    1919  things to do is to ensure that the system can be properly booted. The

     20  instructions below apply only to computers of x86 and x86_64 architecture,

    31   <para os="c">Earlier, we compiled and installed the GRUB boot loader software
    32   in preparation for this step. The procedure involves writing some special
    33   GRUB files to specific locations on the hard drive. We highly recommend
    34   creating a GRUB boot floppy diskette as a backup. Insert a blank floppy
    35   diskette and run the following commands:</para>
     31  <para os="c">The first thing we need to do is generate a configuration for
     32  GRUB. In previous versions of grub we could create the configuration manually
     33  here, but with GRUB2 we can generate <filename>grub.cfg</filename>
     34  automatically. You can do this with the following command:</para>

    37 <screen os="d"><userinput>dd if=/boot/grub/stage1 of=/dev/fd0 bs=512 count=1
    38 dd if=/boot/grub/stage2 of=/dev/fd0 bs=512 seek=1</userinput></screen>

    45   <para os="g">GRUB uses its own naming structure for drives and partitions in
    46   the form of <emphasis>(hdn,m)</emphasis>, where <emphasis>n</emphasis>
    47   is the hard drive number and <emphasis>m</emphasis> is the partition
    48   number, both starting from zero. For example, partition <filename
    49   class="partition">hda1</filename> is <emphasis>(hd0,0)</emphasis> to
    50   GRUB and <filename class="partition">hdb3</filename> is
    51   <emphasis>(hd1,2)</emphasis>. In contrast to Linux, GRUB does not
    52   consider CD-ROM drives to be hard drives. For example, if using a CD
    53   on <filename class="partition">hdb</filename> and a second hard drive
    54   on <filename class="partition">hdc</filename>, that second hard drive
    55   would still be <emphasis>(hd1)</emphasis>.</para>
