FLOPPY startup will only load into the bottom 640K and will only use
memory in that area. It is really only intended for use with RedBoot,
although applications that can live in 640K will work too.

To run applications above 1M either load RAM startup applications with
a FLOPPY RedBoot, use a GRUB-loaded RedBoot to load them, or load the
application directly using a GRUB startup type.
