  <title>Building a bootloader</title>

    <para>On x86 and x86_64 (multilib) architectures, the preferred
      bootloader is GRUB.  Unfortunately, GRUB doesn't work on x86_64
      Pure64 - the stage2 files can be correctly built as 32-bit, but the
      <command>grub</command> shell is a 64-bit program, and tries to
      execute some of the stage2 routines - this results in a segmentation
      fault. Therefore, in the final system we use Lilo as the bootloader.
    </para>

    <para>If you already have a bootloader, such as GRUB, installed on
      the system then you should use that to make your new kernel bootable.
   </para>

  <note>
    <para>We will now cross-compile Bin86 and Lilo - these instructions 
      assume you are using an x86_64 machine (e.g. booted fron a Live CD),
      either pure64 or multilib. This approach will not work if you are
      running the machine as i686, because a 32-bit kernel will not be
      able to execute a 64-bit binary to install the bootloader.  If that
      is the case, you will need to install an i686 bootloader on the
      host system.
