Option problems Action
An IBM option that
previously worked
does not work now. Verify that all of the option hardware and cable connections are
secure.
If the option comes with its own test instructions, use those
instructions to test the option.
If the failing option is a SCSI option, verify that:
1. The cables for all external SCSI options are connected correctly.
2. The last option in each SCSI chain, or the end of the SCSI cable, is
terminated correctly.
3. All external SCSI options are turned on. External SCSI options
must be turned on before the system is turned on.
For more information, see your SCSI documentation.
If the problem cannot be isolated and corrected, have the computer
and option serviced.

1. Each port is assigned a unique address.
2. The parallel-port adapter, if you added one, is properly installed

If the problem cannot be isolated and corrected, have the computer
serviced.
