- Apple-Intel architecture
The Apple-Intel architecture is an unofficial name used for
Apple Macintosh personal computer s developed and manufactured byApple Computer that useIntel x86 processors, rather than thePowerPC and68k processors used in their predecessors.Technologies
Apple uses a subset of the standard PC architecture, which provides support for Mac OS X and limited support for other operating systems. Hardware and firmware components that must be supported to run an operating system on Apple-Intel hardware are listed below.
Extensible Firmware Interface
Extensible Firmware Interface (EFI) is the firmware-based replacement for the PC
BIOS from Intel. Designed by Intel, it was chosen by Apple to replaceOpen Firmware , used onPowerPC architectures. Since many operating systems, such as Windows XP and many versions of Windows Vista are incompatible with EFI, Apple has released a firmware upgrade with a compatibility support module that provides a subset of traditional BIOS support with their Boot Camp product.GUID Partition Table
GUID Partition Table (GPT) is a standard for the layout of the partition table on a physical hard disk. It is a part of the Extensible Firmware Interface (EFI) standard proposed by Intel as a substitute for the more common PC BIOS. The GPT replaces the Master Boot Record (MBR) used with BIOS.
