Dell Command | Update uses update packages to determine the latest updates for a system. An update package contains feature enhancements or changes in BIOS, firmware, drivers, applications, and software. Usually, the update is self-sufficient and runs the preinstallation and applicable dependencies; however, the update may be dependent as described here:
For example, consider that your system has version A01 of BIOS installed. Version A05 is the latest available update, but it requires version A03 as a prerequisite. Dell Command | Update updates the system to version A03 before allowing an update to version A05.
NOTE: It takes more than one update cycle for the system to be updated to one or more latest available versions, which are initiated by the user.
For example, consider that your system needs a firmware update. To update system firmware, you must first update the system BIOS to a required minimum version. Dell Command | Update updates the system BIOS to the required version before updating the system firmware.
NOTE: When the application initiates a system update, it takes more than one update cycle for the system to be updated to one or more latest available versions.
NOTE: If the update you want to install has a dependency, Dell Command | Update notifies you during the update process with an information alert.
NOTE: Non-dependent and inter-dependent updates are installed prior to intra-dependent updates.
