         How do I boot FreeBSD and Linux from LILO?
       </heading>
 
-      <p>Theoretically you should be able to boot FreeBSD from LILO by
-      treating it as a DOS-style operating system, but I haven't been
-      able to get it to work. If you put LILO at the start of your Linux
-      boot partition instead of in the MBR, you can boot LILO from the
-      FreeBSD boot manager. This is what I do.
+      <p>If you have FreeBSD and Linux on the same disk, just follow 
+      LILO's installation instructions for booting a non-Linux operating 
+      system.  Very briefly, these are:
+
+      <p>Boot Linux, and add the following lines to 
+      <tt>/etc/lilo.conf</tt>:
+      <verb>
+      other=/dev/hda2
+	      table=/dev/hda
+	      label=FreeBSD
+      </verb>
+      (the above assumes that your FreeBSD slice is known to Linux as 
+      <tt>/dev/hda2</tt>; tailor to suit your setup).  Then, 
+      run <tt>lilo</tt> as root and you should be done.
+
+      <p>If FreeBSD resides on another disk, you need to add 
+      ``<tt>loader=/boot/chain.b</tt>'' to the LILO entry.  
+      For example:
+      <verb>
+      other=/dev/sdb4
+	      table=/dev/sdb
+	      loader=/boot/chain.b
+	      label=FreeBSD
+      </verb>
+
+      <p>In some cases you may need to specify the BIOS drive number 
+      to the FreeBSD boot loader to successfully boot off the second disk.  
+      For example, if your FreeBSD SCSI disk is probed by BIOS as BIOS 
+      disk 1, at the FreeBSD boot loader prompt you need to specify:
+      <verb>
+      Boot: 1:sd(0,a)/kernel
+      </verb>
+
+      <p>On FreeBSD 2.2.5 and later, you can configure <htmlurl 
+      url="http://www.freebsd.org/cgi/man.cgi?boot(8)" name="boot(8)">
+      to automatically do this for you at boot time.
+
+      <p>The <htmlurl 
+      url="http://sunsite.unc.edu/LDP/HOWTO/mini/Linux+FreeBSD.html"
+      name="Linux+FreeBSD mini-HOWTO"> is a good reference for
+      FreeBSD and Linux interoperability issues.

+	How do I boot FreeBSD and Linux using BootEasy?
+      </heading>
+
+      <p>Install LILO at the start of your Linux boot partition instead of 
+      in the Master Boot Record.   You can then boot LILO from BootEasy.
 
       <p>If you're running Windows-95 and Linux this is recommended anyway,
       to make it simpler to get Linux booting again if you should need
