Unified Extensible Firmware Interface Wikipedia. EFIs position in the software stack. The Unified Extensible Firmware Interface UEFI is a specification that defines a software interface between an operating system and platform firmware. UEFI replaces the Basic InputOutput System BIOS firmware interface originally present in all IBM PC compatiblepersonal computers,12 with most UEFI firmware implementations providing legacy support for BIOS services. UEFI can support remote diagnostics and repair of computers, even with no operating system installed. The user can enter a setup utility by pressing their manufacturers specific setup keys. Most common keys are Delete,F2, F1. Intel developed the original Extensible Firmware Interface EFI specification. Some of the EFIs practices and data formats mirror those from Microsoft Windows. In 2. UEFI deprecated EFI 1. EFI. The Unified EFI Forum is the industry body that manages the UEFI specification. HistoryeditThe original motivation for EFI came during early development of the first IntelHP Itanium systems in the mid 1. BIOS limitations such as 1. MB addressable space and PC AT hardware had become too restrictive for the larger server platforms Itanium was targeting. The effort to address these concerns began in 1. Intel Boot Initiative. It was later renamed to Extensible Firmware Interface EFI. In July 2. Intel ceased its development of the EFI specification at version 1. Name synopsis description api overview. Linux System Administration and Configuration After installation, Linux requires configuration and systems administration. Corporate systems need monitoring, backups. Ubuntu b n t u stylized as ubuntu is an open source operating system for computers. It is a Linux distribution based on the Debian architecture. Notes Obviously, you know this site is not the Chromium official website. As a regular user not an expert, I created it because I did not find a simple way to. Unified EFI Forum, which has developed the specification as the Unified Extensible Firmware Interface UEFI. The original EFI specification remains owned by Intel, which exclusively provides licenses for EFI based products, but the UEFI specification is owned by the Forum. Version 2. 1 of the UEFI specification was released on 7 January 2. It added cryptography, network authentication and the User Interface Architecture Human Interface Infrastructure in UEFI. The latest UEFI specification, version 2. May 2. 01. 7. 1. 1AdvantageseditThe interface defined by the EFI specification includes data tables that contain platform information, and boot and runtime services that are available to the OS loader and OS.

Standard PC BIOS is limited to a 1. MB of addressable memory space, resulting from the design based on the IBM 5. Intel 8. 08. 8 processor. In comparison, the processor mode in a UEFI environment can be either 3. AArch. 32 or 6. 4 bit x. Itanium, and AArch. NXDesignForum/16889/1/Capture.PNG' alt='Installer User Interface Mode Not Supported Ubuntu' title='Installer User Interface Mode Not Supported Ubuntu' />UEFI firmware implementations support long mode, which allows applications in the preboot execution environment to use 6. UEFI requires the firmware and operating system loader or kernel to be size matched for example, a 6. UEFI firmware implementation can load only a 6. OS boot loader or kernel. After the system transitions from Boot Services to Runtime Services, the operating system kernel takes over. At this point, the kernel can change processor modes if it desires, but this bars usage of the runtime services unless the kernel switches back again. As of version 3. 1. Linux kernel supports 6. UEFI firmware implementations running on x. CPUs, with UEFI handover support from a UEFI boot loader as the requirement. Installer User Interface Mode Not Supported Ubuntu' title='Installer User Interface Mode Not Supported Ubuntu' />UEFI handover protocol deduplicates the UEFI initialization code between the kernel and UEFI boot loaders, leaving the initialization to be performed only by the Linux kernels UEFI boot stub. Disk device compatibilityeditIn addition to the standard PC disk partition scheme that uses a master boot record MBR, UEFI also works with a new partitioning scheme called GUID Partition Table GPT, which is free from many of the limitations of MBR. In particular, the MBR limits on the number and size of disk partitions up to four primary partitions per disk, and up to 2 Ti. B2 2. 40bytes per disk are relaxed. More specifically, GPT allows for a maximum disk and partition size of 8 Zi. B8 2. 70 bytes. 2. Support for GPT in Linux is enabled by turning on the option CONFIGEFIPARTITION EFI GUID Partition Support during kernel configuration. This option allows Linux to recognize and use GPT disks after the system firmware passes control over the system to Linux. For reverse compatibility, Linux can use GPT disks in BIOS based systems for both data storage and booting, as both GRUB 2 and Linux are GPT aware. Such a setup is usually referred to as BIOS GPT. As GPT incorporates the protective MBR, a BIOS based computer can boot from a GPT disk using a GPT aware boot loader stored in the protective MBRs bootstrap code area. In the case of GRUB, such a configuration requires a BIOS boot partition for GRUB to embed its second stage code due to absence of the post MBR gap in GPT partitioned disks which is taken over by the GPTs Primary Header and Primary Partition Table. Commonly 1 Mi. B in size, this partitions Globally Unique Identifier GUID in GPT scheme is 2. E6. F 7. 44. E 6. GRUB only in BIOS GPT setups. From GRUBs perspective, no such partition type exists in case of MBR partitioning. This partition is not required if the system is UEFI based because no embedding of the second stage code is needed in that case. UEFI systems can access GPT disks and boot directly from them, which allows Linux to use UEFI boot methods. Booting Linux from GPT disks on UEFI systems involves creation of an EFI system partition ESP, which contains UEFI applications such as bootloaders, operating system kernels, and utility software. Millennium 3 Cry Wolf'>Millennium 3 Cry Wolf. Of Microsoft Frontpage 2003 Full Version. Such a setup is usually referred to as UEFI GPT, while ESP is recommended to be at least 5. Mi. B in size and formatted with a FAT3. For backward compatibility, most UEFI implementations also support booting from MBR partitioned disks, through the Compatibility Support Module CSM that provides legacy BIOS compatibility. In that case, booting Linux on UEFI systems is the same as on legacy BIOS based systems. Microsoft WindowseditThe 6. Windows 7 and later can boot from disks with a partition size larger than 2 TB. FeatureseditServiceseditEFI defines two types of services boot services and runtime services. Boot services are available only while the firmware owns the platform i. Exit. Boot. Services call, and they include text and graphical consoles on various devices, and bus, block and file services. Runtime services are still accessible while the operating system is running they include services such as date, time and NVRAM access. In addition, the Graphics Output Protocol GOP provides limited runtime services support see also Graphics features section below. The operating system is permitted to directly write to the framebuffer provided by GOP during runtime mode.
