These priorities are purely a matter for AmigaOS, and do not apply to Linux.

A proper test machine would be an A3000 or A4000 (or T variant),
equipped with a Zorro II expansion card that contains Zorro II RAM
(e.g. a combined SCSI/memory expansion card).

This does not apply to BigRamPlus, which is a Zorro III memory expansion.

Thanks!
