EMM386.EXE Dynamic Memory Allocation |
The information in this article applies to:
-
Microsoft MS-DOS operating system version 6.0
SUMMARY
EMM386.EXE version 4.45, which ships with MS-DOS 6.0, dynamically
allocates and releases memory that conforms to the Extended Memory
Specification (XMS), the Expanded Memory Specification (EMS), or the
Virtual Control Program Interface (VCPI) specification. For example,
if a program releases a certain amount of EMS memory, other programs
that need XMS memory can request and receive additional XMS memory
from the released EMS memory. In other words, EMM386.EXE can provide
extended or expanded memory as needed by adjusting the EMS memory
pool.
MORE INFORMATION
You can limit this feature by using the maximum and minimum memory
parameters of EMM386.EXE. For example, if you want to give EMM386.EXE
2 megabytes of memory and keep it from dynamically allocating that
memory, use the following EMM386.EXE DEVICE line:
device=c:\dos\emm386.exe 2048 min=2048 ram
NOTE: This feature is application dependent. If an application does
not release allocated XMS or EMS memory, EMM386.EXE cannot give that
memory to other applications.
