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.
A 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. Customers can view this option If they have UEFI
boot media attached, and 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, its required to set the service tag when the system restarts. Failure to set a service
tag may result in 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, then the technician will have to place the order for another system board replacement.
How to change Asset tag information?
To change the Asset tag information, we can use one of the following software utilities:
• Portables Technology Dell Command Configure toolkit-
Customers may also report that after a motherboard replacement, the asset field is already populated in the system BIOS, and needs
to be cleared or set. For older systems and all newer systems with the UEFI BIOS platform, customers can download the Dell
