Bootloader unlocking is the process of disabling the bootloader security that makes secure boot possible. It can make advanced customizations possible, such as installing a custom firmware. On smartphones this can be a custom Android distribution or another mobile operating system. Some bootloaders are not locked at all, others can be unlocked ...
Bootloader. GNU GRUB, a popular open source bootloader. Windows bootloader. A bootloader, also spelled as boot loader[1][2] or called bootstrap loader, is a computer program that is responsible for booting a computer. If it also provides an interactive menu with multiple boot choices then it's often called a boot manager.
Fastboot is a communication protocol used primarily with Android devices. [1] It is implemented in a command-line interface tool of the same name and as a mode of the bootloader of Android devices. The tool is included with the Android SDK package and used primarily to modify the flash filesystem via a USB connection from a host computer.
Target Disk Mode. Target Disk Mode (sometimes referred to as TDM or Target Mode) is a boot mode unique to Macintosh computers. When a Mac that supports Target Disk Mode [1] is started with the 'T' key held down, its operating system does not boot. Instead, the Mac's firmware enables its drives to behave as a SCSI, FireWire, Thunderbolt, or USB ...
Booting process of Android devices. The booting process of Android devices starts at the power-on of the SoC (system on a chip) and ends at the visibility of the home screen, or special modes like recovery and fastboot. [a] The boot process of devices that run Android is influenced by the firmware design of the SoC manufacturers.
They can use different I/O protocols, but SPI is the most common. Unified Extensible Firmware Interface (UEFI, / ˈjuːɪfaɪ / or as an acronym) [c] is a specification that defines an architecture for the platform firmware used for booting a computer's hardware and its interface for interaction with the operating system.
iBoot. iBoot is the stage 2 bootloader for all Apple products. [3] It replaces the old bootloader, BootX. Compared with its predecessor, iBoot improves authentication performed in the boot chain. [2] For x86 -based Macs, the boot process starts by running code stored in secured UEFI Boot ROM (stage 1).
If an expansion ROM wishes to change the way the system boots (such as from a network device or a SCSI adapter) in a cooperative way, it can use the BIOS Boot Specification (BBS) API to register its ability to do so. Once the expansion ROMs have registered using the BBS APIs, the user can select among the available boot options from within the ...
