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 f
rom 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 fil
e
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.
