UEFI is the acronym for Unified Extensible Firmware Interface. It is basically a replacement for BIOS which is used to laid the hardware together with charge together with start an operating organization inward today’s Windows 10/8 PCs.
What is UEFI
The ancestor of UEFI was developed past times Intel for their Itanium based servers. The principal limitation of BIOS was that it was a 16-bit amongst simply 1 MB of addressable infinite together with utilized Master Boot Record (MBR) sectionalization scheme. Thus at that topographic point were constraints on the total of RAM that could hold upwardly used past times BIOS, together with it couldn’t back upwardly an HDD amongst a capacity of to a higher house 2.2TB. In monastic enjoin to overcome these limitations, Intel introduced the Intel Boot Initiative which was afterward renamed equally EFI. It was together with thence taken over past times the Unified EFI Forum, which evolved it into UEFI.
The original EFI interface is used inward Macs together with exclusively supports Intel processors. But UEFI, on the other hand, supports both Intel together with AMD processors.
Advantages of UEFI
UEFI supports both 32-bit together with 64-bit architecture. Thus it tin forcefulness out utilize to a greater extent than RAM to produce to a greater extent than complex processes than BIOS. UEFI too back upwardly CPU independent architecture together with drivers.
Unlike BIOS, UEFI tin forcefulness out get got a to a greater extent than visually pleasing interface that supports a mouse. See the Asus UEFI interface below.
Apart from the measure MBR sectionalization scheme, UEFI too supports GUID Partition Table or GPT. GPT allows for a maximum disk together with sectionalization size of 9.4 ZB (compared to 2.2TB of MBR) together with 128 partitions on Windows (compared to four of MBR).
UEFI comes amongst a kick director which removes the needs for a split kick loader. UEFI too supports extensions such equally ACPI that are non 16-bit. Besides, UEFI too gives yous faster start-ups together with improve networking support.
With the advancement inward the hardware industry, BIOS is becoming to a greater extent than together with to a greater extent than insufficient to lead maintain the might together with capacities of today’s machines together with UEFI has the capability to lead maintain our ever-growing thirst for to a greater extent than computing might at to the lowest degree for the adjacent ii decades.
Read: Choose UEFI or Legacy BIOS when booting into Windows Setup or Windows PE.
In general, UEFI-enabled machines get got faster startup together with shutdown times equally compared to BIOS-based machines. Here is a listing of Windows 10 features that requires UEFI:
- Secure Boot protects Windows 10 pre-boot procedure against bootkit together with other malware attacks.
- Early Launch Anti-malware (ELAM) driver gets loaded past times Secure Boot root together with checks all non-Microsoft drivers earlier they are loaded.
- Windows Trusted Boot protects the essence together with organization drivers during launch.
- Measured Boot volition stair out components from firmware till the kick start drivers & stores these measurements inward the TPM chip.
- Device Guard uses CPU virtualization together with TPM back upwardly to back upwardly Device Guard amongst AppLocker, together with Device Guard amongst Credential Guard.
- Credential Guard plant amongst Device Guard together with uses CPU virtualization together with TPM back upwardly to protect safety data similar NTLM hashes, etc.
- BitLocker Network Unlock volition automatically unlock Windows 10 at reboot when connected to a corporate network.
- GUID Partition Table or GPT disk partitioning is required to enable large kick disks.
Hopefully, to a greater extent than manufacturers volition switch to UEFI from BIOS.
