GRUB 2, elilo and systemd-boot serve as conventional, full-fledged standalone UEFI boot managers (a.k.a. bootloader managers) for Linux. Once loaded by a UEFI firmware, they can access and boot kernel images from all devices, partitions and file systems they support, without being limited to the EFI system partition.
The BIOS boot partition is a partition on a data storage device that GNU GRUB uses on legacy BIOS-based personal computers in order to boot an operating system, when the actual boot device contains a GUID Partition Table (GPT). Such a layout is sometimes referred to as BIOS/GPT boot.
fwupd is an open-source daemon for managing the installation of firmware updates on Linux-based systems, developed by GNOME maintainer Richard Hughes. [1] It is designed primarily for servicing the Unified Extensible Firmware Interface (UEFI) firmware on supported devices via EFI System Resource Table (ESRT) and UEFI Capsule, which is supported in Linux kernel 4.2 and later.
ISOLINUX is generally used by Linux live CDs and bootable install CDs. rEFInd, a boot manager for UEFI systems. coreboot is a free implementation of the UEFI or BIOS and usually deployed with the system board, and field upgrades provided by the vendor if need be. Parts of coreboot becomes the systems BIOS and stays resident in memory after boot.
UEFI machines can have one of the following classes, which were used to help ease the transition to UEFI: [96] Class 0: Legacy BIOS; Class 1: UEFI with a CSM interface and no external UEFI interface. The only UEFI interfaces are internal to the firmware. Class 2: UEFI with CSM and external UEFI interfaces, eg. UEFI Boot.
In this scenario, the operating system is stored on the disk of a server, and certain parts of it are transferred to the client using a simple protocol such as the Trivial File Transfer Protocol (TFTP). After these parts have been transferred, the operating system takes over the control of the booting process.
In computing, the System Management BIOS (SMBIOS) specification defines data structures (and access methods) that can be used to read management information produced by the BIOS of a computer. [1] This eliminates the need for the operating system to probe hardware directly to discover what devices are present in the computer.
This is a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems. GNU Core Utilities include basic file, shell and text manipulation utilities. Coreutils includes all of the basic command-line tools that are expected in a POSIX system.
