SETNETBOOTINFO(8)   OpenBSD System Manager's Manual (Alpha)  SETNETBOOTINFO(8)

NAME
     setnetbootinfo - configure network bootstrap program

SYNOPSIS
     setnetbootinfo [-vf] [-o infile] [-a ether-address | -h ether-host]
		    netboot
     setnetbootinfo [-v] -u -o outfile infile

DESCRIPTION
     The setnetbootinfo utility configures the OpenBSD/alpha network bootstrap
     program so that it can be used to bootstrap systems with old firmware
     revisions.

     The OpenBSD/alpha network bootstrap program needs to have the Ethernet
     address of the interface being used to boot the system available when
     querying other hosts on the network for bootstrapping information.	 Alpha
     systems with old firmware revisions provide no way for network bootstrap
     programs to determine the Ethernet address of the interface that they are
     booting from, and so the OpenBSD/alpha network bootstrap program must
     find that information in another way.  (Newer firmware revisions include
     the Ethernet address in the name of the device that is being booted
     from.)  The setnetbootinfo utility encodes an Ethernet address (and other
     information) directly into the network bootstrap program.

     The options recognized by setnetbootinfo are as follows:

     -a ether-address
	   Encode the given Ethernet address into the network bootstrap
	   program.  (This option and the -h option are mutually exclusive.)

     -f	   Force the address information being encoded in the bootstrap
	   program to be used regardless of whether or not the bootstrap
	   program can get address information from the booting system's
	   firmware.

     -h ether-host
	   Encode the Ethernet address of the specified host into the network
	   bootstrap program.  The host's name is translated to an Ethernet
	   address using the ether_hostton(3) function.	 (This option and the
	   -a option are mutually exclusive.)

     -o outfile
	   Output the resulting bootstrap program into the file named by
	   outfile, replacing it if it already exists.	If the -o flag is not
	   specified, the output file name will be the name of the input
	   bootstrap program concatenated with a period and the digits of the
	   Ethernet address being encoded.  For instance, if the input file is
	   named /usr/mdec/netboot and is being configured to encode the
	   Ethernet address 08:00:2b:bd:5d:fd, then the default output file
	   name would be /usr/mdec/netboot.08002bbd5dfd.  It is safe to set
	   the output file name to be the same as the input file name; the
	   input file is read in its entirety before the output file is
	   modified.

     -u	   Remove configuration information from the specified network
	   bootstrap program.  If this option is used, an output file name
	   must be specified with the -o option, and neither the -a or the -h
	   options may be specified.

     -v	   Verbose mode.
