3D Lemmings

Technical Support and Installation Addendum

3D Lemmings makes use of state-of-the art programming technology and hardware. Because of this, 3D Lemmings may require special installation procedures to work properly on your particular configuration.

Minimum Requirements:

486DX 33 mhz, recommended 486DX2 66 mhz

MS DOS 5.0 or above

4MB Ram, 2.5MB EMS, Conventional memory at 590K

SoundBlaster Pro 16, AWE 32, or Gravis Ultrasound

Installation Problems?

3D Lemmings is a DOS based program and must be run from DOS. Windows must be shut off completely in order for the program to run properly. To exit Windows 3.1/3.11, just click "File" from the Program Manager and select "Exit Windows". For users with Win95, You must click "Start" from the Start menu, "Shutdown", and "Restart in MS-DOS mode". When you get a C:\>, just switch to your CD ROM drive and type "Install".
It is possible to get the game to run under Win95, in very specific circumstances. Download this PDF file, which can guide you through the process.

Music & Sound Problems?

Once the game is installed, type "Setup" from your CD-ROM drive (usually D:) to select your sound and music cards. You must have a 16-bit or 100% SoundBlaster 16 compatible.

Still no music?

Well, in your Autoexec.bat file, make sure that you have a line that sets up your sound environment. It varies from system to system, but generally looks like this:

Set Sound=C:\SOUNDDRIVERS

Where the SOUNDRIVERS is substituted for the directory your sound card's drivers are in (usually C:\SB16)

What? No sound effects?

Also in your Autoexec.bat file, make sure that you have a line that reads somewhat like this:

Set Blaster=Axxx Ix Dx Tx

This statement lets us know what hardware settings your sound card is using. The usual values are hex address A220 , interrupt I5, DMA channels D1 and T1.

Why isn't the mouse responding?

Check in your Autoexec.bat file to see if you have a mouse driver installed. If not, then look for your mouse driver and install it as per the install instructions provided with it.

Once your driver is installed, your Autoexec.bat file should have a line that reads:

c:\mousedir\mouse

Insufficient base memory?

If you do not have sufficient memory to run 3D Lemmings on your configuration, free up some DOS memory by either removing some TSR's, or booting from a disk which is free of device drivers and TSRs (TSRs and device drivers are memory resident programs which can take precious conventional memory). In addition, MS-DOS 5.0 and above have special facilities to help you free up DOS memory. The DOS command CHKDSK will tell you how much free memory you currently have available. 3D Lemmings runs with expanded memory. Therefore, your Config.sys file should contain the line:

EMM386.EXE RAM

To free up enough base memory, proceed to the boot disk information on the following pages. A simple Autoexec.bat and Config.sys file will easily free up enough memory to run 3D Lemmings.

What is a "CDR101:GFX Mouse.RNC"?

That could be caused by either your EMS not being enabled, not enough conventional memory, or because your CD animation is on. For the EMS and conventional problems, proceed to the boot disk information on the following pages.

For the CD animation, type "Setup" at your CD ROM prompt and select "Setup Hardware" go to "Graphics" and turn your CD animation off. Then save and exit and try to run the game again. When you get the "Abort, Retry, Fail" message, press "R" for retry twice. That should take care of the problem for you.

This problem is caused by non-standard CD-ROM device drivers, and may also be fixed by contacting your CD-ROM manuafacturer for an enhanced driver update.

Getting a "DOS 4gw Error: Not enough memory"?

You must create a boot disk and disable Memmaker, Smartdrive, Share, and also QEMM.

To get this error, you probably have one at least one of these programs active. Please proceed to the boot disk information on the following pages.
