update 2:Argh!!! I tried reformatting the internal CF and copying the OS from the floppy to it. Now when I start up off the floppy and load a bank, I can not access ANY of the modules - every button push brings me to "Bank does not exist!" no matter what I try. It boots from the floppy, and sees the internal CF and external ZIP drive, but will not go into any module. Do I need to open it up and reset the internal drive somehow? So frustrating...
I remember having similar problem on one of mine.
I think the reason it says "Bank don´t exist" is that is looking for a OS where it don´t exist
probably at some of the scsi devices but not at the floppy were it should.
Which scsi ID has the internal drive?
Which scsi ID has the EIII?
Did the midi died also without the external Zip connected?
You should try to install a working OS on the internal
and boot from that without the zip connected an see if that works.
