Starting an Application Program Any time you see the MS-DOS command prompt (for example, A : \ > or C : \ >), you can start using an application program. Just log onto the drive and directory containing your application program files (if necessary) and type the name of the program's executable file. (See the documentation for your application program if you are not sure what to type.) When you press Enter, MS-DOS runs the application program. When you exit the program, the MS-DOS command prompt reappears. Be sure to exit the application program properly and return to the command prompt before turning off your computer. Using Memory Beyond 640KB Your Equity LT-386SX comes with at least 2MB of random access memory (RAM). MS-DOS and your application programs that run under MS-DOS use the first 640KB of memory. By converting the extended memory above 1MB to expanded memory, you may use this memory for certain application programs (for example, Lotus 1-2-3) that support the Lotus/ Intel/Microsoft Expanded Memory Specification (LIM EMS). To use expanded memory, you must copy the file EMM386.SYS from your MS-DOS Shell diskette to the root directory of the hard disk. Then modify the file CONFIG.SYS, which is stored in the root directory of the hard drive or the diskette from which you load MS-DOS. Using MS-DOS With Your Computer 3-31
