Yeah, that makes sense for the bulk of the applications that make up the OS. Again, I am comfortable with the concept of Universal Applications in general.
But the computer geek inside me is wondering, though, exactly what mechanism is used to actually boot off the DVD when you first insert it in the drive? I mean, some Macs are running OpenFirmware on PPC CPUs, and others are running EFI on Intel CPUs.
How, with a single boot sector on most removable media, is the computer going to decide which code set (PPC or Intel) to load in those first few nanoseconds without the benefit of knowing what a Universal Binary is? (Or are OpenFirmware/EFI themselves already aware of the concept of fat binaries?)
I'm sure there's a reasonable answer out there, and it's driving me crazy that I can't think of it. I'm just hoping someone out there will be kind enough to educate me.
