Bootloaders
A bootloader, also spelled as boot loader or called boot manager and bootstrap loader, is a computer program that is responsible for booting a computer. 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 read-only memory (ROM, and later EEPROM, Flash memory#NOR flash, NOR flash) along with some needed data, to initialize RAM (especially on x86 systems), to access the nonvolatile device (usually Device file#Block devices, block device, eg NAND flash) or devices from which the operating system programs and data can be loaded into RAM. Some earlier computer systems, upon receiving a boot signal from a human operator or a peripheral device, may load a very small number of fixed instructions into memory at a speci ...

GNU GRUB
GNU GRUB (short for GNU GRand Unified Bootloader, commonly referred to as GRUB) is a boot loader package from the GNU Project. GRUB is the reference implementation of the Free Software Foundation's Multiboot Specification, which provides a user the choice to boot one of multiple operating systems installed on a computer or select a specific kernel configuration available on a particular operating system's partitions. GNU GRUB was developed from a package called the ''Grand Unified Bootloader'' (a play on Grand Unified Theory). It is predominantly used for Unix-like systems. The GNU operating system uses GNU GRUB as its boot loader, as do most Linux distributions and the Solaris operating system on x86 systems, starting with the Solaris 10 1/06 release. Operation Booting When a computer is turned on, its BIOS finds the primary bootable device (usually the computer's hard disk) and runs the initial bootstrap program from the master boot record (MBR). The MBR is the fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
REFIt
Refitting or refit of boats and marine vessels includes repairing, fixing, restoring, renewing, mending, and renovating an old vessel. Refitting has become one of the most important activities inside a shipyard. It offers a variety of services for an old vessel of any size and kind starting with the construction itself and what is added to it, such as hardware, electric & hydraulic systems, entertainment systems, etc. Ship refits can range from relatively straightforward small changes and new livery up to and including cutting the ship in half to facilitate near-total overhauls and redesign of interior spaces. Refitting can be divided into several main subjects: *''Adding'' or ''replacing'': for example replacing old deck equipment with new or refurbished ones. *''Modifying'': for example modifying a yacht for participating in winning a regatta. *''Customizing'': for example customizing a yacht for the owner's needs and desires. *''Modernizing'': for example modernizing an old y ...

RedBoot
RedBoot (an acronym for Red Hat Embedded Debug and Bootstrap firmware) is an open-source application that uses the eCos real-time operating system Hardware Abstraction Layer to provide bootstrap firmware for embedded systems. RedBoot allows download and execution of embedded applications via serial or Ethernet, including embedded Linux and eCos applications. It provides debug support in conjunction with GDB to allow development and debugging of embedded applications. It also provides an interactive command line interface to allow management of the Flash images, image download, RedBoot configuration, etc., accessible via serial or Ethernet. For unattended or automated startup, boot scripts can be stored in Flash allowing, for example, loading of images from Flash, hard disk, or a TFTP server.

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 i ... [...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] |
LILO (boot Loader)
LILO (Linux Loader) is a boot loader for Linux and was the default boot loader for most Linux distributions in the years after the popularity of loadlin. Today, many distributions use GRUB as the default boot loader, but LILO and its variant ELILO are still in wide use. 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 made, but later also for standard i386 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 network booting using TFTP/DHCP. See also * /boot/ In Linux, and other Unix-like operating systems, the directory holds files used in booting the operating system. The usage is standardized in the Filesystem Hierarchy Standard.

IBoot (Bootloader)
iBoot is the stage 2 bootloader for all Apple products. It replaces the old bootloader, BootX. Compared with its predecessor, iBoot improves authentication performed in the boot chain. For x86 macOS, the boot process starts by running code stored in secured UEFI Boot ROM (first stage). Boot ROM has two primary responsibilities: to initialize system hardware and to select an operating system to run (the POST and UEFI component). For ARM macOS, the Boot ROM is not UEFI component. For iOS, the boot process starts by running the device's Boot ROM code. In systems with S1 processors or A9 or earlier A-series processors, the Boot ROM loads the Low-Level Bootloader (LLB), which loads iBoot. In systems with newer processors, the Boot ROM loads iBoot itself. If all goes well, iBoot will then proceed to load the iOS kernel as well as the rest of the operating system. If the LLB or iBoot fails to load iOS, or fails to verify iOS, the bootloader jumps to DFU (Device Firmware Update) mode; ...

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 ...
