-+[PATCH] - Make GRUB recognize and boot an x86_64 elf image
-+
-+
-+HOW IT WORKS
-+------------
-+* Grub interface is unchanged.
-+* Upon passing an elf-x86_64 file via "kernel=", GRUB will load and parse it
-+ correctly.
-+* Upon the "boot" directive, GRUB will switch from protected 32-bit
-+ mode to long 64-bit mode and transfer control to the image's entrypoint.
-+
-+
-+INSTALL
-+-------
-+cd grub-0.97
-+patch -p1 < grub-x86_64-elf.patch
-+./configure
-+make
-+su -c "make install"
-+
-+Note: You do not need to re-install your bootsectors, but you WILL need
-+ to copy the modified stage2 file(s) from /usr/share/grub to
-+ your actual boot filesystem (usually /boot/grub for GNU/Linux).
-+
-+
-+WHY?
-+----
-+Because in our world, all elves and elf images are created equal, and have
-+been endowed with the ability to be bootable. :-)
-+
-+
-+THE NITTY GRITTY - GRUB SIDE
-+----------------------------
-+* Since paging is manditory in 64-bit long mode, the first 4GB of physical
-+ memory (whether present or not) is identity mapped into the linear
-+ address space using 2MB pages.
-+* Paging data structures are written to physical 0x70000-0x75fff in the
-+ same area reserved for the raw device buffer. This happens after the
-+ "boot" command is issued so the raw device buffer won't mind. Paging
-+ can be relocated and reconfigured after the kernel is running.
-+* Header files have been added to describe the x86_64 elf image structure.
-+
-+
-+THE NITTY GRITTY - KERNEL SIDE
-+------------------------------
-+* Parameters passed to the assembly entrypoint are unchanged including
-+ magic number and pointer to multiboot info structure.
-+* The assembly entrypoint should be designated as ".code64".
-+* The Global Descriptor Table (GDT) shared by the GRUB and KERNEL sides
-+ has been expanded to include 3 additional 64-bit ('L' bit set) segments:
-+ 0x28 (code) and 0x30 (data).
-+* An updated "multiboot.h" file is provided to reflect the difference in
-+ "unsigned long" sizes between i386 and x86_64 architectures for use by
-+ the client kernel.
-+
-+
-+CAVEATS
-+-------
-+Possible collisions with existing GRUB patch sets are unknown. Use "darcs"
-+and worry not.
-+
-+ http://abridgegame.org/darcs
-+
-+(An intelligent alternative to cvs and greying hair in the distributed
-+post-mainframe age.)
-+
-+
-+DOCUMENTATION CHANGES
-+---------------------
-+This is it. Sorry, stuff to do.
-+
-+
-+APOLOGIES TO GRUB2
-+------------------
-+We would have liked to use GRUB2 for this, but needed it today for our
-+kernel. Of course there is probably no technical reason why this
-+functionality cannot be in included in GRUB2 at a future time. Thank you
-+for a way cool bootloader and may all your boots be bogon (and Vogon) free.
