Emax

You're right... booting does not work the same when SCSI ID is set to 
0. 
When SCSI ID is set to 0, the EMAX-II only wants to boot from floppy 
disk and it does not check the SCSI chain.
When SCSI ID is set to any other value, the EMAX-II will first try 
the preferred boot SCSI ID and afterwards also try all other 6 IDs.
In that case, if a bad formatted ZIP disk is present in the ZIP 
drive, there's still a bit of activity on the ZIP drive every time 
EMAX-II checks the ZIP drive.
Note also that EMAX-II always shows the SCSI ID it is checking on its 
display. If your display only shows "Insert Disk", this means that 
the SCSI ID had been set to 0 and that EMAX-II is not checking the 
SCSI chain.

Unfortunately I guess this is your problem. That's a pitty. 
I have no idea if it is possible to disconnect the flat cable of your 
floppy drive and put any other SCSI device on that port (internally, 
e.g. an internal ZIP drive with ID set to 0). I guess not...

Anyway, good luck !
