Memory Problems The amount of memory displayed is less than the amount of memory installed. Not enough memory message is displayed. Action The amount of available memory shown might be somewhat less than expected because of basic input/output system (BIOS) shadowing in random access memory (RAM). Verify that: 1. You have installed the correct type of DIMMs for your computer. Refer to Installing Options in Your Personal Computer for instructions on adding DIMMs. 2. The DIMMs are properly installed and securely connected. 3. If you added or removed memory, you saved the new configuration in the Configuration/Setup Utility program. See the Important text box on page 34 for instructions on saving the configuration. If the problem persists, run the memory test from the diagnostic program that comes with your computer. (See "Diagnostic Programs" on page 95 for further information.) The system might have detected a bad DIMM and automatically reallocated memory to enable you to continue to operate. If the problem cannot be isolated and corrected, have the computer serviced. Verify that terminate-and-stay-resident programs (TSRs) are not taking up memory. (See "Managing TSR Programs (DOS or Microsoft Windows 3.1x)" on page 96.) Chapter 6. Solving Problems 91
