Using the Adaptec SCSI Card 39320D and SCSI Devices
transfer rate of the LVD SCSI devices will drop down to
non-LVD SCSI performance levels of up to 40 MB/sec.
■ Internal LVD SCSI devices come from the factory with
termination disabled and cannot be changed. Proper
termination is provided by the terminator at the end of the
internal LVD SCSI cable.
Using SCSI Devices
If you connect SCSI devices (such as scanners, tape drives, zip
drives, etc.) to the Adaptec SCSI Card 39320D, you must install the
device manufacturer’s proprietary software drivers. See your
device’s documentation for details.
Combining SCSI and Non-SCSI Devices
You can install the Adaptec SCSI Card 39320D in a computer that
already has a non-SCSI controller, such as an ATA controller.
However, you cannot cross-connect the disk drives and other
devices: SCSI devices must be connected to the Adaptec SCSI Card
39320D, EIDE devices must be connected to the ATA controller,
and so on.
When you install the Adaptec SCSI Card 39320D and SCSI disk
drives in a computer that boots from a non-SCSI disk drive, the
computer will continue to boot from the non-SCSI disk drive
unless you change the computer’s CMOS configuration. You do
not need to change the configuration if you just want to use the
SCSI drives for additional file storage space.
