Bootloaders
A bootloader, also spelled as boot loader or called bootstrap loader, is a computer program that is responsible for booting a computer and booting an operating system. If it also provides an interactive menu with multiple boot choices then it's often called a boot manager. When a computer is turned off, its softwareincluding operating systems, application code, and dataremains stored on non-volatile memory. When the computer is powered on, it typically does not have an operating system or its loader in random-access memory (RAM). The computer first executes a relatively small program stored in the boot ROM, which is read-only memory (ROM, and later EEPROM, Flash memory#NOR flash, NOR flash) along with some needed data, to initialize hardware devices such as CPU, motherboard, memory, storage and other I/O devices, to access the nonvolatile device (usually Device file#Block devices, block device, e.g., NAND flash) or devices from which the operating system programs and data can be l ...

FreeBSD
FreeBSD is a free-software Unix-like operating system descended from the Berkeley Software Distribution (BSD). The first version was released in 1993 developed from 386BSD, one of the first fully functional and free Unix clones on affordable home-class hardware, and has since continuously been the most commonly used BSD-derived operating system. FreeBSD maintains a complete system, delivering a kernel, device drivers, userland utilities, and documentation, as opposed to Linux only delivering a kernel and drivers, and relying on third-parties such as GNU for system software. The FreeBSD source code is generally released under a permissive BSD license, as opposed to the copyleft GPL used by Linux. The project includes a security team overseeing all software shipped in the base distribution. Third-party applications may be installed using the pkg package management system or from source via FreeBSD Ports. The project is supported and promoted by the FreeBSD Foundation ...

NTLDR
NTLDR (abbreviation of ''NT loader'') is the boot loader for all releases of Windows NT operating system from 1993 with the release of Windows NT 3.1 up until Windows XP and Windows Server 2003. From Windows Vista onwards it was replaced by the BOOTMGR bootloader. NTLDR is typically run from the primary storage device, but it can also run from portable storage devices such as a CD-ROM, USB flash drive, or floppy disk. NTLDR can also load a non NT-based operating system given the appropriate boot sector in a file. NTLDR requires, at the minimum, the following two files to be on the system volume: * , the main boot loader itself * , required for booting an NT-based OS, detects basic hardware information needed for successful boot An additional important file is ''boot.ini'', which contains boot configuration (if missing, NTLDR will default to ''\Windows'' on the first partition of the first hard drive). NTLDR is launched by the volume boot record of system partition, which is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Loadlin
loadlin is a Linux boot loader that runs under 16-bit real-mode DOS (including the MS-DOS mode of Windows 95, Windows 98 and Windows Me startup disk). It allows the Linux system to load and replace the running DOS without altering existing DOS system files. loadlin and the Linux kernel are both files on a file system accessible to DOS. It loads the Linux kernel into memory from a file. It also places various configuration parameters into memory, and transfers control to the kernel. The kernel reads these parameters, initializes and runs, replacing DOS completely. Optionally, it can be configured to supply the kernel with an initial RAM disk, loaded into memory before transferring control to the Linux kernel. It passes to the kernel information about the RAM disk and its location. Furthermore, parameters can be passed to the Linux kernel that make it use that RAM disk as its root file system. The startup programs in that file system often cause Linux to mount another file sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Limine (bootloader)
Limine is a portable boot loader and the reference implementation for the Limine boot protocol. Multiboot2, chainloading, and the Linux boot protocols are also supported. Limine supports the ISO-9660 and FAT filesystems. Limine aims to provide a more robust alternative to bootloaders like GNU GRUB, as well as its own boot protocol as an alternative to the Multiboot specification, with the goal of reducing the amount of work needed for a kernel developer to get a workable 64-bit environment once booted. Limine is packaged by several Linux distributions, being offered by Arch Linux, where it is an option in archinstall, as well as included in EasyOS (a derivative of Puppy Linux), CachyOS, and Chimera Linux. Limine is also used by Cosmos and supported by SerenityOS.

LILO (boot Loader)
LILO (Linux Loader) is a bootloader for Linux and was the default boot loader for most Linux distributions . Unlike loadlin, it allowed booting Linux without having DOS on the computer. As of 2009, most distributions have switched to GRUB as the default boot loader. Further development of LILO was discontinued in December 2015 along with a request by Joachim Wiedorn for potential developers. ELILO For EFI-based PC hardware the now orphaned ELILO boot loader was developed, originally by Hewlett-Packard for IA-64 systems, but later also for standard i386 The Intel 386, originally released as the 80386 and later renamed i386, is the third-generation x86 architecture microprocessor from Intel. It was the first 32-bit processor in the line, making it a significant evolution in the x86 archite ... and amd64 hardware with EFI support. On any version of Linux running on Intel-based Apple Macintosh hardware, ELILO is one of the available bootloaders. It supports ne ...

IBoot (Bootloader)
iBoot is the stage 2 bootloader for iPhones, iPads, Apple silicon-based Macs, and the T2 chip in Intel-based Macs with such a chip. Compared with its predecessor, iBoot improves authentication performed in the boot chain. For Intel-based Macs with a T2 chip, the boot process starts by running code on the T2 chip from the boot ROM. That boot ROM loads and runs iBoot onto the T2 chip; iBoot loads the bridgeOS operating system onto the T2 chip and starts it; bridgeOS loads the UEFI firmware; UEFI firmware starts the main Intel processor and completes the Power-On Self Test process. The UEFI firmware loads boot.efi, which loads and starts the macOS kernel. For iPhones, iPads and Apple silicon-based Macs, the boot process starts by running the device's boot ROM. On iPhones and iPads with A9 or earlier A-series processors, the boot ROM loads the (LLB), which is the stage 1 bootloader and loads iBoot; on Macs and devices with A10 or later processors, the boot ROM loads iBoot.

GNU Lesser General Public License
The GNU Lesser General Public License (LGPL) is a free-software license published by the Free Software Foundation (FSF). The license allows developers and companies to use and integrate a software component released under the LGPL into their own (even proprietary) software without being required by the terms of a strong copyleft license to release the source code of their own components. However, any developer who modifies an LGPL-covered component is required to make their modified version available under the same LGPL license. For proprietary software, code under the LGPL is usually used in the form of a shared library, so that there is a clear separation between the proprietary and LGPL components. The LGPL is primarily used for software libraries, although it is also used by some stand-alone applications. The LGPL was developed as a compromise between the strong copyleft of the GNU General Public License (GPL) and more permissive licenses such as the BSD licenses and the MI ...

Gummiboot (software)
systemd-boot is a free and open-source boot manager, previously known as gummiboot. gummiboot gummiboot was developed by the Red Hat employees Kay Sievers and Harald Hoyer and designed as a minimal alternative to GNU GRUB for systems using the Unified Extensible Firmware Interface (UEFI). The boot loader automatically detected bootable images (including operating systems and other boot loaders), did not require a configuration file, provided a basic menu-based interface, and could also integrate with systemd to provide performance data. As a word play, the name "gummiboot" means " rubber (inflatable) boat" in German, the native language of its initial developers. Despite being developed by two of its employees, Red Hat's Fedora Project did not use gummiboot for booting UEFI systems; instead, it used efilinux to chainload GRUB. gummiboot was licensed under LGPL-2.1-or-later, unlike GRUB which is licensed under the GPL-3.0-or-later. This distinction was intended to allow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
