see Installation Order of DUPs.

Question: How will I know when there are new DUPs available for my systems?

Answer: You can check dell.com/support for updates or register for the File Watch Service at dell.com to receive

automatic notification for upgrades to the system.

Question: Why do BIOS and firmware updates fail to re-apply (update to the same version), even when using the force

(/f) option in CLI mode?

Answer: Incase you are facing issues with the CLI mode, run DUPs in the GUI mode and confirm the re-application.

Question: Why does my system only execute one of the CLI options that I entered in a command string?

Answer: Only certain CLI options can be used simultaneously. When invalid combinations of CLI options are entered in a

single command string, only the option with the highest priority is executed. For details on which commands can be used

together for different operating system, see Command Line Interface Reference .

Question: How do I verify that the DUPs that I have downloaded has a digital signature?

Answer: In Windows Explorer, locate the DUP that you want to verify and right-click the filename. Click Properties in the

pop-up window. If you see the Digital Signatures tab in the Properties window, the DUP has a digital signature. If that

tab is not displayed, the DUP is not signed. See Verifying the Digital Signature on Windows for additional information.

Question: Why can’t I use a signed DUP with my current release of DUP?

Answer: DUPs released on 3rd quarter of 2005 and later are digitally signed.
