Mac OS X booting up in single-user mode. In PowerPC-based Macintoshes, the boot process starts with the activation of BootROM, the basic Macintosh ROM, which performs a Power On Self Test to test hardware essential to startup. [4] On the passing of this test, the startup chime is played and control of the computer is passed to OpenFirmware.

Once Toolbox is running, PPC machines can boot into Mac OS directly. On all Old World ROM machines, once Toolbox is loaded, the boot procedure is the same. Toolbox executes a memory test, enumerates Mac OS devices it knows about (this varies from model to model), and either starts the on-board video (if present) or the option ROM on a NuBus or ...
