Tutorial Dskflash.exe
Preface This document gives a very short overview and some usage examples of the command line executable Dskflash.exe. Dskflash.exe is part of the Lifecycle Management software product "DeskView Client" including more tools and WMI classes to manage Fujitsu Client Computing Devices. Further information on the complete product, including the detailed manual, can be found online. See the Additional Information chapter.
Updating the BIOS and making changes to the BIOS Setup should be handled with care and system knowledge. The tool does request administrative privileges to execute. Making careless changes in the BIOS setup or flashing a BIOS image together with improper settings poses a certain risk to compromise the system and prevent booting of the current OS installation. For detailed Information review the chapter "BIOS Management (Archive & Update)" inside the DeskView Client User Manual.
Regarding the BIOS settings and their effects on a particular system, be sure to consult the system or mainboard manual.
Find download links in the Additional Information chapter.
Download and Installation You can install Dskflash.exe permanently as part of DeskView Client, using the msi package. Another option is to use the "Instant" package. This package runs an install / uninstall procedure within one call. This might be preferred if WMI and other features of DeskView Client are not needed. The instant package can be used on Windows PE for pre-installation usage too. Administrators can choose to distribute the tools via their companywide management toolset or offer it on a common network share. Installation and execution will need administrative privileges.
Common procedures and command line switches With DeskView Client, tools are installed under the % ProgramFiles(x86)% Fujitsu\DeskView directory per default. Msi Setup creates a %DESKVIEW% environment variable, which can be used even if another installation path has been chosen manually. To run an executable, you can open a cmd window as administrator and call the tool with e.g.: %DESKVIEW%\DeskFlash\Dskflash.exe /?
Show help, options and syntax: /?
Calling a command line tool with the parameter /? shows help and syntax. You can pipe it into a text file to have a document easier to read as inside the cmd window. The syntax is in EBNF format with optional parameters in [] brackets and placeholders for items listed in the help placed in . Dskflash.exe /? > Dskflash_Help.txt
C:\>"%DESKVIEW%\DeskFlash\dskflash.exe" /?
Show Errorlevels: /E
Produce a list of Errorlevels and explanation. These are the return codes of the executables, which could be tested inside batches or scrips as %ERRORLEVEL% Part of this output: C:\>"%DESKVIEW%\ DeskFlash\dskflash.exe "/E
The BIOS Update procedure
With modern Desktop and Notebook platforms, the BIOS will be updated during the BIOS Post cycle after a reboot. Dskflash.exe will check the BIOS image and provide it then to the BIOS interface. This is only a staging mechanism; the real Update will be done after an OS reboot. The appropriate Errorlevel will be 400 to indicate that a reboot is necessary and no immediate update action has happened when using the switch /nrb. Dskflash.exe also provides a checking mechanism after the reboot. There is no password needed for a BIOS Firmware Update, even if a BIOS Admin Password was set. The password will remain. In case of a BIOS Update in combination with settings or simply a Settings Update the password needs to be provided if one is set in the BIOS.
How to update a BIOS firmware
A frequent usage scenario would be to update the BIOS, where a BIOS.update package file (*.bup) is located in the local directory C:\UPDATE. The system may initiate a reboot if required as indicated by /arb or /allowreboot. DSKFLASH /UPD /WD=C:\UPDATE /O=BIOS.BUP /ARB
There is also an automatic search feature built into dskflash.exe. DskFlash.exe will search for a suitable update file in a folder on the shared network drive \\Server\Share. DSKFLASH /UPD /WD=\\SERVER\SHARE /ARB

Tutorial Dskflash.exe
How to archive settings from a specified machine The archive file will be saved onto the shared network drive \\Server\Share. The computer name and the mainboard will be used automatically in the file names. The archive file includes all NVRAM settings, the Bootorder settings and the Passwords all in an encrypted format. DSKFLASH /ARC /WD=\\SERVER\SHARE /O=ARCHIV_#name#_#system#.nvux For systems using older CPUs than Intel 8th generation, please refer to the DeskView Client User Manual.
How to update settings from an archived settings file The settings from the archive.nvux file that is located on the shared network drive \\Server\Share are applied. If a BIOS Password was set on the machine, you need to add the switch /PWD to the commandline and provide the correct Password.
DSKFLASH /NVU /WD=\\SERVER\SHARE /O=ARCHIV.nvux /ARB /PWD=******
How to combine archived settings and a Fujitsu Original BIOS Update file The archived BIOS settings of the nvux file are combined with the original Fujitsu BIOS file that you can download from the Fujitsu Support website. The combined BUP file can then be used to update the BIOS at the same time as the settings.
DSKFLASH /MAKE /O=combined.bup /CINP=archive.nvux /BINP=original_bios.bup
How to update the BIOS together with settings at the same time Archive the BIOS as previously described and use DSKFLASH /MAKE to create a combined.bup from the nvux file and the original Fujitsu BIOS file that you can download from the Fujitsu Support website. During an update, the BIOS is updated according to the original BIOS file and the settings from the nvux archive file are applied. Please note that a Password needs to be provided on the commandline to update the settings on the target machine. The switch /ov is needed in case the BIOS that is included is already on the system or needs to be downgraded to an earlier version.
DSKFLASH /UPD /WD=\\SERVER\SHARE /O=combined.BUP /OV /ARB /PWD=*****
How to check for the Last Action Status Dskflash.exe can also check whether an update process during the Post cycle was successful.
