+2005-12-01 Alex Williamson <alex.williamson@hp.com>
+	* Applied patch from Fred Yang <fred.yang@intel.com> to support the
+	  vmm= boot option.  This option specifies the kernel image for a
+	  virtual machine monitor (aka hypervisor).  The vmm= and image=
+	  options are used together to load both the hypervisor kernel and
+	  the guest domain kernel into memory.  If a vmm= option is not
+	  specified, elilo defaults to the old behavior of loading and booting
+	  to the image= kernel.
+	* Added support for compressed image= files when used with the vmm=
+	  option.  If the image= file is detected to be gzip compressed, the
+	  image will be uncompressed into memory before it is provided to the
+	  hypervisor.  Any combination of compressed and uncompressed images
+	  can be used for the image and vmm options.
+2005-09-15 Brett Johnson <brett@hp.com>
+	* Applied patch from Tristan Gingold to add dcache flush and sync with
+	  icache to gzip and plain loaders.  This ommision was just noticed now
+	  due to the much larger caches in Montecito, and the smaller size of
+	  Xen (as compared to the linux kernel).
+2004-09-27 Brett Johnson <brett@hp.com>
+	* Increase the hardcoded size of the texmenu chooser menu from 16 to 64
+2004-09-23 Brett Johnson <brett@hp.com>
+	* Fix for 924147.  Thanks to Stephanie Schaaf <sas@sgi.com> for a patch
+	  that the fix is based on.
 2004-02-19 Brett Johnson <brett@hp.com>
 	* Fixed bug where default image initrd would carry over to another
 	  image that was selected interactively (iff the newly selected image
