Emax

I bought some external HD, preloaded with sounds... super...

But when I connected it in nothing "no scsi drive om ID2 was found". 
I set the ID (external HD) to "2" as well but...... Where is the 
troble? And how to get the OS 2.14 dikette. (not "emx" , I didn`t 
have luck to get the new OS with emx programm into the EMAX) 

Need help!
