Linux dual-booting is achieved by partitioning the boot drive, installing the Yaboot bootloader onto the Linux partition, and selecting that Linux partition as the Startup Disk. This results in users being prompted to select whether they want to boot into Mac OS or Linux when the machine starts.
For a cold boot, for example, it may need to execute all of its functionality. If, however, the system supports power saving or quick boot methods, the BIOS may be able to circumvent the standard POST device discovery, and simply program the devices from a preloaded system device table.
On iPhone, iPad, Apple Watch, iPod Touch, and Apple TV devices, the boot ROM is called "SecureROM" [8] It is a stripped-down version of iBoot. It provides a Device Firmware Upgrade (DFU) mechanism, which can be activated using a special button combination.
Bootloader unlocking is the process of disabling the bootloader security that enforces secure boot during the boot procedure. It can allow advanced customizations possible, such as installing custom firmware. On smartphones, this can be a custom Android distribution or another mobile operating system. Some bootloaders are not locked at all and ...
Settings is an app available since initial launch of the original iPhone in 2007. Settings allows users to access information about their device and change the settings and options on their phone such as the device wallpaper, notifications, Wi-Fi and Bluetooth , display and brightness, Siri and more.
When debugging a concurrent and distributed system of systems, a bootloop (also written boot loop or boot-loop) is a diagnostic condition of an erroneous state that occurs on computing devices; when those devices repeatedly fail to complete the booting process and restart before a boot sequence is finished, a restart might prevent a user from ...
iOS jailbreaking is the use of a privilege escalation exploit to remove software restrictions imposed by Apple on devices running iOS and iOS-based [a] operating systems. It is typically done through a series of kernel patches.
All Apple silicon-based Macs use a newer method separate from previous Macs where it uses a boot ROM located on the SoC to launch iBoot, in a similar manner to that of the iPhone and iPad. [ 2 ] An Apple PowerBook 180c displaying the Happy Mac during the startup process
