The first phase: the diskless remote node discovers its
network identify and the name of the file to be booted
The second phase: the diskless remote node reads the boot
file across the network into its memory
The various modules (capabilities) and the dependencies of these
modules that support the overall network boot function are
described in the following paragraphs
This driver manages/surrounds the Intel 82596 LAN Coprocessor.
Management is in the scope of:
Reception of packets
Transmission of packets
Receive buffer flushing
Interface initialization
This module ensures that the packaging and unpackaging of
Ethernet packets is performed correctly in the Boot PROM.
The Internet Protocol (IP) is designed for use in interconnected
systems of packet-switched computer communication networks.
The Internet protocol provides for transmitting of blocks of data
called datagrams (hence User Datagram Protocol, or UDP) from
sources to destinations, where sources and destinations are hosts
identified by fixed length addresses.
The UDP/IP protocols are necessary for the TFTP and BOOTP
protocols; TFTP and BOOTP require a UDP/IP connection.
