I am not an expert but you could try the following:
Edit the lilo.conf file and put in the following
disk=/dev/sda
bios=0x80
# boot=/dev/hda (get rid of this and change to the following)
boot=/dev/sda
root=/dev/sda7
install=/boot/boot.b
map=/boot/map
... then the rest of your lilo.conf ...
You could also experiment with the linear option - it may be needed.
Basically IIRC the first line tells lilo the geometry of the boot disk
(dev/sda7) and the second line tells it to treat the sda7 device as the
first bios hard disk (0x80) and boot from this.
Then rerun lilo
Hopefully, this will allow you to install lilo on your scsi disk and
allow you to boot from it.
Good luck.
ps I don't have any scsi devices so not sure.
Mark.
