Option Problems Action
An IBM option that
was just installed does
not work. Verify that:
1. The option is designed for the computer.
2. You followed the installation instructions supplied with the option. See “Installing Files from Option
Diskettes” on page 62 for information about installing option files.
3. The option is installed correctly.
4. You have not loosened any other installed options or cables.
5. You updated the configuration information in the Configuration/Setup Utility program. Whenever
memory or an option is changed, you must update the configuration.
If you are using an expanded- or enhanced-memory manager, such as the DOS expanded memory
specification (EMS) device driver, refer to “Memory” in Understanding Your Personal Computer.
Note: The Plug and Play feature uses memory addresses ED00h to EDFFh. If you use a memory-manager
program or install an ISA legacy adapter, make sure that they do not use addresses within this address
range.
If all of the above items are correct, start QAPlus/WIN-WIN or QAPlus/PRO. If the test programs find no
problem, have the computer 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 comes with its own test instructions, use those instructions to test the option.
If the items above are correct and the test programs found no problem, have the computer and option
serviced.
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 recurs, have the computer serviced.
