You would need to mount the partition first before running lilo.
Depending on how you plan to configure lilo of course.
There are many ways of achiving what you want, i will explain how i do it.

You describe adding the new 7.2 system into the old 6.2 lilo, i would advise 
against doing that as newer versions of lilo have less problems with just 
about everything, including the 1023 limit as you point out, i dont know what 
limitations the version has included in 6.2.

I would place both systems under the latest version of lilo, that we can do 
as follows.

Boot into 7.2 with your floppy.
login as root
mount the 6.2 root partition into /mnt
mount -t ext2 /dev/hdxx /mnt
cp /mnt/boot/boot_image /boot/vmlinuz-red-6.2
cp /mnt/boot/System.map /boot/System.map-red-6.2
umount /mnt
edit /etc/lilo.conf
Add a new section for the old 6.2 install.
run lilo with the -t option to check if things are ok.
If all is ok run lilo again to install the new configuration.
reboot now you can choose which system you want.

If you need an example take a look at;
