Boot File
This is the file referenced in the BOOTFILE field of the BOOTP reply message.
A boot file provides configuration information for a network device either by
containing an executable code image for the device or by listing the names of
other files that contain the code image and other configuration information.
Boot Image
The configuration information delivered as the result of the boot process.
Includes all information derived from the BOOTP reply, boot file, and associated
hosts, services, and code files.
BOOTP
Boot protocol. The communication protocol used to transfer initialization
information between digital headend network elements and a central server.
At power up, network elements issue a BOOTP request. The BOOTP server
receives the request and responds with a BOOTP reply that specifies startup
information and operating parameters for the requesting device.
BOOTP Reply

The RADD 6000 inserts these messages into the EMM data stream that is
distributed out-of-band.
