You shouldn't need the emergency floppy to just format the HD.
That's true. But after you have formatted your boot partition, there is nothing you can do with the computer any more, because you have no boot disk and no drivers to access the CD. Sounds quite stupid to me.
To get the emergency disk find the CD-ROM drive, make sure all parts of the CD-ROM drivers are available. Load the file Devs/DosDrivers/CD0 or Devs/DosDrivers/EMERGENCY_CD (whatever it is called) into a text editor.
Read the lines FileSystem=
and Device=. Check that is present in the L directory of the emergency disk and that is either the name of your countroller's firmware driver or is present as file in the Devs directory.
Also make sure, if you need additional driver programs like IDEfix or SpeedUP, that these are in the C directory of the emergency disk and that they are called in S/Startup-Sequence.
