   4 #       This script can be used to convert bootptab files in old format
   5 #       to new (termcap-like) bootptab files
   6 #
   7 # The old format - real entries are commented out by '###'
   8 #
   9 # Old-style bootp files consist of two sections.
  10 # The first section has two entries:
  11 # First, a line that specifies the home directory
  12 # (where boot file paths are relative to)
  13
  14 ###/tftpboot
  15
  16 # The next non-empty non-comment line specifies the default bootfile
  17
  18 ###no-file
  19
  20 # End of first section - indicated by '%%' at the start of the line
  21
  22 ###%%
  23
  24 # The remainder of this file contains one line per client
  25 # interface with the information shown by the table headings
  26 # below. The host name is also tried as a suffix for the
  27 # bootfile when searching the home directory (that is,
  28 # bootfile.host)
  29 #
  30 # Note that htype is always 1, indicating the hardware type Ethernet.
  31 # Conversion therefore always yields ':ha=ether:'.
  32 #
  33 # host  htype   haddr   iaddr   bootfile
  34 #
  35
  36 ###somehost     1       00:0b:ad:01:de:ad       128.128.128.128 dummy
  37
  38 # That's all for the description of the old format.
  39 # For the new-and-improved format, see bootptab(5).
