The Mac and BIOS

It seems that there is a lot of nonsense on the Internet regarding this subject. At the end of the day it makes no odds whether the system or method that Apple use to determine the way that Mac computers boot is a System BIOS or a EFI.

It could be stated that the reason that Macs can be used with an operating system other than OSX is that Apple had moved to Intel microprocessors and an EFI but it can also be stated that pc manufacturers have also moved to an EFI framework for the BIOS used in non-Mac computers.

To this end it remains that this is largely semantics and it really makes no difference to the efforts of those that want to run an alternate operating system on ether of the two hardware platforms.
The quest to run OSX on non-Apple hardware continues and the endless thread of questions from those that are having problems in getting Boot Camp to run Windows on their Macs continues.

Whether Boot Camp Assistant is a just a partition tool and not much else, whether there are better tools and why some seem to continue to have problems in getting it to work are all continuing in 2011.
The installation of a Hackintosh or the booting of OSX on ANY hardware revolves around the requirement for a bootable media for the operating system used for the initial setup is the issue at hand NOT the settings of the hardware (EFI/BIOS) - setting the SATA Type to AHCI for example.
Even the Lifehacker instructions detail the preparation of a thumb drive to boot the hardware into OSX and then subsequently install OSX onto the computers hard drive. The converse of this is Boot Camp where a Windows (or other OS) partition is created on the Mac computer and then there is an option to install that alternate operating system. In the second case, Boot Camp, the process that installs Windows (for example) is the Windows installer NOT anything supplied by Boot Camp.

In both cases, the installation of a Hackintosh on Windows hardware and the installation of Windows on Apple hardware, there may be changes made to the EFI settings but these are largely hidden from the user.

The final analysis of all of this is that you are better off buying a Mac if you want to run OSX - but then I have a different assessment of the time value of money.

I was wondering what the fundamental differences were between a Macintosh and a Windows PC with respect to their pre-boot environments.

What are the settings that need to be set so that you can install OSX on a computer that has a conventional BIOS or EFI
