in order to boot more than one kernel by the same floppy disk you should
use LILO which is the standard Linux bootloader. Read Bootdisk-HOWTO on
how to create the appropriate /etc/lilo.conf for a floppy (it is trivial
unless you use 2.88M floppy images built in the ramdisk, in which case you
need to specify some very magic numbers in geometry that I can supply you
with).
as for the answer to your question (though you do NOT need this) is - to
find the actual sectors the kernel is located on you use the FIBMAP ioctl.
