DUPs are available for the following software components:

• System BIOS

• Apply an individual update to a system by using an interactive command line interface (CLI).
• Install device drivers in interactive and non-interactive modes.
• Execute multiple updates for your system.
• Leverage your operating system's scheduling and software distribution utilities to apply updates remotely to any number of systems.
• Leverage Dell tools such as iDRAC, Dell System Update, Dell Server Update Utility and OpenManage Enterprise to facilitate the application of update packages.
