TECHNICAL SUPPLEMENT
Copy Protection
SubWar 2050 has no disk copy protection. However, the program asks you a
manual-related question. Use the manual to answer the question. MicroProse
regrets that continuing casual and organised software piracy requires that this
minimal form of copy protection is retained.
Installation
An installation program is included on the SubWar 2050 Disk A.
Insert Disk A into your floppy drive (drive A or B) and designate that drive (by
typing “A: [Return]” or “B: [Return]”).
When the new prompt appears, type “INSTALL [Return]”
Please follow the on-screen text which appears.
The default (pre-set) installation routine places SubWar 2050 in a directory named
C:\MPS\SUBWAR
Loading Instructions
Switch on your machine and wait until the C:\> prompt appears.
Type “CD MPS\SUBWAR [Return]” and then type “SUBWAR [Return]” to run
the game.
Note: If you have installed SubWar 2050 to another directory, you must type “CD
[name of your directory]” first.
If the game fails to load, read the Problem Section of this Technical Supplement.

TECHNICAL SUPPLEMENT
Sound
SubWar 2050 supports the PC internal speaker, AdLib compatible cards,
SoundBlaster compatible cards and the Roland LAPC-1 card.
Operating Difficulties and Loading Problems
Q. Why can’t I install the game to my hard disk?
1. You must check all system requirements, especially any mention of hard disk
space required, listed in this Technical Supplement.
2. If you still have a problem, you should make copies of the original disks and use
the duplicates in place of the originals; sometimes you’ll get a read error due to a
difference in head alignment.
3. If the game still doesn’t work, make sure you are not running a compression
utility program on your hard disk.
4. Finally, try installing the game on another machine to see if the problem recurs.
Q. How do I copy disks?
From the C:\> prompt, use the DOS command DISKCOPY A: A: [Return]. Follow
the on-screen prompts.
Q. Why won’t my game load?
You must have 611,000 bytes (596K) of Conventional Memory and 10K UMB
(Upper Memory Block).
To check that you have allocated an upper memory block, look for the line
DOS=UMB (MS-DOS 6) or DOS=HIGH,UMB (MS-DOS 5) in your PC's
CONFIG.SYS file.
Slow Running
If you are not running from a boot disk, please ensure that you have
SMARTDRV.SYS or SMARTDRV.EXE loaded into your CONFIG.SYS or
AUTOEXEC.BAT.

TECHNICAL SUPPLEMENT
Conventional Memory
To check how much Conventional Memory is available, type MEM/C from the C:\>
prompt and press the Return key. Look for the Largest Executable Program
details. If there is not enough Conventional Memory, you may need a Boot Disk.
Q. What is a Boot Disk?
This is a Start Up disk for your computer which contains alternative start up files
to those on your hard disk. The Boot Disk will allow you more Conventional
Memory.
Making a Boot Disk
Instructions for making an MS-DOS Boot Disk (also known as a System Disk) will
be found in your Microsoft manual.
Using a Boot Disk
Insert the Boot Disk into your floppy disk drive A and then switch on the
computer. You should leave the disk in the floppy drive during play.
Q. Can I run my game through Windows?
No, this is not recommended, unless specifically mentioned in the system
requirements.
Q. Does my game run with DR DOS?
Success is not guaranteed. MicroProse games are currently designed to run with
MS-DOS 5.0 or 100% compatible DOS.

TECHNICAL SUPPLEMENT
Q. What is Base Memory?
This is the original 1Mb (1024K) in your machine. It is divided up into
Conventional Memory (640K), where MS-DOS and all PC programs load and
Upper Memory (384K), where system drivers (such as the mouse driver) reside.
In MS-DOS 5.0 the bulk of the operating system and associated drivers are
normally loaded into Upper Memory. Other drivers held in the area of
Conventional Memory will reduce your 640K available for the program.
Q. What is Extended Memory (XMS)?
Further memory, beyond the 1Mb of Base Memory on your PC is called Extended
Memory. XMS can be used to free more Conventional Memory so that bigger games
can be run. XMS can also be used to simulate Expanded Memory.
Q. What is Expanded Memory (EMS)?
EMS was originally designed to give the PC more memory to run programs. It has
been around far longer than XMS so most programs take advantage of it. Most
MicroProse games take advantage of EMS. The DOS command EMM386.EXE can
be used to turn XMS into EMS and should be in your CONFIG.SYS.
Remember that hard disk space is also measured in Megabytes (Mb). Don’t confuse
this with memory - the two are completely different!
