Using Expanded Memory Beyond 640KBThe Equity 386SX PLUS comes with either 1MB or 2MB of random access memory. MS-DOS and your application programs that run under MS-DOS use the first 640KB of memory. You can use the memory above 640KB as extended memory, or you can use it as expanded memory, as described below.
Expanded memory can be used by certain application programs (such as Lotus 1-2-3) that support the Lotus/Intel/Microsoft Expanded Memory Specification (LIM 4.0 EMS). To take advantage of expanded memory, you need to use a memory manager to convert the computer’s extended memory to expanded memory.
Your dealer may have given you a memory management software package when you bought your Equity 386SX PLUS. If so, you can use this memory manager with either version of MS-DOS. Just follow the instructions included with the package.
If you are using version 4.01 of MS-DOS and you did not receive a memory manager, you can use the MS-DOS program EMM386.SYS to convert your extended memory to expanded memory. This utility is included with your version of MS-DOS. See your MS-DOS Reference Manual for instructions on using EMM386.SYS.
If you are using version 3.3 of MS-DOS and you did not receive a memory manager with your system, ask your authorized Epson dealer which expanded memory manager program you should use.
