Compatibility Concerns
DUPs are designed to confirm that all prerequisites are satisfied before applying
the update to your system. Each DUP checks to ensure the following:
• The logged-on user has root privileges.
• The DUP to be applied in the command is compatible with your target system.
• The DUP to be applied in the command is compatible with the operating
system running on your system.
• The device associated with the DUP is present on your system.
• The minimum required versions of related system software are running on
your system.
DUPs are designed with built-in error handling capabilities to ensure that the
preceding requirements are validated. If the conditions are not met, no
update occurs. DUPs also check for dependencies between BIOS and certain
ESM packages. The application design allows you to create groups of DUPs
and apply them to a wide range of systems. Additionally, if you only want to
verify that a given package can be applied to your system, you can invoke the
package by using the following CLI command:
./Packagename.bin -c for Linux
packagename.exe /c /s for Windows
