From man lilo.conf:

disk=<device-name>
Defines non-standard parameters for the specified disk. See sec-
tion "Disk geometry" of user.tex for details. Especially useful
is the `bios=' parameter. The BIOS numbers your disks 0x80, 0x81,
etc. and it is impossible to decide which Linux disk corresponds
to which BIOS disk (since this depends on the BIOS setup, and on
the type of BIOS), so if you have an unusual setup you need to
state the correspondence between Linux disks and BIOS disks. For
example,

disk=/dev/sda
bios=0x80
disk=/dev/hda
bios=0x81

would say that your SCSI disk is the first BIOS disk, and your
(primary master) IDE disk is the second BIOS disk. Other options
include the specification of disk geometry; e.g.,

disk=/dev/fd0
sectors=18
heads=2
cylinders=80
With that in mind, try this:

sudo /sbin/lilo -v3 -t

That should tell you what you need to enter in LILO.

Try something like this for example:

disk=/dev/hde
bios=0x80

disk=/dev/hdg
bios=0x81
