About Memory Managers
A memory manager is a software program that manages the use of memory in your
computer. If your computer has any expanded memory (EMS) or extended memory
(XMS) installed, you may be using some sort of memory manager.
In certain configurations, some memory managers may conflict with the following DH-
485 and DH+ network interface cards.

This section describes how to avoid these conflicts.
386MAX.SYS
386MAX.SYS is a memory manager produced by Qualitas, Inc.
There is an easy method to avoiding 386MAX conflicts with the interface cards.
386MAX is shipped with a program called MAXIMIZE.EXE. This program examines
your computer and makes certain that it won’t create memory conflicts with your
existing hardware. If you use MAXIMIZE.EXE to configure 386MAX, you should
have no conflicts with your interface. See the
386MAX User’s Guide
for more details.
QEMM.SYS
QEMM.SYS is a memory manager produced by Quarterdeck, Inc.
