Exempel på hur man kan använda UEFI i en mening

• The Portable Executable (PE) format is a file format for executables, object code, DLLs and others used in 32-bit and 64-bit versions of Windows operating systems, and in UEFI environments.
• Device drivers and firmware, including computer BIOS or UEFI, provide basic functionality to operate and control the hardware connected to or built into the computer.
• New features in Kanotix-Dragonfire are: booting from/with DVD, USB, UEFI (PCs, Intel Macs), an embedded USB-Stick ImageWriter for Mac OS X and the USB-Stick with Hybrid-ISO can now be made persistent from the live-system.
• Many different operating systems have been run on various simulated virtual platforms, including Linux, MS-DOS, Windows, VxWorks, OSE, Solaris, FreeBSD, QNX, RTEMS, UEFI, and Zephyr.
• Sometimes, booting from the destination drive can fail and require adjustments in the computer's UEFI or BIOS to make the new clone bootable.
• 0 (3 December 2013) was rewritten for UEFI booting (initially with fallback to BIOS booting on non-UEFI systems), allowing for secure boot approval and mouse support.
• With the release of Windows 8, Microsoft began requiring OEM devices to ship with UEFI system firmware, configured by default to only allow the execution of operating system binaries digitally signed by Microsoft (UEFI secure boot).
• UEFI replaces the BIOS which was present in the boot ROM of all personal computers that are IBM PC compatible, although it can provide backwards compatibility with the BIOS using CSM booting.
• In the early 2010s, the disk size limitations imposed by MBR became problematic and the GUID Partition Table (GPT) was designed as a replacement; modern computers using UEFI firmware without MBR support no longer use any notions from CHS addressing.
• In IBM PC compatible computers, the main duties of POST are handled by the BIOS or UEFI, which may hand some of these duties to other programs designed to initialize very specific peripheral devices, notably for video and SCSI initialization.
• Internally, ACPI advertises the available components and their functions to the operating system kernel using instruction lists ("methods") provided through the system firmware (UEFI or BIOS), which the kernel parses.
• Forming a part of the Unified Extensible Firmware Interface (UEFI) standard (Unified EFI Forum-proposed replacement for the PC BIOS), it is nevertheless also used for some BIOSs, because of the limitations of master boot record (MBR) partition tables, which use 32 bits for logical block addressing (LBA) of traditional 512-byte disk sectors.
• For example, the Unified Extensible Firmware Interface (UEFI) can use TPM to form a root of trust: The TPM contains several Platform Configuration Registers (PCRs) that allow secure storage and reporting of security-relevant metrics.
• In many systems on a chip, the peripherals or buses from which the boot ROM tries to load the bootloader (such as eMMC for embedded bootloader, or external EEPROM for UEFI implementation), and the order in which they are loaded, can be configured.
• At bootup when very little entropy is available, a special "initial seeding" procedure provides the seed from seed files, external entropy, TPM randomness, RDRAND/RDSEED instructions, ACPI-OEM0 table, UEFI entropy, and the current time.
• American Megatrends International, a main provider of UEFI firmware, embedded controller firmware, and baseboard management controller firmware.
• The IBM Integrated Management Module (IMM) is the next generation of System Management devices for UEFI based servers and comprises features and functionality of the legacy Baseboard Management Controller (BMC), Remote Supervisor Adapter II (RSA II) while incorporating the Super I/O controller and Video controller.
• In UEFI systems, the Linux kernel can be executed directly by UEFI firmware via the EFI boot stub, but usually uses GRUB 2 or systemd-boot as a bootloader.
• Internally, ACPI advertises the available components and their functions to the operating system kernel using instruction lists ("methods") provided through the system firmware (Unified Extensible Firmware Interface (UEFI) or BIOS), which the kernel parses.
• This module works in tandem with the BTX bootloader to support booting into BSD systems in both BIOS (MBR) and UEFI (GPT) environments, and the PC-BSD setup wizard has been developed with this capability and module of EasyBCD in mind.
