  14 # This is free software.  You are permitted to use,
  15 # redistribute, and modify it as specified in the file "COPYING".
  16
  17 # Required software to build GeekOS:
  18 # - GNU Make (http://www.gnu.org/software/make)
  19 # - gcc 2.95.2 generating code for target (i386/ELF) and host platforms
  20 # - Perl5, AWK (any version), egrep
  21 #
  22 # Cygwin (http://cygwin.com) may be used to build GeekOS.
  23 # Make sure that gcc, binutils, nasm, and perl are installed.
  24
  25 # NOTES:
  26 # - This makefile has been written carefully to work correctly
  27 #   with the -j (parallel make) option.  I regularly use "make -j 2"
  28 #   to speed the build process on 2 processor systems.

  34 # minus maximum size

  37 # Note that the code will initially load at 0x10000
