault={no, yes} PXEBootSupport-If yes is specified, device allows operating system to boot from PXE. If no is specified, the operating system cannot boot device from PXE For extract action, CMOS content is saved to file $PF_cmos.$VER $PF-name of Dell BIOS platform, including X10 and A10Q $VER-version of BIOS, like 1.2.2. With ThinOS log, CMOS, extract to $PF_cmos.$VER For restore action, CMOS content is updated from file $PF_cmos.$VER With a syslog, CMOS: restore from $PF_cmos.$VER The file is strongly checked and protected from corruption. The content is wrapped in a file header, including a field of magic number, checksum, timestamp, length and platform name. The content is first checksum and then AES encrypted during save operation. During restore operation, if the CMOS timestamp (stored in nvram) matches the timestamp on the file, 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 file, like wnos.ini, and it will take no effect if it has been written in global INI file). 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 configured 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 file on writable File Server wnos directory. Then, the wnos.ini should be configured 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 finished, both the "Device=DellCmos Action=extract" and "Device=DellCmos action=restore" must be removed from the related INI files. The usage of other settings is self-explanatory. The only condition to use the setting is the BIOS GUI has such settings. 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. 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 firmware change; however, you can set to no and then reboot so the option will be initialized again. 50 Parameters for wnos INI, {username} INI, and $MAC INI files

PXEBootSupport
—If yes is
specified,
device allows operating system to boot from
PXE. If no is
specified,
the operating system cannot boot device from PXE
For extract action, CMOS content is saved to
file
$PF_cmos.$VER
$PF—name of Dell BIOS platform, including X10 and A10Q
$VER—version of BIOS, like 1.2.2.
With ThinOS log, CMOS, extract to
$PF_cmos.$VER
For restore action, CMOS content is updated from
file
$PF_cmos.$VER
With a syslog, CMOS: restore from
$PF_cmos.$VER
The
file
is strongly checked and protected from corruption.
The content is wrapped in a
file
header, including a
field
of magic number, checksum,
timestamp, length and platform name.
The content is
first
checksum and then AES encrypted during save operation.
During restore operation, if the CMOS timestamp (stored in nvram) matches the
timestamp on the
file,
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
file,
like wnos.ini, and it will take no
effect
if it has been written in global INI
file).
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
configured
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
file
on writable File Server wnos directory.
Then, the wnos.ini should be
configured
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
finished,
both the "Device=DellCmos Action=extract" and
"Device=DellCmos action=restore" must be removed from the related INI
files.
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
firmware
change; however, you can set to no
and then reboot so the option will be initialized again.
