Emax

That's strange !

I have an EMAX-II rack without any internal HD.
The only two disk devices connected to this EMAX-II are:
- the internal floppy drive
- an external 100 MB ZIP drive with ID = 6 and terminator = ON.
(the Boot SCSI ID in the Master Module is set to 4 however)

When I boot the EMAX-II without any floppy disk in the drive, but 
with an EMAX-II formatted ZIP disk with OS in the ZIP drive, it boots 
from that ZIP disk !

The EMAX-II always scans the complete SCSI chain if it doesn't find 
an OS on the floppy disk or on the "default SCSI device" set by the 
SCSI ID you mentioned in the Master module. 
This Master setting does not mean that the OS can only be loaded from 
that device. The Master SCSI ID must be set if your EMAX-II has 
multiple HD's (or ZIP disks) each carrying its own OS. In that case, 
you have to tell the EMAX-II which OS device is the preferred 
one/should be used. It indicates the first HD which will be checked 
by the EMAX-II. If no OS resides on that HD, EMAX-II will start the 
SCSI chain search.

So normally you should not have any problem with booting from an 
external ZIP drive. 
(on EMAX-I however, the ZIP drive MUST have SCSI ID = 0)
