bootaddhdr(1M)                                               bootaddhdr(1M)


   NAME
         bootaddhdr - add bootstrap header

   SYNOPSIS
         bootaddhdr [-d] -p loadpoint -e entrypoint -f inputfile -o outputfile
         -m messagestring

   DESCRIPTION
         bootaddhdr adds a 512 byte header to the front of inputfile and
         writes the resulting file to outputfile.  This header is examined by
         the second stage bootstrap in order to load and execute the third
         stage bootstrap. The information in the header consists of a message
         string, a load point and an entry point. The options are used to set
         the header values.  Newboot uses bootaddhdr to install the third
         stage bootstrap on the boot partition on the hard disk.

   OPTIONS
         -p loadpoint
               Sets the memory address for the location of the third stage
               bootstrap. Loadpoint is in hexadecimal.

         -e entrypoint
               Sets the value that will be loaded into the program counter to
               start the execution of the third stage bootstrap.  Entrypoint
               is in hexadecimal.

         -f inputfile
               The file containing data to be appended after the header. This
               should contain a raw binary file, one that has been created by
               image.

         -o outputfile
               The file that will be created that contains the header and the
               contents of the inputfile.

         -m messagestring
               Sets the string that will be printed on the video screen at
               boot time.

         -d    Sets a debugging flag.
