Norton Utilities Version. 6.01 (NCACHE) --------------------------------------- Some versions of NCACHE may prevent you from setting up or starting Windows 3.1. When Windows is running in standard mode, your system may fail, especially if NCACHE is set up as an EMS cache. Setting up NCACHE as an EMS cache is not recommended. Setting up NCACHE as an XMS cache may solve the problem. You may also encounter additional problems using NCACHE. New versions may correct these problems. For an updated version of NCACHE, contact Symantec Corporation. In the meantime, you can use SMARTDrive, which is provided with Windows 3.1. .
