Setting up the soundcard to work correctly is one of the most difficult steps in
configuring your game.
This document assumes your sound card has been working properly with Windows 95 and 98
based games and you have the latest Drivers and Software installed or handy. This document
is offered as a step by step guide. It does not cover any other versions of Windows (It may
be useful for WinME users). The Document is tailored for Sound Blaster Cards (the dos
standard) However the information below will prove useful for others.
This document was developed based on the Duke3D/Apogee Sound System and should prove to
be compatible with other BUILD Games.
Further development maybe required for some BUILD Games.
- Locate your Autoexec.bat file. It's in your root directory.
- Open it with text editor and locate your sound cards setup line:
Typical examples would be something like this:
- SET SNDSCAPE=C:\WINDOWS
- SET BLASTER=A220 I5 D1 T2
- C:\Program Files\CREATIVE\SBLIVE\DOSDRV\sbeset -A240 -I5 -D1 -H5 (H is the
- SET BLASTER=A220 I5 D1 H5 P330 T6
- Copy the SET BLASTER line down on paper.
In Control Panel:
- Open your Windows Control panel and click on the System Icon.
- Find the line "Sound,video and game controllers" and click on your Sound card.
If you have more than one sound card device listed, you're looking for the one that's
labeled with ISA, DOS, or Legacy.
- Once you have the Driver open, locate the DOS settings and copy them down. ISA users
will only have one group of settings while PCI soundcards may have all or
features. Typically you're looking for something like these:
- Sound Blaster Pro Settings: Port 220 - IRQ 5 - DMA 1
- Sound Scape Settings: Base/MIDI Port 330 - MIDI IRQ 5 - Wave Port 534 - Wave IRQ 5 - DMA
- MPU-401 Settings: Port 330 - IRQ 5 - AdLib Settings - Port 338
- Copy the settings down on paper.
- If your sound card driver/software doesn't supply you with the above information, use
the Resource Tab
- Interrupt Request = IRQ
- Direct Memory Request = DMA
- Input/Output Range = Port (you will only need the first 4 digits to get the Base Port
- Input/Output Range (MPU-Midi Playback) = Port
- Typically your looking for something like this:
- Interrupt Request 5
- Direct Memory Request 1
- Input/Output Range 220
- Input/Output Range 330 - For Midi
- Input/Output Range 338
- Copy the settings down on paper
- Compare all the settings and make sure they match. If they don't match each other, you
may have to do some configuring, See ISA / Legacy Knowledge Section below for
- Wave IRQ and DMA settings are for SB emulation of your PCI Legacy Device.
- Note: If your systems motherboard has a built-in or on-board sound card, check to make
sure it's set up correctly in your BIOS. You usually need Legacy Sound on in order to use
it. If your using a separate audio card, rather than the onboardboard card. You may still
need to Turn on Legacy sound in your BIOS. But do it as a last resort to prevent unwanted
drivers from loading.
Check For EMM386.EXE
- Locate your Config.sys file. It's in your root directory.
- Open it with a text editior and locate the memory manager line.
- Typical example:
- This managers presence is required for your PCI DOS Driver. You can add NOEMS to the end
of the line to prevent Expanded memory from being used.( This can be set from your Windows
DOSBox shortcut, See: the RTCM Run In Windows Document)
Check For PCI Legacy DOS Mode Initialization:
PCI snd cards tend to modified Initialization there DOS drivers in different ways.
However they all modifie a important files. These include: "Exit to MSDOS.PIF" ,
AUTOEXEC.BAT , SYSTEM.INI , DOSSTART.BAT to intialize the card, the locations
are typicaly based on driver install options or forced options. But these methods ensure
your PCI card is intialized if you use an alternative method of reaching MS-DOS Mode, such
as a shortcut to an MS-DOS application like Duke3D.
Below we deal with a standard that's familiar with standards dealing with DOS Only
Games. In other words where trying not to deal with Windows highly sensitive files. Rather
we override them on a safer level. Follow the steps below to initialization your DOS
Drivers for PCI Cards.
Note: the DOSSTART.BAT File is in the \Windows folder
- Locate your Autoexec.bat file. It's in your root directory.
- Open it with a text editor and locate your snd cards setup line:
- Typical examples would be something like this:
- SET SNDSCAPE=C:\WINDOWS
- SET BLASTER=A220 I5 D1 T2
- LH C:\SBAPC64V\APINIT.COM
- LH C:\Program Files\CREATIVE\SBLIVE\DOSDRV\SBEINIT.COM
- LH C:\VIAUDIO\VIAUDIO.COM
- The three italic lines indicate two separate examples of what your looking for. Keep in
mind these are examples and probably will be different from yours. They are commands used
to initialize your PCI sound card to ensure you that your Sound Cards DOS Support is
operating (loaded) at Windows Startup. For use with a WinDOSBox and when you use START |
Shutdown | Restart in MS-DOS mode.
- If you Rather have the DOS Sound support active Only when opening a WinDOSBox and when
you use START | Shutdown | Restart in MS-DOS mode. Then make sure you remove the
Initialization command from your Autoexec.bat file. Now locate your dosstart.bat
file in your \Windows folder, and add your Initialization command there. So during a
Windows session the MS-DOS mode driver is inactive until MS-DOS mode is entered. This is
equivalent to switching the emulation off from your drivers control panel if yours has the
feature. Also if you where having some window problems as a result of the DOS Drivers
being loaded. Then this may elevate some of the problems (do not uninstall the emulation
files or software altogether, you need them for your BUILD game)
- These 'Drivers' can be loaded into High Memory if you have enough room, In most cases
this will require you NOT to use the NOEMS as noted above. Use LH like it is
presented in the last examples above.
- Note the order in which the lines above are. Make sure your SET BLASTER line is BEFORE
your PCI DOS Mode initialize command.
- If a similar line is not present then you need to read your Sound Cards Manual and
review the instructions on how to install its dos drivers and software (including updates)
before you continue.
- Make sure you reboot after making all the above changes.
Now we will apply the sound card configuration to Duke (Duke Setup.exe is located in
your duke game directory).
- Go to Sound Setup
- Choose Sound FX Card to match your brand. Typical is Sound Blaster. Setup will then try
to detect your cards settings.
- Change Address, you want this to match your cards Port number.
- If there's an option to Change Sound Card Type (model), choose the least demanding.
Typical is Sound Blaster or compatible. Newer cards may work with the SoundBlaster Pro
v2(new) setting. The SBLive! Card should use Sound Blaster 16 or AWE32
- Change Interrupt to match your cards IRQ number.
- Change 8-Bit DMA Channel to match your cards low 8-bit DMA number.
- Change 16-Bit DMA Channel to match your cards high 16-bit DMA number (if your card
supports it, see "collecting sound card settings" above)
- Now once your done click on the "Use these settings and continue" line.
- You will see several configure options, for now use these values.
- Number of voices, select 8
- Number of Channels, select Mono if your card supports it
- Mixing Rate, select 11khz
- Once you get back to the main Sound Setup menu, select test sound FX card.
Warning: System MAY crash or lock up. Use ALT+CTRL+DEL to close the setup.exe program.
Restart your computer.
- You should hear the test sounds.
- If the sound is crackling or crappy or simply won't play recheck your system's
configuration and recheck your settings in setup. Choosing a closer match or model of the
sound card may provided better performance.
- Once you get the sound to playback in a stable and clear manner. Go back and Select the
- Go back to the main Sound Setup menu, select test sound FX card.
- If the sounds play in the incorrect speaker according to the text on the screen. Select
Duke Nukem's setup: is very flexible. It will allow you two select General MIDI
music (Highest Quality Snd) and Sound Blaster digital audio. The SoundBlaster menu then
requires you to select what type or model of SoundBlaster you would like. A PCI Legacy
card should choose SoundBlaster Pro I as their first choice, pro II as their
your PCI card supports Soundcape (ENSONIQ), this should be your first choice before
considering a SoundBlaster or General Midi. Use what ever gives you the richest snd, no
cracking noise, or drop outs.
PCI Wavesets: MIDI Synthesizer Wavesets/Wavetable; The highest quality MIDI snd
your card can produced. Typical Wavesets are 2, 4, and 8MB. 4meg is ideal for hardware
wavetable replacement or substitution. Your BUILD game will use these wavesets. Locked or
Unlocked, Regardless if you have this option checked or unchecked in your soundcards
control panel. Your entire waveset is locked into memory for DOS Box and MS-DOS Mode if
your DOS sound drivers are loaded. Otherwise you may notice a delay during the games
startup sequence. It will have to wait for the Wavsets to load.
Sound Card Mixer: In DOS or MS-DOS Mode the Windows Mixer is not used. Your
sound cards DOS Mixer is independent. Note: Running Windows then shutting down to DOS-Mode
will not reset your DOS Mixer.
Windows DOS Emulation: PCI sound cards when in DOS emulation, Use a virtual
device (software) to emulate the resources that "old" ISA-based (aka
Legacy) soundcards used. When your PCI card is Legacy Emulation enabled in your
settings tab(The Legacy Device can be disabled from within in Windows if you have this
feature. ) The Legacy Device will appear in the Device Manager. Drivers: Always use
your sound cards Install wizard to handle any updates..etc...
Windows DOS Box: The recommended method for Installing and playing DOS games
with systems that use PCI snd cards is to open a MS-DOS virtual machine (DOS Box). You can
However Load Windows and then START | Shutdown | Restart in MS-DOS Mode if your system is
configured that way. See the "Check For PCI Legacy DOS Mode
Initialization" section above about dosstart.bat
Windows DOS Mode: Sometimes your game will beunable to run in a DOS Box. An
Incompatible with Windows may be one example. Most if not all BUILD Games CAN be Run at or
near 100% in Windows. A Windows98 DOS Box is more stable then the Windows95 DOS Box with
default settings. However Windows95 DOS Box can become of equal performance with the
default settings tweaked. Basicly your more likely not to have to tinker with a user
defined ms-dos shortcut with Win98.
Another common problem, your system might not have enough system resources to play the
game with Windows loaded. If this is the case use the mechanism called DOS Mode which
loads only the real-mode portions of the operating system.
Restart in MS-DOS Mode:
This is an alternative to using a WinDOSBox. DOS Mode runs outside of windows,
while technically your still in Windows.
- To enter the Windows DOS Mode, restart your computer in MS-DOS mode from the shutdown
- START | Shutdown | Restart in MS-DOS mode
When the computer is restarted into DOS from Windows a Program Information File (PIF)
named "Exit to DOS.PIF." is run. This PIF contains the information needed to
shutdown/unload most (not all) of Windows GUI properly and configure the system for MS-DOS
mode. The DOSSTART.BAT file is then executed to initialized any commands
MS-DOS mode to function. Then your system is placed in DOS Mode. Supporting normal DOS or
Legacy sound depending if your using a ISA or PCI card.

|PnP ISA and PnP PCI
||If you can't do ANYTHING else to
the resources you need. Placing the PnP sound card in the last slot on the motherboard
will usually allow your snd card to acquire the standard settings needed. Make sure to
reboot first after removing the card before you reinsert the card in a new slot.
This procedure is typically done if your systems/motherboard BIOS dose not provide options
to configure your settings. In the future, if you plan on upgrading your system and still
want to run DOS games. remember to place your card in the last slot.
Normally this is where
your ISA?PCI Controller will default to.

||This is actually a problem with v1.5 using
the command line switch /f4. This is not related to a sound setup error.
|Not responding on selected port.
||Try switching off stereo. On rare
occasions this may occur
What about these Popular ISA Resource Settings, what are
PCI Legacy Devices request the most popular resource settings when installed. These
resources would normally be available to the ISA bus.
The majority of the resources in a system can easily be reserved for the ISA bus because
all PCI devices in a system can share a single interrupt (IRQ steering, see "PCI
Steering below"). Only a few PCI devices, using distributed DMA, need a DMA channel
to be available. (DMA is only required for PCI cards when used in any mode of DOS)
My DOS Game ,,DOS Extender and IRQ problems ?
Some older dos extenders (Most Build Games use v1.97 dos extenders- newer) have problems
handling IRQ bus 10 events that occur in protected mode, this may crash the DOS extender.
(Note: This is not the PCI based IRQ, but rather the ISA or ISA mode IRQ; The Base
PCI-IRQ is for system/windows use). , So the ISA IRQ 10 should not be assigned, it should
be reserved else where. However BLOOD and shadow Warrior require an IRQ below 9.
Why should I leave open IRQ 5 ?
Reserve IRQ 5 for the ISA bus instead to allow your Legacy Device to acquire it. Use your
system BIOS setup to manual change the PCI ISA-IRQ. Using the BIOS setup is the preferred
method for manually setting up your PCI snd card, never use windows settings as you would
with a real ISA snd card, see PCI steering below ) IRQ 7 and 9 are also often used by
Legacy Devices and should be reserved for the ISA bus. Note: At least one interrupt (IRQ)
must be available to the PCI bus. PCI-IRQ 11 is a good interrupt to leave for the PCI bus.
Do I use DMA 1 or 3 ?
Some Legacy Devices use DMAs 1 and 3 for the ISA bus, this is a rare occasion. However if
you do need to change the DMA setting, again use your BIOS setup to manually change them.
SoundBlaster Live! may require a DMA of 3.
MY Game doesn't automatically detect my Sound Card, why ?
Older games, such as BUILD based games without the luxury of having a 32-bit Setup
Frontend (PaintBrawl Has WinFrontend) may have difficulty detecting your PCI card at
certain resource settings. Typically these games would expect an ISA to be at a fixed set
of popular ISA resources (or firmware) and would fail to load if those resources were not
detected. If you have a BUILD DOS game setup.exe and your systems has this problem , try
changing the Legacy Device configuration. If your sound card has problems detecting your
resources or behaves erratic, Disable your PCI steering to allow your BIOS to
automatically detect it, and not windows.
You can usually change these settings in the Windows Device
manager. These changes reflect in a DOS box and MS-DOS Mode.
PCI Steering, how to disable it:
- Right click My Computer and select Properties.
- Find PCI Bus and double click on it.
- Uncheck the checkbox labeled "Enable PCI Steering".
Newer PCI sound cards tend to crash most build games that use the Apogee Sound Engine,
if not all. This may occur in map sectors where the Echo (reverb) settings are switched on
Such as water, sewers, subways etc... ).
This error occurs on such cards as SoundBlaster Live, Creative Labs SB or Ensoniq PCI
Audio Cards, and cards with the ESxxxx(Software) and ESS(hardware FM synthesis (ESFM))
chip sets. This is a result of Windows backward compatibility problems emulating ISA
Note: Standard ISA and ISA PnP cards, windows XP sound emulator and some On Board software
driven sound cards are not effected by this Windows/PCI legacy Bug, known as the
Testing your system for the BUG
To test your Game/Soundcard, first determine that your game runs and operates without
any-errors. Next load and try to enter E1L4(the start of the level puts you directly in a
nice "PCI Bug" fallout) If the game crashes or freezes..this Bug may be
your problem. Make sure you have the CD in the drive, so you don't mistake the
normal "Put CD in Drive" game dropout with the Sound crash.
Some other locations this Windows Bug can occur:
Episode 1, Level 2: In the sewer (behind the toilet and under the blown up building)
Episode 1, Level 3: Behind the church (after the cross inverts and room turns red)
Episode 1, Level 4: Crashes immediately!
- Playing in pure DOS tends to alleviate this problem for some. (not going into windows at
all, direct boot into DOS)
- If that doesn't work try updating your drivers/soundcard software.
- Some users simply suggest removing the tagged sectors (Duke) of a map to remove the
reverb effect. (Echo effector is as follows: the sprite is MUSICANDSFX (no. 5) with the
lotag set to a range of 1000 to 1255 inclusive, any sprites with these settings could be
removed to prevent the crash), Keep in mind this takes away from the games atmosphere and
is not ideal. I personally advise the Map Builder to continue to use the Echo (reverb) tag
and the patch/workaround (see below) together until such a fix is discovered.
- 3DRealms is aware of the problem, they have no patch/fix for this problem, and
will not have one. The problem can be corrected via the source code for the Apogee Sound
Engine (unreleased) or from your OS or sound card developers. Contact your sound card
manufacture and Microsoft to ask if they can help to resolve this issue. Explain in great
detail what is happening and provide them with your system's specs.
This is not a Apogee Sound Engine "problem" rather it is poor
programming in the
PCI TO ISA drivers and Windows Controllers.
Workaround: Ken Silverman has released a Echo Snd patch/workaround for Duke3D
and Shadow Warrior, It patches the game.exe to switch off Echo playback. However Reverb
through out the game is also switched off as a result.
Download The patch Ken-Build Site See the RTCM Other BUILD Games Mini sites and there
download sections to see if we have a patch tailored for your game.
A tidbit, workaround - no Windows Sound: This problem is not related to the PCI
Bug above, with that said...If upon exiting the game in a WinDOSBox, your windows sounds
may be "turned off." To re-enable them you need to re-initialize your sound card.
Simply open your Mixing controls (usually sits in your task tray, bottom right) and locate
your WAV settings, click mute and exit the mixer, wait, reopen then unmute, the WAV sound
should be restored for use with Windows. This is more typical when using Windows95.
