6. Attach the SCSI cable to the host adapter and to the last device. Do not forget the device’s power
connector.
7. Power ON the PC and verify that the host adapter recognizes the SCSI device.
8. If the SCSI device is recognized, power OFF the PC and install the next device. Verify recognition
for the next device and then install. From this point on, the system should be up and running.
9. If you performed a BIOS uninstall procedure, or if the host adapter has no BIOS, the system will
note recognize the devices until the drivers are installed.
8.2.2 Termination Configuration
When
configuring termination, the basic rule to remember is termination is required at both ends of
the SCSI chain.
•
To install a new device as the last device on one of the sides of the complete cable, you must
enable termination on the device.
•
When replacing another device that was previously at the end of the cable and is now installed on
another connector on the bus, you must disable termination on the device.
•
When installing an external SCSI device in a system that has only internal devices, you must
disable the host adapter’s termination using one of the following methods:
•
Using software (as with the newer Adaptec).
•
By removing the terminator packs (typically three) near the host adapter’s SCSI connector.
•
By setting a jumper on the host adapter.
The situation is the same if you previously had only external devices.
8.2.3 SCSI ID Configuration
When configuring the SCSI ID, first locate a free SCSI ID. The most effective method is to look at
the host adapter boot-up message and check for free IDs.

In this example, ID
2
,
5
and
6
are free for new devices. ID
7
cannot be used, as this is the host
adapter. The FFD uses DIP switches to set the ID in a 4-2-1 configuration. The sum of the switch
values determines the ID. For example, if you want a hard disk with ID
0
, set all three switches to
OFF.
