==================================================================
IF YOU RUN ANY PROGRAM UNDER WINDOWS' 95, MAKE SURE YOU TURN OFF
THE SCREEN SAVER OPTION. You also need 16Mb of RAM, to be on the
safe side.
MAKE SURE YOUR CONFIG.SYS HAS THIS LINE:
SHELL=C:\DOS\COMMAND.COM C:\DOS /P /E:345
You PC may not be able to lauch or recognize small batch file
without the above command line.
1. Problem due to insufficient RAM to load program.
Symptoms: "Not enough memory to load program"
Suggestions:
a. Install more memory
b. Run MemMaker (from MS-DOS 6.x) to optimize your memory setting
or use any memory manager to reconfigure your system.
c. Remove as many as non-essential drivers and TSR programs.
d. If running Windows programs, close as many Windows as possible.
2. Problems due to programs try writing to the CDROM.
(CD is a READ-ONLY device, cannot be written to)
Correction: Some programs need to update score or data files when you
exit the program. Your computer may hang or give an error message when
the program tries writing to the CDROM. Either ignore the error and
reset the system OR copy program to hard drive.
3. Certain programs or games, especially the graphics-intensive ones,
tends to take a long time to load program into screen, WHY?
How to speed it up?
Answer: The access time of most double speed CD-ROM drive is about
200- 300ms (compare to hard drives' 10- 30ms), so it is a lot SLOWER
when loading big programs. You may want to get a quad-speed CD-ROM
or install cache program that will speed up CD-ROM drive. Note that
not every cache program speeds up CDROM access time.
4. Some games or program run fine on its existing settings,
it freezes, hangs, or give a disk error or I/O error message when
I try to change its setting.
Answer: Since CD is a READ-ONLY media, game settings that have been
written onto it cannot be changed. You get the above symptoms if you
try to change it. Either run the program as is OR copy it onto your
hard disk, then you can change its setting without problem.
5. Program still freezes or gives "I/O error" or "Access Denied"
messages even after I have copied program from CD-ROM to my
hard disk.
Answer: The file attribute of the programs is set to "R" (read-only)
when they are copied to the CD-ROM. You have copied these files
with the "R" attribute. If you don't remove the "R" attribute, your
PC will not be able to write or update certain data files and give
you I/O and access error messages. Run the following command
to remove the "R" attribute:
ATTRIB *.* -R /S
6. Program does not run properly even though I did what are
suggested in #5.
Answer: Some programs may need an "actual install" (install
under certain designated directory name or create sub-directories
in a certain order). Try looking for any file with names like
INSTALL.EXE, INSTALL.BAT, or INST???.exe; run the file and
do an installation to ANOTHER subdirectory. Also read any
.DOC or .TXT file for instructions.
7. How to figure out the playing commands?
Answer: There are two ways:
a. Most programs has a help key, "F1" is the most popular one.
The help key will give you command summary and other essential info.
So look for the help key on your screen. If no help key is found,
see if you can found a cursor on screen. You may control the cursor
with arrow keys or mouse. Then try out different buttons or choices.
b. Exit the program and manually log into the subdirectory in which
the game resides. Look for any file with .DOC or .TXT extension and
read it with DOS's EDIT or the LIST, SEE utility (copies in the NOTES
sub-directory). Most games comes with instructions in the form of
README file, or README.TXT, or README.DOC, or MANUAL.TXT, or
MANUAL.DOC. You can print out the instruction with EDIT (from DOS),
or SEE or LIST or your favorite word processor.
For Windows programs, look for the files with .WRI extension, you
can read it by simply "clicking" on the file.
8. How to EXIT or get out of certain games and demo?
Answer: Some software authors are too lazy to write the exit routine.
Most common commands to get out of a program are:
ESC F10
CTRL-X; CTRL-Q; CTRL-U; CTRL-Break; CTRL-ESC; CTRL-PRINT SCREEN
ALT-X; ALT-Q; ALT-ESC
F10 CTRL-ALT-DEL
FOR WINDOWS: ATL-F4
When everything fails, use CTRL-ALT-DEL keys. DON'T use reset button
when running WINDOWS, you may damage the hard disk.
9. Some games run fine under certain DOS version like DOS 5.0 and do
not run under 6.0 or later.
Suggestion: Make sure you have this line "DEVICE=C:\DOS\SETVER.EXE"
in your CONFIG.SYS. Then run SETVER to set the game program to the
DOS version that it will operate. For example, if GAME.EXE will run
under DOS 5 and you are using DOS 6, run this command:
C:>SETVER GAME.EXE 5.0
You need to reboot system for the changes to be effective.
Refer to DOS manual on SETVER if you have any questions.
10. Problem due to insufficient video memory and incorrect video
card driver. (Some games require you to choose a video driver,
some high-resolution games need more than 512k video RAM)
Symptoms: There's no picture on screen, but the hard disk sounds like
it is retrieving something.
Strange colors in pictures.
Correction: If you have another VGA card, try it to see if problem
persists. Find a VGA card with more memory. Choose a different video
driver to see if problem goes away.
11. Problem due to pointing devices such as mouse and joystick
(Some games won't run without a mouse)
Correction: Load the mouse driver and install a mouse. If the mouse
is jumpy or erratic, check if the mouse driver load is the correct one.
Also check if serial port and/or mouse is defective or not.
12. Problems due to incorrect sound drivers, program crashes or
refuses to run.
Correction: If the program assumes you have a sound card installed
and you have none, run the setup or install utility of the program,
select PC speaker or none (no sound card). Then the program won't
look for a sound card when running.
If you have a sound card and the program reports no sound card or
incorrect driver, re-install your sound card driver that comes with
the card; check if problem goes away; if not; run the setup or install
utility of the program.
13. Problems due to previous program has initialized a system
setting and "forget" to re-initialize the system when exiting
down the programs.
Symptoms: Program A will run ONLY you have restart the computer;
or Program A won't run if Program B is run before it.
Correction: When everything else fail to fix the problem, restart
the computer and try again
14. Some games runs fine on its existing settings, it freezes, hangs,
or give a disk error or I/O error message when I try to change its
setting.
Answer: Since CD is a READ-ONLY media, game settings that have been
written onto it cannot be changed. You get the above symptoms if you
try to change it. Either play the games as is OR copy it onto your
hard disk, then you can change its setting without problem.
15. I get "PATH NOT FOUND" error after runing the DESCENT game.
Answer: Descent re-initialize the path statement in the system
in a way the default setting has changed. Simply exit installation
menu and type GO and enter again.
MOST OF THE PROBLEMS THAT YOU RUN INTO WILL GO AWAY WHEN YOU COPY
THE PROGRAM ONTO THE HARD DRIVE, IF NOT, ALSO RUN "SETUP", OR
"CONFIG" TYPE PROGRAM/ UTILITY TO CHANGE THE DEFAULT SETTING TO
THE ONE THAT MATCH YOUR SYSTEM.
If copying the game from CD-ROM to hard disk does not fix the
problem, copy the ZIP files fo the game to hard disk, uncompress
it using PKUNZIP or UNZIP, re-run INSTALL, CONFIG, or SETUP.
Then the game should run fine. Problems of this sort is caused
by file names characters not allowed for ISO 9660 standard for
CD-ROM.
====================================================================
WINDOWS SPECIFIC PROBLEMS
====================================================================
The Windows Operating System is more complicated than DOS. It
operates on top of MS-DOS and also has more problems than DOS.
So many factors can affect the operating of your programs.
The following is only a partial lists:
- hardware problems: compatibility issues
- software problems: driver problems, bugs
- address conflicts: IRQ conflicts, memory address conflicts
Microsoft has published a WINDOWS RESOURCES KIT ($20), which is
very useful in troubleshooting your WINDOWS problems. Also there
is a book called "1-800-WINDOWS HELP" that is pretty good.
Most Windows problems are memory-address related. If you get
"GENERAL PROTECT FAULT" or whatever memory error messages, try
unloading as many programs as possible and re-run your program,
if it still does not work, exit WINDOWS, reboot system, and reload
program; if it still does not work, check your CONFIG.SYS and
remove or rearrange the order of loading device drivers, reboot,
reload program.
GP Errors are normally caused by incompatible or outdated
device drivers.
Many problems occur after you run program A and try to load program B
(program B works only when you do a fresh reboot). Some lazy
programmmers do not follow the written procedures in unloading
their programs, thus causing problems.
1. Problem due to incorrect Windows video driver.
Symptoms: Picture looks like missing some colors or shows only 16 colors.
Correction: Exit Windows. Log into Windows subdirectory and run SETUP.
Move cursor bar to video driver and re-install video driver
with the driver disks that come with your video card. Make
sure choose the one with 256 colors.
2. Certain Parts of the image are too bright on too dark.
Correction: Due to the hardware differences between different
monitors and video cards, you may need to adjust the
brightness and intensity of your monitor to get the
best images.
3. Problem due to insufficient video memory and incorrect video card driver
Symptoms: There's no picture on screen, but the hard disk sounds like
it is retrieving something.
Strange colors in pictures
Correction: If you have another VGA card, try it to see if problem persists.
Find a VGA card with more memory. Choose a different video driver to see
if problem goes away.
4. WINDOWS does not boot up from the default menu in the CD-ROM.
Correction: WINDOWS directory is not in the DOS path. Simply add
WINDOWS in your DOS path in your AUTOEXEC.BAT.
5. I get "SHARING VIOLATION" when runing language Viewer.
CORRECTION: DOS version earlier than 6.22 will give you this error
message. Simpy add SHARE in your AUTOEXEC.BAT:
C:\DOS\SHARE
6. I see garbage or nothing on screen when reading some .DOC or .TXT file.
CORRECTION: 1. Some foreign language file will be shown as garbage
if you did not load the operating system in that
foreign language in your computer or if you don't
load the foreign fonts before your read the foreign
language files.
2. You may not have the right file viewer because
Microsoft Word documents also has .DOC extension.
Use Microsoft Word or WORD VIEWER (enclosed in
the WORDVIEW directory). Simply click on the
WORDVIEW.EXE file and run it directly from the
CD-ROM, no installation is need.
7. I get "I/O error" or "access denied" messages when I run the
program from CD-ROM.
Corrections: Some programs create some temporary files or
write to whichever directory on which they reside. Since CD-ROM
is a REASD-ONLY media (means your computer can't write on it),
you will get the above error message when writing on it.
Simply copy the files to your hard disk and run from there.
If .ZIP files are available in the directory, click on it twice
and unzip the original files to your hard disk. If otherwise,
run any "INSTALL.EXE" file in the directory if available;
if not, simply copy all the files onto your hard disk, then
log into the new directory and run the following command:
ATTRIB *.* -R (ENTER)
Please run this command under DOS. Files originated from CD-ROM
are all marked READ-ONLY, so that your computer will not write
on it and damage your CD-ROM drive. When you copy this files
into your hard drive, your computer does NOT remove the READ-ONLY
attribute from the files. You will still get "Path/access denied"
message if you do not manually remove it.
8. The program gives an error messages saying some files like
VBRUNx00.DLL or some DLL files is missing.
CORRECTION: We have included a collection of common DLL files
in the DLL directory. Simply copy the one that you need into
that program directory.
