The A4000t scsi device inside morphos "should" work
but it wasn't tested for a long time...
I assume it's only a HW detection problem and not
a problem of the device itself.

Please boot with your rom kickstart, so remove this
<nokickstart> startup parameter.

please check with <c:devlist> if scsi.device is
there.

if not, please do a <c:modlist> to check if your
kickstart has a workbench.library, as the MorphOS
A4000T detection only works through checking
for a not existing workbench.library in the rom.

Further informations can be retrieved through
EDebugFlags="Init InitResident" and capturing
the output with ramdebug or serial.
