Classic from Jaguar?

[Meirion Roscoe]

I have just installed Jaguar on my cube but am unable to run any 
classic apps.  When I try it says
' Classic startup found no system folder on the boot volume from which 
to start Classic'

then goes on to tell me to install 9.1 from a disk.  I only have a 9.04 
disk and the 9.1 in compressed download form on the hard drive.  Any 
ideas how I can get Classic back on to the Cube.  I still have my iMac. 
  Can I transfer it via firewire somehow?

Thanks
