-A simple trick is to copy your vmm.img and whatever else *to* $QEMU

-do the following, adapting it to your local environment.
-
-To develop on windows, you will install:
-
-- a specific version of binutils (targetting i386-elf)
-- a specific version of gcc (targetting i386-elf)
-- a specific version of nasm, patched for VT and SVM instructions
-- the as86, bcc, and ld86 tools from Dev86 (these are needed to build
-the bioses and other vm boot package components)
-
-
-To start, install cygwin (see cygwin.org).  We have done a complete
-installation ("all" -> "install") in our environment, and would
-recommend it. 
-
-Run a bash shell.
-
-Check out vmm-dev from CVS, or unpack a copy from a tarball.  
-In the following, we assume /home/pdinda/Codes/vmm-dev
-is the checked-out directory
-
-export DEVROOT=/home/pdinda/Codes/vmm-dev
-mkdir $DEVROOT/devtools
-export LOCATION=$DEVROOT/devtools

-./configure --prefix=$LOCATION/i386 --target=i386-elf --disable-nls
-make -j 4 all

-# $Revision: 1.71 $
-
-
-# This is free software.  You are permitted to use,
-# redistribute, and modify it as specified in the file "COPYING".
-
-# Required software to build GeekOS:
-# - GNU Make (http://www.gnu.org/software/make)
-# - gcc 2.95.2 generating code for target (i386/ELF) and host platforms
-# - Perl5, AWK (any version), egrep
-#
-# Cygwin (http://cygwin.com) may be used to build GeekOS.
-# Make sure that gcc, binutils, nasm, and perl are installed.
-
-# NOTES:
-# - This makefile has been written carefully to work correctly
-#   with the -j (parallel make) option.  I regularly use "make -j 2"
-#   to speed the build process on 2 processor systems.

-
-# Base address of kernel
-#
-# Note: at top of memory minus three pages (GDT/TSS/IDT) 
-# minus maximum size
-#
-#
-# Note that the code will initially load at 0x10000

+ * "Optimize" a list of dependencies as spit out by gcc -MD
+ * for the kernel build
+ * ===========================================================================
+ *
+ * Author       Kai Germaschewski
+ * Copyright    2002 by Kai Germaschewski  <kai.germaschewski@gmx.de>
+ *
+ * This software may be used and distributed according to the terms
+ * of the GNU General Public License, incorporated herein by reference.
+ *
+ *
+ * Introduction:
+ *
+ * gcc produces a very nice and correct list of dependencies which
+ * tells make when to remake a file.
+ *
+ * To use this list as-is however has the drawback that virtually
+ * every file in the kernel includes <linux/config.h> which then again
+ * includes <linux/autoconf.h>
+ *
+ * If the user re-runs make *config, linux/autoconf.h will be
+ * regenerated.  make notices that and will rebuild every file which
+ * includes autoconf.h, i.e. basically all files. This is extremely
+ * annoying if the user just changed CONFIG_HIS_DRIVER from n to m.
+ *
+ * So we play the same trick that "mkdep" played before. We replace
+ * the dependency on linux/autoconf.h by a dependency on every config
+ * option which is mentioned in any of the listed prequisites.
+ *
+ * To be exact, split-include populates a tree in include/config/,
+ * e.g. include/config/his/driver.h, which contains the #define/#undef
+ * for the CONFIG_HIS_DRIVER option.
+ *
+ * So if the user changes his CONFIG_HIS_DRIVER option, only the objects
+ * which depend on "include/linux/config/his/driver.h" will be rebuilt,
+ * so most likely only his driver ;-)
+ *
+ * The idea above dates, by the way, back to Michael E Chastain, AFAIK.
+ *
+ * So to get dependencies right, there are two issues:
+ * o if any of the files the compiler read changed, we need to rebuild
+ * o if the command line given to the compile the file changed, we
+ *   better rebuild as well.
+ *
+ * The former is handled by using the -MD output, the later by saving
+ * the command line used to compile the old object and comparing it
+ * to the one we would now use.
+ *
+ * Again, also this idea is pretty old and has been discussed on
+ * kbuild-devel a long time ago. I don't have a sensibly working
+ * internet connection right now, so I rather don't mention names
+ * without double checking.
+ *
+ * This code here has been based partially based on mkdep.c, which
+ * says the following about its history:
+ *
+ *   Copyright abandoned, Michael Chastain, <mailto:mec@shout.net>.
+ *   This is a C version of syncdep.pl by Werner Almesberger.
+ *
+ *
+ * It is invoked as
+ *
+ *   fixdep <depfile> <target> <cmdline>
+ *
+ * and will read the dependency file <depfile>
+ *
+ * The transformed dependency snipped is written to stdout.
+ *
+ * It first generates a line
+ *
+ *   cmd_<target> = <cmdline>
+ *
+ * and then basically copies the .<target>.d file to stdout, in the
+ * process filtering out the dependency on linux/autoconf.h and adding
+ * dependencies on include/config/my/option.h for every
+ * CONFIG_MY_OPTION encountered in any of the prequisites.
+ *
+ * It will also filter out all the dependencies on *.ver. We need
+ * to make sure that the generated version checksum are globally up
+ * to date before even starting the recursive build, so it's too late
+ * at this point anyway.
+ *
+ * The algorithm to grep for "CONFIG_..." is bit unusual, but should
+ * be fast ;-) We don't even try to really parse the header files, but
+ * merely grep, i.e. if CONFIG_FOO is mentioned in a comment, it will
+ * be picked up as well. It's not a problem with respect to
+ * correctness, since that can only give too many dependencies, thus
+ * we cannot miss a rebuild. Since people tend to not mention totally
+ * unrelated CONFIG_ options all over the place, it's not an
+ * efficiency problem either.
+ *
+ * (Note: it'd be easy to port over the complete mkdep state machine,
+ *  but I don't think the added complexity is worth it)
+ */
+/*
+ * Note 2: if somebody writes HELLO_CONFIG_BOOM in a file, it will depend onto
+ * CONFIG_BOOM. This could seem a bug (not too hard to fix), but please do not
+ * fix it! Some UserModeLinux files (look at arch/um/) call CONFIG_BOOM as
+ * UML_CONFIG_BOOM, to avoid conflicts with /usr/include/linux/autoconf.h,
+ * through arch/um/include/uml-config.h; this fixdep "bug" makes sure that
+ * those files will have correct dependencies.

+ *
+ *      Table compression uses all the unused char codes on the symbols and
+ *  maps these to the most used substrings (tokens). For instance, it might
+ *  map char code 0xF7 to represent "write_" and then in every symbol where
+ *  "write_" appears it can be replaced by 0xF7, saving 5 bytes.
+ *      The used codes themselves are also placed in the table so that the
+ *  decompresion can work without "special cases".
+ *      Applied to kernel symbols, this usually produces a compression ratio

+ *
+ *  [ 1998-06-13 ]
+ *
+ *    *)  A bugfix for the Page-Down problem
+ *
+ *    *)  Formerly when I used Page Down and Page Up, the cursor would be set 
+ *        to the first position in the menu box.  Now lxdialog is a bit
+ *        smarter and works more like other menu systems (just have a look at
+ *        it).
+ *
+ *    *)  Formerly if I selected something my scrolling would be broken because
+ *        lxdialog is re-invoked by the Menuconfig shell script, can't
+ *        remember the last scrolling position, and just sets it so that the
+ *        cursor is at the bottom of the box.  Now it writes the temporary file
+ *        lxdialog.scrltmp which contains this information. The file is
+ *        deleted by lxdialog if the user leaves a submenu or enters a new
+ *        one, but it would be nice if Menuconfig could make another "rm -f"
+ *        just to be sure.  Just try it out - you will recognise a difference!
+ *
+ *  [ 1998-06-14 ]
+ *
+ *    *)  Now lxdialog is crash-safe against broken "lxdialog.scrltmp" files
+ *        and menus change their size on the fly.
+ *
+ *    *)  If for some reason the last scrolling position is not saved by
+ *        lxdialog, it sets the scrolling so that the selected item is in the
+ *        middle of the menu box, not at the bottom.
+ *
+ * 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
+ * Reset 'scroll' to 0 if the value from lxdialog.scrltmp is bogus.
+ * This fixes a bug in Menuconfig where using ' ' to descend into menus
+ * would leave mis-synchronized lxdialog.scrltmp files lying around,
+ * fscanf would read in 'scroll', and eventually that value would get used.
