Client System Automated BIOS Update Command Line Syntax

This article defines the command line instructions to perform an automated BIOS update on Dell systems

Command line options exist that allow experienced users to perform a BIOS update as a background process with no user interaction required.

Note: While these options are available, their usage is not recommended by Dell as they may result in unexpected errors or inadvertently regressing the BIOS to an undesired version.

These options, and their appropriate syntax, are as follows:

1. ‘nopause’: Install with no user interaction (/s option for UEFI BIOS updates)
   • Syntax: package.exe /nopause (or package.exe /s for UEFI)

• ‘noreboot’: Suppresses the required reboot. (A reboot must occur to complete the BIOS update, so the update will be completed on the next system restart, and the end user will be unaware of the update.)
  • Syntax: package.exe /noreboot (or package.exe /s /f for UEFI)
