UEFI Introduction

Update: 10/08/2010

UEFI (Unified Extensible Firmware Interface) BIOS is nextgeneration BIOS firmware based on UEFI specifications and the Intel® Platform Innovation Framework for EFI.

UEFI BIOS can be expanded by using a variety of drivers, development tools, support utilities and pre-boot application (PBA) solutions.

The architecture represents a structured implementation composed primarily of the following:
• Foundation code that binds the pieces together
• Modular elements of code that perform the functional job of enumerating and initializing the platform

UEFI Benefits

Expansibility –
ODM/OEM and customers can add their own PBA easily. PBA can be integrated in BIOS flash or placed in external mass storage devices.

Migration ability –
Drivers, PBA can be migrated easily from one platform to another because they’re designed highly modularize on a unified framework.
