Ämne: Re: [emax] Looking for Emax OS 3.2 blank floppies



 

ok 3.2 is for non upgraded se machines it wont work
in se or se/hd or plus os
 
it will come up as wrong os disc the same if you
try and load a plus disk into a standard se with no scsi
the pre se models that were hd scsi compatible had
there own os and only worked on that version
 
for scsi upgrades you needed to upgrade the machine
to se first before you could load the scsi os version roms and a special pal
chip for doing the scsi
 
the se added the spectral synthesis so any banks
that contain that will not load into a os3.2 machine
 
the plus os was used for the emaxes that had the
external port so you could change the port to an external device other than scsi
id0 which is the only id that the emax can boot from  this allowed more
than 1 scsi device on the bus and so it allowed you to change the id so you
could load banks from any device id that had a scsi device attached up to 7
devices to the 8 device id network there is always one taken by the
controller
 
thats why you can only attach 7 devices
 
each manufacturer used there own device id some use
7 some use 3 like the ensoniqs
 
but eve3n though you had the plus os when you
switch the machine off the external scsi id of your device is not kept and so
when switch on it reverts back to scsi id0 for booting the emax os from scsi
device
 
this is a problem if your thinking of boot your
machine from an external zip drive which can only use scsi id5/6 so you would
need to always have a floppy to boot your machine if using such
devices
 
if you have an internal scsi zip drive with a
external case then these can be set to scsi id0
 
if you have the version of femax with the external
25db scsi port you will need the scsi plus os disks
