I have added several new items into the Updates section. Namely, GRUB is officially at version 1.99 and comes with a few more changes. The important cosmetic fix is that additional, older versions of the kernel are all listed under a single directory-like entry, making the menu easier to read. Moreover, Ubuntu comes with a high-resolution menu and smaller font size. But that's not all. We also have Fedora 16 Verne changes. We learn how to update the GRUB configuration file and how to edit default entry and timeout in the boot menu inside the 00_header script. If you feel there ought to be a whole new and separate Fedora tutorial, do shout. Finally, we also discuss Xen setup in a multi-boot configuration.
