Troubleshooting
Option Problems
Action
An IBM option that was
just installed does not
work.
Verify that:
1. The option is designed for the system.
2. The Reference Diskette was updated with the
information on the Option Diskette, if one was
provided. (See “Using the System Diskettes” on
page 164.)
3. You followed the installation instructions supplied
with the option.
4. The option is installed correctly.
5. You have not loosened any other installed options
or cables.
6. The configuration information has been updated.
To update the configuration information, run the
Automatic Configuration
program.
If you are using an expanded- or enhanced-memory
manager, such as the DOS Expanded Memory
Specification (EMS) driver, go to “Configuration
Conflicts” on page 372.
If all of the above items are correct, start the system
programs and run the Test the Computer program. If
the test programs find no problem, have the system
and the option serviced.
An IBM option that used
to work does not work
now.
Verify that all of the option hardware and cable
connections are secure.
If the option came 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. (See “SCSI
Drives” on page 218 for more information on SCSI
terminators.)
3. All external SCSI options are turned on. External
SCSI options must be turned on before the system
is turned on.
If the items above are correct and the test programs
find no problem, have the system and option
serviced.
