Hi,
I am writing a cocoa application for our firweire device. I need to
know if the system is started up from firewire disk. For PowerPC with
Mac OSX 10.4/10.5, I have used information from "nvram boot-device".
For IntelMac with 10.4/10.5, I have used "nvram efi-boot-device". I am
not sure if it is a proper way, but it has been working OK. But on Mac
OS X 10.6, even if the systems is started from firewire disk, there is
no information in "nvram efi-boot-device" if it is connected to
firewire bus. Does anyone have an idea or know a proper way how to
determine if the system is started up from firewire disk.
Sincerely,
Ryota
