Process
A disk image with a copy of Mac OS X, Mac OS X Server, Mac OS 9, or Mac OS 8 is created using System Image Utility and is stored on a server, typically Mac OS X Server. Clients receive this image across a network using many popular protocols including but not limited to: HTTPS, AFP, TFTP, NFS, and multicast Apple Software Restore (ASR). Server-side NetBoot image can boot entire machines, although NetBoot is more commonly used for operating system and software deployment, somewhat similar to Norton Ghost.
To NetBoot a client machine, hold the "N" key as the Mac boots, or select the NetBoot server using the Startup Disk preference pane (Mac OS X) or control panel (Mac OS 8 and 9). Alternatively, New World Macs can be started with the Command (⌘), Option (⌥), O and F keys pressed to enter the Open Firmware prompt. Once in the Open Firmware one can tell the client to attempt then NetBoot procedure by entering "boot enet:0" and pressing the return key.
Client machines first request network configuration information through DHCP, then a list of boot images and servers with BSDP and then proceed to download images with protocols mentioned above.
Both Intel and PowerPC-based servers can serve images for Intel as well as PowerPC-based clients.

Famous quotes containing the word process:
“To exist as an advertisement of her husband’s income, or her father’s generosity, has become a second nature to many a woman who must have undergone, one would say, some long and subtle process of degradation before she sunk [sic] so low, or grovelled so serenely.”
—Elizabeth Stuart Phelps (1844–1911)
“Because her instinct has told her, or because she has been reliably informed, the faded virgin knows that the supreme joys are not for her; she knows by a process of the intellect; but she can feel her deprivation no more than the young mother can feel the hardship of the virgin’s lot.”
—Arnold Bennett (1867–1931)
“If thinking is like perceiving, it must be either a process in which the soul is acted upon by what is capable of being thought, or a process different from but analogous to that. The thinking part of the soul must therefore be, while impassable, capable of receiving the form of an object; that is, must be potentially identical in character with its object without being the object. Mind must be related to what is thinkable, as sense is to what is sensible.”
—Aristotle (384–322 B.C.)
