Hi, Intel Macs do not have Open Firmware. That was a mistake on my part. EFI doesn't seem to have an interface, though I suppose that the Boot Manager is the only exception capable of directly accessing the EFI. The only thing EFI does have is Legacy BIOS support so that operating systems requiring a BIOS to load such as Microsoft Windows are capable of doing so. Hopefully, Apple will create a direct way of accessing the Extensible Firmware Interface at some point, but it doesn't look like it is possible right now. I'm sure it provides the same features and even more than the Open Firmware for the Power-based Macs, so that's very exciting if it can be directly accessed someday.
