/FILE=file
Optional.
Specifies the name of the client's system image or other file to
download upon request.
o By default, upon receiving a request, BOOTP looks for this
file in TCPIP$TFTP_ROOT:[host], where host is the client's
host name, excluding the domain.
o If this directory does not exist, BOOTP uses:
TCPIP$TFTP_ROOT:[000000].
o When the TCP/IP Services software receives a boot request,
BOOTP verifies the existence and size of this file.
