2.1.5 HII Database
The Human Interface Infrastructure Database is the resource that serves as the repository of all the IFR,
String, and Font data for the system. Drivers that contain information which is appropriate for the
database will export this data to the HII Database.
In a typical system, one might expect a driver which contains all the motherboard specific data
(traditional F1-setup for the system). Additionally, there might be other add-in cards that contain their
own drivers which have their own set of setup related data. All of the drivers that contain setup related
data would export their information to the HII Database.

2.1.6 Configuration Driver
The EFI Configuration Driver is the program that reads the contents of the HII Database and interprets
the data to present it to the user. This is also the program that takes the user input and provides for a
mechanism to save the changes into an NVRAM location.

2.2 Composition of VFR and String data
VFR has several keywords which determine the type of functions presented to the user. These
keywords reference strings via tokens, which make them language agnostic.
The strings are broken into language sections which have a one-to-one parallelism between each of the
strings. For instance, if string token #3 is the equivalent of “I love bananas” in the English section,
token #3 in any of the other language sections will contain strings that have the same meaning.
