What Are The Available Command-Line Switches For BIOS Management?  

Command-line switches are often used by IT Professional when updating the Dell BIOS on the latest model of Latitude, Optiplex and Precision Workstation systems. For more information on these options and the appropriate syntax to utilize them, please see below.
 

Utilizing The Recommended Windows Switches

Below is an example output from the Latitude E6520 BIOS executable "E6520A05.exe". General usage:

Typical Syntax: Filename.exe [/<option1>[=<value1>]] [/<option2>[=<value2>]]    Option - Description: (none) - Display of graphical user interface for guided update.
/? or /h - Displays this Dell System BIOS Update usage information.
/s - Suppresses all graphical user interfaces of the BIOS System BIOS Update.
/l= - Define a specific path for the Dell System BIOS Update log file.
/f - Override a soft dependency error returned from the Dell System BIOS Update. NOTE: Requires /s option.
/r - Reboot the system to complete the update. NOTE: Requires /s option.
/p= - Provide the BIOS password (if needed) to perform the BIOS update. Example(s):
  • Update the system silently: Filename.exe /s
  • Change from the default log location (example target path:  C:\my path with spaces\log.txt) Filename.exe /l="C:\my path with spaces\log.txt"
  • Force update to continue (even on "soft" qualification errors): Filename.exe /s /f
If the ability to remotely update the Dell BIOS across a network is desired, the Dell Client Configuration Toolkit (CCTK) is recommended. CCTK is available for download from the Dell Support website for the systems in use.
 
The complete list of switches and their descriptions can be obtained by running the executable (filename.exe /) with either the "/?" or the "/h" switch from the command prompt in Windows.
