[WinMac] Change a Mac's SCSI controller ID# ?

Hello all,

We recently obtained a stand alone CD duplicator which we have been able
to use as a duplicator but you're also suppose to be able to use it as a
normal CD writer by connecting it to a computer. I have tried it on
three different PowerMacs, as the only thing on the external SCSI chain,
with nothing else set to the same SCSI ID 6, and no matter what I get
the same errors and they occur immediately upon trying to write a CD.
Those errors are:

      Sense Key = HARDWARE ERROR
      Sense Code = 0x44
      Internal Controller Error

and then after I get past that I get another error:

      Sense Key = ILLEGAL REQUEST
      Sense Code = 0x2C
      Command Sequence Error

At which point the whole system locks up and I have to do a force reboot
(Cmd+Opt+Power Key) in order to get out of it. The unit seems to work
fine when duplicating existing CDs as we've done both Mac CDs and
Windows CDs flawlessly. We have just not been able to use it to write a
custom CD. I emailed the company's tech support and he replied back
with the following:

-----

> The controller for the duplicator is set to ID #7 and your internal
> controller is set to 7 also. You will have to change the id number
> of your internal controller to another number.

To which I replied back:

-----

I sure didn't see anything about that in the book or on your website but
I can see where that might make a big difference. I know how to change
the SCSI ID of an Adaptec SCSI card in a PC but how do you do that with
the built-in motherboard SCSI on a Macintosh? I thought that was fixed!

So WinMac gurus; is it possible to change a Mac's internal SCSI
controller ID? If not any ideas on how I might get this thing to work?
The duplicator unit has no way to change the SCSI ID of even the CD
writer let alone it's SCSI controller. It's suppose to be able to be
connected to a Mac or Windows computer and comes with software for each OS.
