Option Problems Action
An IBM option that
was just installed does
not work.
Verify that:
1. The option is designed for your computer.
2. You followed the installation instructions supplied with the
option and in Installing Options in Your Personal Computer.
3. All option files (if required) are installed correctly. See
“Installing Files from Option Diskettes” on page 97 for
information about installing option files.
4. You have not loosened any other installed options or cables.
5. If the option is an adapter, you have provided enough
hardware resources for the adapter to function correctly. Refer
to the documentation that comes with the adapter (as well as
the documentation for any other installed adapters) to
determine the resources required for each adapter.
6. You updated the configuration information in the
Configuration/Setup Utility program, if necessary, and have
no conflicts.
If the problem persists, run the diagnostic programs. (See
“Diagnostic Programs” on page 96 for information about
diagnostic programs provided with your computer.)
If the problem cannot be isolated and corrected, have the computer
and the option serviced.
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.
