Using Extended Memory
APS requires a minimum of 3 Mbytes of extended memory (XMS). To use
extended (XMS) memory, add the following command to your CONFIG.SYS file:
Type: DEVICE=HIMEM.SYS
If the file HIMEM.SYS is not located in your root directory (C:\), you must specify
the directory path to the file so DOS can locate the file (for example, DEVICE =
C:\DOS\HIMEM.SYS).
If you use HIMEM.SYS, we strongly recommend that you increase the number of
available XMS handles (NUMHANDLES) to 128. To do this add the following line
to your CONFIG.SYS file.
DEVICE=C:\DOS\HIMEM.SYS /NUMHANDLES=128
After you enter this command and save the modified CONFIG.SYS file, restart your
computer for the changes to take effect.
For more information about installing the extended memory manager, refer to the
ReadMe file included with this software. This file is located in the directory in
which the APS executable resides.
Note Be sure to add the following line to your AUTOEXEC.BAT:
C:\DOS\SHARE.EXE .
Using Expanded Memory
Use of expanded memory decreases APS performance; therefore, it is not
recommended. If you still choose to use expanded memory, follow the EMS 4.0 and
VCPI specifications so that APS can use the expanded memory successfully (for
example, DEVICE = C: \DOS\EMM386.EXE).
Determine if you can use expanded memory by referring to the chart on page 1–3.
If you use a memory manager that is not 100% compatible, your computer may lock
up when you attempt to run APS. Contact your local computer software vendor to
determine what requirements your memory manager meets.
