The Intel Macs didn't originally ship with any form of BIOS, and the newer ones only have a BIOS compatibility module in the EFI system. The only reason they added the BIOS mod was so geeks could dual-boot OSX with more traditional x86 OSes.
The Intel version of OSX wont boot on anything but specialized EFI systems. People have done hacking to both OSX and EFI implementations to get OSX running on non-standard hardware. At least one fellow managed to get OSX to run mostly stable on a hacked Dell laptop. As far as I know, there are no working EFI implementations that aren't based on an Intel chip (Intel did make EFI after all), and so the system must be Intel based to run OSX, regardless of if its Mac hardware or not.
Not sure what exactly this has to do with the original post, but then again I have yet to determine what the goal of the original post was...

While I'm not sure of the particulars, I heard that it's only a few minor code adjustments to get the OS to run on Intel hardware. If I remember right, it's a BIOS checking thing. If it's not the Mac BIOS, it won't install or run?

For a long time, I've been under the impression, largely from friends who have been running Macintoshes for ages, that OS-X was based on one of the three BSD forks - that essentially it was a *BSD with an Apple window manager/desktop environment, and with the kernel (and other programs) locked to the Trusted Program Module (TPM).
Comments from some of you lately led me to do some research. It appears that, at least on the internet, current documentation agrees that OS-X is based on Openstep, which evolved from NeXTSTEP, which was derived from 4.4 BSD (pre-fork?) and the Mach OS.
It's funny how knowledge like this can evolve on the web. What gets collated, analyzed, and archived becomes the truth. What was known to be true at the time gets forgotten. Mode Emulators become Modulator/Demodulators. Other acronyms drift. _______________________________________________ Kclug mailing list [email protected] http://kclug.org/mailman/listinfo/kclug
