UEFI BIOS
UEFI is an acronym for Unified Extensible Firmware Interface. The UEFI specification defines a new model for the interface
between personal computer operating systems and platform firmware. The interface consists of data tables that contain
platform related information, plus boot and runtime service calls that are available to the operating system and its loader.
Together, these provide a standard environment for booting an operating system and running pre-boot applications. One of the
main differences between BIOS and UEFI is the way applications are coded. Assembler was used if functions or applications had
to be coded for the BIOS while a higher level language code will be used to program the UEFI.
Dell UEFI BIOS implementation will supersede the existing two different sets of BIOS in the portables and desktop products into
one single UEFI BIOS moving forward.
Important Information
There is no difference in between the conventional BIOS and the UEFI BIOS unless the UEFI option is checked in the 'Boot
List Option' setting in the BIOS page. This will allow the user to create a UEFI boot option list manually without affecting the
existing boot priority list. With the implementation of UEFI BIOS, the changes are more related to the manufacturing tools and
functionalities with very minimal impact to the customer's usages.
Few things to remember are:
●
If customers have a UEFI boot media and ONLY if they have UEFI boot media (either in the optical media or via USB
storage), the one-time boot menu will show an additional section listing the UEFI boot options. If they don't have UEFI boot
media attached, they will never see this option. Almost all will never get to see this option unless the UEFI boot option is
specified manually through the 'Boot Sequence' settings.

How to change Service Tag/Owner Tag?
When the service technician replaces a system board, he's required to set the service tag upon the system starts up at one
time off basis. Failure to set a service tag may result system battery not being able to charge. Therefore, it is very important
that the service technician set the correct system service tag. If a wrong service tag is set, there's no way to reset it and
the technician will have to place order for another system board replacement.
