Option Problems An IBM option that was just installed does not work. An IBM option that previously worked does not work now. Action 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 139 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. For instructions, refer to Chapter 5, "Using the Configuration/Setup Utility program" on page 61. If the problem persists, run the diagnostic programs. (See "Diagnostic programs" on page 136 for information about diagnostic programs provided with your computer.) If the problem cannot be isolated and corrected, have the computer and the option serviced. 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. Chapter 7. Solving problems 133
