How do I boot FreeBSD and Linux from LILO? How do I boot FreeBSD and Linux from LILO?

<p>Theoretically you should be able to boot FreeBSD from LILO by <p>If you have FreeBSD and Linux on the same disk, just follow

able to get it to work. If you put LILO at the start of your Linux system. Very briefly, these are:
boot partition instead of in the MBR, you can boot LILO from the
FreeBSD boot manager. This is what I do. <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

to automatically do this for you at boot time.
<p>The <htmlurl

name="Linux+FreeBSD mini-HOWTO"> is a good reference for
FreeBSD and Linux interoperability issues.

<p>Install LILO at the start of your Linux boot partition instead of
