+>It is not always possible to boot a computer from the hard disk.
+ For example, if you make a mistake in configuring LILO, you might
+ make your system unbootable. For these situations, you need an
+ alternative way of booting that will always work (as long as the
+ hardware works). For typical PC's, this means booting from the
+ floppy drive.</P
+><P
+>Most Linux distributions allow one to create an
+ <I
+CLASS="GLOSSTERM"
+>emergency boot floppy</I
+> during installation.
+ It is a good idea to do this. However, some such boot disks
+ contain only the kernel, and assume you will be using the programs
+ on the distribution's installation disks to fix whatever problem
+ you have. Sometimes those programs aren't enough; for example,
+ you might have to restore some files from backups made with
+ software not on the installation disks.</P
+><P
+>Thus, it might be necessary to create a custom root floppy
+ as well. The <I
+CLASS="CITETITLE"
+>Bootdisk HOWTO</I
+> by Graham
+ Chapman (XXX citation) contains instructions for doing this.
+ You must, of course, remember to keep your emergency boot and
+ root floppies up to date.</P
+><P
+>You can't use the floppy drive you use to mount the root
+ floppy for anything else. This can be inconvenient if you only
+ have one floppy drive. However, if you have enough memory, you
+ can configure your boot floppy to load the root disk to a ramdisk
+ (the boot floppy's kernel needs to be specially configured for
+ this). Once the root floppy has been loaded into the ramdisk,
+ the floppy drive is free to mount other disks. </P
