What LI means: LI
The first stage boot loader was able to load the second stage boot loader,
but has failed to execute it. This can either be caused by a geometry
mismatch or by moving /boot/boot.b without running the map installer.
What I think is that you need to have the /boot directory with all its files
on the boot=/dev/???. The two important files are /boot/map and /boot/boot.b
. With the option map=/boot/map and install=/boot/boot.b you can specify
where those two files are, but only relative two boot=/dev/???. (At least
that's my understanding)
What I suggest is create a small partition with the contends of the /boot
directory say /dev/hda1, and mount /dev/hda1 under /boot. And try to
configure as follows,
boot=/dev/hda1
map=/boot/map
install=/boot/boot.b
root=dev/hdc
...
You could first try this on a floppy (so that you don't need to
repartition). I don't know whether it is possible to actually keep the files
in /boot on a dos or vfat partition (might be another possibility)
For further information:

These are standard HOWTO's that you should also have on your system.
