You have me a little confused with what you've written.
You say that you've already created a bootable floppy. Insert that floppy into floppy drive A: and boot the system. It should then display a command prompt A:> which is its way of asking what command you'd like to execute next. So yes, it's going to wait for you to give it a command.
You create a bootable floppy from a DOS environment or from a DOS window by typing the command
FORMAT A: /s
This writes a system to the floppy so that when you reboot it boots to the floppy rather than the C: drive.
Do things work now?
