Look at the "Partition Type Change Rules" section of the Lilo manual.
For each defined image you can specify that certain partitions be hidden
or unhidden.  You can also define what "Hidden" means, so enabling you
(for example) to change the type of a partition to something that
DOS/Win9x will ignore.  In this way you could make the first Win98
partition invisible when booting from the second one.

Lilo can do that:

  map-drive = 0x80
      to = 0x81
  map-drive = 0x81
      to = 0x80

That assumes the Win98 partitions are on /dev/hda and /dev/hdb
respectively.  The result will be that each Win98 installation will see
the contents of the othe partition as drive D:
