UEFI full called Unified Extensible Firmware Interface (Unified Extensible Firmware Interface), is better than traditional Bios, even EFI (Extensible Firmware Interface) more advantage of new technology products.

The new UEFI, the full name "Unified Extensible fixed Interface" (Unified Extensible Firmware Interface), is a detailed description of new type Interface standard. This kind of interface for operating the toshiba satellite a85 series laptop cpu cooling fan system automatically from pre start operating environment, loading into a kind of operating system, so that the boot programmed numerous for Jane, save time. As a computer boot software Bios now for more than 25 years of history, and a recent technology upgrade may make the "grand old man level" computer element from now on exit historical stage.

The difference between UEFI and BIOS

UEFI is by EFI1.10 as the foundation of the development of, its owners are no longer Intel toshiba satellite a85 s107 laptop cpu cooling fan, but a called Unified EFI Form international organization, the contributors to have Intel, Microsoft, AMI, and several other companies, belongs to the open source, current version 2.1. Compared with legacy BIOS, the biggest difference is that a few:

1. 99% coding by C language finish,
2. Change before the interrupt, hardware port operation method, and use the Driver/protocol new way;
3. Will not support X86 real mode, and direct the Flat mode (that is, can't use DOS, now some EFI or UEFI can do because the compatible, but in fact this section does not belong to the definition of UEFI);
4. Output also is no longer simple Binary code, instead of a Removable Binary Drivers;
5. OS start is no longer call Int19, but direct use toshiba satellite a85 s1072 laptop cpu cooling fan protocol/device Path;
6. For the development of the third party, the former basically do not, unless in the design of the BIOS, but but also by the size of the ROM restriction, and the latter is much more convenient.
7. Make up for the new BIOS hardware support shortage problem.
UEFI will be nearly 3 years of trend, when the time comes for PC use and maintenance will be moving into a new era.

Windows 8 and traditional BIOS say bye bye, will be UEFI give priority to

In the far distant past, Windows and GUI haven't become you to "computer" operation standard before the impression, the computer operation are mostly depend on the keyboard to the instruction (of course use Linux friend will probably say now or...) . Today, most of the computer toshiba satellite c630 series laptop cpu cooling fan operation are Windows Logo out later, but occasionally boot process problems, or have the opportunity to see the plain text keyboard, must want to keyboard operation menu screen. But as the Windows and arrival, no keyboard, can only use touch operation of the tablet PC become the new operating system must take account of a piece of, plus the popularity of UEFI recently, so Windows and decided to UEFI is given priority to, but still keep the traditional BIOS support.
