Slow Running
If you are not running from a boot
disk, you can try using SMARTDRV.SYS
or SMARTDRV.EXE loaded into your
CONFIG.SYS or AUTOEXEC.BAT. This
might speed up the game a bit.
If you are using MS-DOS 5.0, make
sure you have the following line in your
CONFIG.SYS file:
devicehigh=c:\dos\smartdrv.sys
If you are using MS-DOS 6.0 or 6.2,
make sure the following line is in your
AUTOEXEC.BAT file:
loadhigh c:\dos\smartdrv.exe
However, you might need to remove
this line if memory problems occur.
Q. Can I run my game through
Windows?
No. This is not recommended; it is
likely that you will not have
sufficient memory to do so.
Q. Does this game run with DR DOS,
Novell DOS 7 or OS/2?
Success is not guaranteed. Micro-
Prose games are currently designed
to run with MS-DOS 5.0 or any
100% compatible DOS.
Q. What is base memory?
This is the original 1MB (1024K) in
your machine. It is divided into
conventional memory (640K), where
MS-DOS and all PC programs load,
and upper memory (384K), where
system programs reside.
In MS-DOS 5.0, the bulk of the
operating system and associated
drivers (such as the mouse driver)
are normally loaded into upper
memory. Other drivers held in the
area of conventional memory will
reduce your 640K available for
the program.
It is important to have as much free
conventional memory as possible.
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
PC compatibles more memory to
run programs. It has been around
longer than XMS, so many older
programs take advantage of it. The
DOS command EMM386.EXE can
be used to turn XMS into EMS and
should be in your CONFIG.SYS.
Remember that hard drive space is
also measured in megabytes (MB).
Don’t confuse this with memory—
the two are completely different!
Memory Managers
If the program is occasionally freezing
or crashing to DOS, the game might have
a conflict with your current memory
manager. MicroProse recommends only
the drivers that come with MS-DOS (i.e.,
HIMEM.SYS and EMM386.EXE). Try
using the memory managers that come
with MS-DOS 5.0, Windows 3.1, MS-
DOS 6.0 or MS-DOS 6.2, in that order.
