Setup Guide

Table 7. General Settings: wnos.ini files, {username} INI, and $MAC INI Files (continued)
NOTE: USB, keyboard, and mouse always work regardless of being
specified or not.
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.
