Using Expanded Memory Beyond 1MB
The Equity 286 PLUS comes with 1MB of random access memory. MS-DOS and your application programs that run under MS-DOS use the first 640KB of memory. If you have installed additional memory (above 1MB) in your computer, you can use it as extended memory or expanded memory, as described below.
Expanded memory is required by certain programs (such as Lotus l-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. Follow these steps:
1.Run the SETUP program to allocate the amount of memory you want to use as expanded memory. See “EMS Size” in Chapter 2 for instructions.
2.Copy the file EMM286.SYS from your Reference diskette to the root directory of your hard disk (or the Startup diskette from which you load MS-DOS). You may put the EMM286.SYS file in another directory as long as you include the appropriate pathname on the DEVICE = command line in the CONFIG.SYS file. See the instructions below.
3.Add a command to the CONFIGSYS file to include the memory manager as a device driver, as described below.
