UEFI is the successor to the BIOS and is mainly used on newer computers are used. But what are actually exactly the differences between UEFI and BIOS? Is this a better than the other, and how to call the BIOS or UEFI on? clarify these issues, we see the following article.

UEFI and BIOS &# 8211; What is that?

BIOS means Basic Input Output System, which means central input and output system in German. is meant a control unit which controls the individual components of the computer, e.g. the CPU manages and controls.

  • The main task of the BIOS to make the computer ready for operation.
  • At system startup, the BIOS initializes the individual components on the motherboard of the PC and then checks the functionality of the PC.
  • After that, it passes control of the PC to the device installed on the computer operating system.
  • In BIOS also system settings can be changed and on and off individual components and interfaces.
  • The two main manufacturer for BIOS is AMI and Award / Phoenix, each providing their own versions of the Basic Input Output System.

UEFI stands for Unified Extensible Firmware Interface (In German about: Unified Extensible Firmware Interface) and is the successor of the conventional BIOS. The basic tasks of UEFI are basically the same as the BIOS, but in addition, it provides some additional features (more on that below).

  • UEFI was launched at the initiative of Intel, AMD, Microsoft, Hewlett-Packard, and other hardware manufacturers.
  • The goal was to develop a simple-to-use interface that takes advantage of the graphical capabilities of modern hardware better than conventional BIOS.
  • On Windows computers UEFI comes exclusively on 64-bit operating system used.
  • In addition, UEFI is also compatible with Linux.
  • On Mac computers UEFI is used since the introduction of OS X.

BIOS and UEFI &# 8211; The main differences

The old BIOS was developed in the 1970s and was first used in 1981 on the very first IBM PC used. Accordingly, old-fashioned BIOS works nowadays &# 8211; you can see clearly that the BIOS dates back to the MS-DOS era and no longer entirely on the amount of time. The successor UEFI has compared a simpler user interface and additional features that are now standard. These are the main differences:

  • The BIOS is limited to VGA image size of 640 x 480 pixels &# 8211; Instead UEFI BIOS uses much higher resolutions and color depths, which contributes to a better clarity.
  • In addition, UEFI can be operated by mouse &# 8211; the BIOS you are limited to typing with the keyboard.
  • Unlike the BIOS UEFI contains all the drivers that Windows needs to boot the system. Therefore, the boot process when UEFI runs significantly faster than with BIOS.
  • UEFI also has a standard driver for the network card. So you can use the network connection before the start of the operating system, for example, to download firmware updates and install.
  • Updates can be loaded directly and install UEFI &# 8211; the BIOS you have the update first download to your computer and then flash the BIOS.
  • Hard disks are partitioned differently with UEFI: Instead of only 4 primary partitions (BIOS) you can with UEFI create up to 128 partitions.
  • In addition, can be processed (BIOS: 2.2 TB) with UEFI up to 3 terabytes large storage media.
  • may contain Some providers UEFI also games, a RAM test or browser. So you can surf completely without an operating system on the Internet.

The process, enter the BIOS or UEFI differs depending on the manufacturer and operating system. The BIOS can be reached in most cases with the Delete key &# 8211; but sometimes you have to press another button. The following items show you how to reach her in the BIOS or UEFI:

  • Windows 10: Start bios and change settings - Here's
  • Windows 8 BIOS (UEFI): So you come into the firmware setup
  • How do I get into the BIOS - Windows XP, Vista, 7
  • call BIOS - how it works!
