Like Apple_Boot but on Old World Macs, it is used when Mac OS X is installed on a file system not readable by Open Firmware. This partition does not contain a filesystem—instead it contains the BootX machine code in XCOFF format. This partition type was discontinued with Mac OS X 10.3. Apple_MDFW: firmware: firmware
On Apple Mac computers using Intel x86-64 processor architecture, the EFI system partition is initially left blank and unused for booting into macOS. [13] [14]However, the EFI system partition is used as a staging area for firmware updates [15] and for the Microsoft Windows bootloader for Mac computers configured to boot into a Windows partition using Boot Camp.
Secure deletion of free space or disk using a "zero out" data, a 7-pass DOD 5220-22 M standard, or a 35-pass Gutmann algorithm; Adding or changing partition table between Apple Partition Map, GUID Partition Table, and master boot record (MBR) Restoring volumes from Apple Software Restore (ASR) images; Checking the S.M.A.R.T. status of a hard disk
A modern PC is configured to attempt to boot from various devices in a certain order. If a computer is not booting from the device desired, such as the floppy drive, the user may have to enter the BIOS Setup function by pressing a special key when the computer is first turned on (such as Delete, F1, F2, F10 or F12), and then changing the boot order.

Boot Camp 4.0 for Mac OS X 10.6 Snow Leopard version 10.6.6 up to Mac OS X 10.8 Mountain Lion version 10.8.2 only supported Windows 7. [3] However, with the release of Boot Camp 5.0 for Mac OS X 10.8 Mountain Lion in version 10.8.3, only 64-bit versions of Windows 7 and Windows 8 are officially supported. [4] [5]
Darik's Boot and Nuke, also known as DBAN / ˈ d iː b æ n /, is a free and open-source project hosted on SourceForge. [2] The program is designed to securely erase a hard disk until its data is permanently removed and no longer recoverable, which is achieved by overwriting the data with pseudorandom numbers generated by Mersenne Twister or ISAAC.
A Sad Mac is a symbol in older-generation Apple Macintosh computers (hardware using the Old World ROM and not Open Firmware, which are those predating onboard USB), starting with the original 128K Macintosh and ending with the last NuBus-based Power Macintosh models (including the first-generation 6100, 7100, 8100, as well as the PowerBook 5300 ...
A block, a contiguous number of bytes, is the minimum unit of storage that is read from and written to a disk by a disk driver.The earliest disk drives had fixed block sizes (e.g. the IBM 350 disk storage unit (of the late 1950s) block size was 100 six-bit characters) but starting with the 1301 [8] IBM marketed subsystems that featured variable block sizes: a particular track could have blocks ...
