Apple-intel Architecture




The Apple-Intel architecture is a name used for Apple Macintosh Personal Computer s developed and manufactured by Apple Computer which use Intel X86 processors, rather than the PowerPC and 68k processors used in their predecessors.


RUNNING OPERATING SYSTEMS OTHER THAN MAC OS X


On , "Leopard".

Both Windows XP on Intel Macs are currently able to boot on the new Intel Macintoshes.

Prior to Boot Camp, which provides most hardware drivers for Windows XP, drivers for XP were very difficult to find.

Being able to dual boot between the two most popular Operating System s has the following benefits:
  • Being able to choose the user's preferred system and its interface.

  • Being able to use more software (in particular, more games) by being able to run programs designed only for Windows, which would likely be faster than Emulation or a Compatibility Layer .

  • Being able to use software that is designed only for, works faster on, or is more intuitive on Mac OS X (for example, Adobe Photoshop ).

  • Being able to make transitions between operating systems easier by using the same familiar hardware.

  • Being able to use an Apple-Intel computer to provide support for both systems using the same hardware.

  • Being able to test applications across different operating systems without having to invest in twice as much hardware, or to test files/documents between different platform-specific software suites (for example, to test a web document between Internet Explorer 6 and Safari 2.0 ).


New hardware and firmware components that must be supported to run an operating system on Apple-Intel hardware are:


EFI

Extensible Firmware Interface (EFI) is the firmware-based replacement for the PC BIOS from Intel. Designed by Intel, it has been chosen by Apple to replace OpenFirmware , used on PowerPC architectures.


GPT

See Also: GUID Partition Table




TPM

See Also: Trusted Platform Module




VIRTUAL PC

Microsoft has stated that its Macintosh Business Unit will port Virtual PC to the Intel Mac platform Can Developers Give Mactel an Enterprise Boost? -eWeek . An Intel version of Virtual PC for Mac will hold out the possibility of running Windows with almost native performance on a Mac, with the ability to access graphics hardware while being able to run both OS's at once and switch between operating systems on the fly, rather than having to dual-boot and run only one operating system at a time.
