Install LILO in the Linux root partition (i.e., /dev/sda3),
not into the MBR. You can, however, configure a choice
of different Linux kernel images for LILO. You can do this with the following
/etc/lilo.conf:
# LILO configuration file
# Start LILO global Section
boot=/dev/sda3 # where LILO should be installed
backup=/boot/boot.sda3.970428 # Backup of the previous boot sector
prompt
timeout=100 # wait at prompt: 10 s
vga = normal # force sane state
# End LILO global section
# Linux bootable partition config begins
image = /vmlinuz # default image to boot
root = /dev/sda3 # root partition is here
label = Linux
# Linux bootable partition config ends
# Name other Linux kernel images here:
# ...
Install LILO as usual with /sbin/lilo.
