The key fact is "five years old." The fact is, most SCSI devices until the
advent of the ASPI standard were not really designed to be SCSI in the
chainable sense we think of now. They were designed to be run from a card
specifically designed to run the device and with a driver that spoke directly
to the board. No chaining was possible unless it was precisely the same device.
The ASPI standard, which requires some chip support as "hooks" in the
device, is used by a ton of devices now and CorelSCSI has led the way to a true
SCSI interface–but it can't be responsible for the mistakes of third party
makers in not joining the club.
If a device is not ASPI compliant it can't be run by an ASPI manager any
more than if it were an IDE device. Period.
MASTER.TXT and PROLIS.TXT here in LIB3 list all the devices CorelSCSI
certifies that it supports.
