The Null Device
Apparently another casualty of Apple's move to Intel is OpenFirmware
; the standardised, portable, FORTH-based firmware used on PowerPC Macs has been replaced by Intel's proprietary, architecture-specific EFI (originally designed for the next generation of Windows machines). Which further locks Apple into one vendor (unless, of course, they further redesign their platform), and relegates OpenFirmware to the graveyard of cool technologies, alongside the likes of NeWS, Open Look, and numerous non-PC architectures.
And it's increasingly looking like the main architectural difference between the new Intel-based Macs and, say, Dells or Sony Vaios, could be the key in the DRM chip which authenticates it as an Apple, allowing MacOS X to run on it.
