 (1) - create a 'BOOT' directory on one of your DOS partitions.  (It
       does not have to be named 'BOOT').
 (2) - Make sure that your DOS partition (the one with the BOOT
       directory) is mounted in linux.  You can do this with an entry
       in '/etc/fstab'.
 (3) - While running linux:
	  cp /boot/*  /DOS/BOOT  ## change the destination to the appopriate name
	  mv /boot /boot.old
	  ln -s /DOS/BOOT /boot  ## again, substitute the appropriate name
				 ## for the DOS directory.
 (4) - copy your linux kernel to the /boot directory (now symlinked
       to the directory in the DOS partition.  This may already have
       been done if you have a redhat system, which puts kernels in
       '/boot'.
 (5) - Edit /etc/lilo.conf.  Make sure that the kernel listed is the
       one in '/boot'.
 (6) - /sbin/lilo
 
Keep a boot floppy handy.  If you ever defrag your DOS partition, LILO
will fail until you rerun '/sbin/lilo'.

The point of all of the above is to keep everything needed during
boot in the first 1023 cylinders.
