Memory Configuration:
* To run Microsoft Flight Simulator 5.1, you need a computer
with at least 500 kilobytes (K) of free conventional memory. If your
computer does not have an expanded memory manager (EMM), you
need 560K of free conventional memory. Flight Simulator displays a
message if your computer has insufficient conventional memory, and
you cannot run the program. Please refer to the "Troubleshooting
Guide for Setup" in Chapter 24 of the Flight Simulator Pilot's
Handbook for tips on optimizing your system performance.
* You can significantly enhance Flight Simulator's performance
if you configure your computer for expanded memory. Please
refer to the "Troubleshooting Guide for Setup" in Chapter 24
of the Flight Simulator Pilot's Handbook or to your MS-DOS
manual for instructions on how to configure your computer for
expanded memory.
* If you have no extended or expanded memory, or encounter out
of memory errors when running Flight Simulator, you will get
better performance if you turn off the sound option. To do
this, choose Preferences from the Options menu, and then
choose the Sound button. In the Sound Preferences dialog box,
choose No Sound Device from the Sound Board list. This will
save additional conventional memory and allow more features
to run.
* If your machine has only 4 megabytes (MB) of memory,
Flight Simulator will run better if you use the RAM memory
parameter (see MS-DOS help on EMM386.EXE) with no EMS
limiter syntax used in the emm386 line in CONFIG.SYS for
MS-DOS version 6.0 or later. If you are running MS-DOS
version 5.0, you will have better memory and system
performance if you upgrade to MS-DOS version 6.0 or later.
For example, the RAM memory parameter is as follows:
DEVICE=C:\DOS\EMM386.EXE RAM H=255 D=64
Your actual line may have slightly different arguments, but
the important thing is the presence of the RAM argument.
H=255 is the number of EMS handles, and D=64 is the number
of direct memory access buffers. The values shown are best for
Flight Simulator.
