The Basic Input/Output System (BIOS) served as the OS-firmware interface for the original PC-XT and PC-AT computers. BIOS has however not been completely modernized even with the advancement of the PC market and technology. The Unified EFI (UEFI) specification (previously known as the EFI specification) defines a similar interface between an operating system and platform firmware. UEFI is independent of the processor architecture and it defines a similar OS-firmware interface, known as "boot services" and "runtime services".
As per Mark Doran, head of the UEFI Forum ,UEFI is expected to predominate in new PCs by 2011.
UEFI is free from architectures limitation, as the technology scales across platforms (server, desktops, mobiles, handhelds).
For the users' perspective, the advantages of UEFI machines include fast boots (less than 5 seconds) as well and resume response. They could feature a high-resolution Graphics User Interface in pre-boot environment and the systems will be able to boot from large (2.2TB or higher) disks. In addition, Users may also be able to access Outlook data in seconds even when their notebook is off.
