What This Diskette Does

This patch is an updated version of the Greater than 16 Meg patch and the Sierra Games patch (combined). It is intended to fix six problems:

- The 16 Meg Patch (PAMW44C1) caused MIDI to fail after several start and play attempts.
- Running applications using sounds authored with Macromedia Director
- Beta Support for running Mwave under Windows 95
- Fix MIDI-IN Bug
- Fix Several problems with CD-based games from Sierra On-Line, Inc. (Kings Quest VII, Policy Quest - Daryl F. Gates Open Season, etc.)
- Fix problems with After Dark 3.0 and general MIDI hangs

This patch is intended for limited distribution to IBM customers. This patch has received limited testing before release by IBM, therefore we suggest you back up any critical data on your hard drive before applying it. Upon the next release of Mwave code this patch will be obsolete.

Macromedia Problem

When running applications which use sound files authored with Macromedia Director, several different symptoms of this problem may be observed. A loud pulsating static type sound may be heard over much quieter music or short static beeps or trills may be heard. In addition the system may hang in any phase of the application.

16 Meg Problem

On systems with more than 16 Meg of memory, it is possible for Mwave to fail due to DMA restrictions. The failure most often shows itself as the inability to play sound. This version of the Mwave run-time detects when it is being run on a system with more than 16 Meg of memory, and it then takes the appropriate precautions.

Restrictions: To use this fix, you must make sure that an adequate amount of memory below 16 Meg is available before starting Windows. While this is not usually a problem, it can become a problem if you use programs like SmartDrive and RAM disk utilities that can be configured to use large amounts of extended memory. If you use such utilities, we recommend that you restrict them to using less than 6 Meg of extended memory.

Windows 95

This patch serves as Beta support for Windows 95.

MIDI-IN Fix

This patch fixes a problem with Mwave causing a hard system lockup in some instances while recording MIDI files using the external MIDI-IN port.

Multiple Stop and Play Attempts after Applying 16Meg Patch

After applying either the 16 Meg patch, or the Sierra Games patch, attempts to stop and play MIDI repeatedly would fail. The error message was usually "No MIDI Device Found". This patch combines the 16 Meg patch and the Sierra Games patch and fixes this bug.

Sierra Games Alt-Tab Problem Description

While playing the game, an attempt to switch to the Windows Program Manager by pressing Alt-Tab will cause a system hang. The banner from the Sierra program group is usually displayed on top of the game scene. The user must power down to recover. Hangs occur randomnly, requiring as many as twenty Alt-Tab attempts before failing.

Sierra Games Randomn Hangs Problem Description

At randomn, whithout user input and usually during scene changes, the game will hang. The scene typically locks but the cursor may be free or frozen. At times, the game will abort and a DOS-like screen will appear. Or a real DOS screen will appear and the system may even reboot itself.

After Dark 3.0 and other MIDI GPFs and Hangs Description

While using this screen saver application (that plays MIDI files) a GPF may occur in the "midimap.drv" file or the display may freeze up when attempting to unlock the screen saver. Or while using any application that plays MIDI files, a GPF, system hang or a boot out of Windows back to DOS may occur.

Patch Scope

This patch is for a Windows and/or WIN-OS2 environment only.

Patch Prerequisites

1. Mwave Version 1.1 needs to be present on your computer.

2. Users of Macromedia Director versions prior to 4.04.1 must obtain from Macromedia an additional file, MACROMIX.DLL. This file should be put into the same directory as the Director application or any "projector" (stand-alone executable) created with Director. Alternatively, users may upgrade to Director Version 4.04.1.

Macromedia Technical Support can be reached at 1-415-252-9080.

Patch Instructions for Windows 95

1. Upon booting Win 95, press F8 to get a DOS prompt. Then follow the instructions below for Windows 3.1x.

Patch Instructions for Windows 3.1x/Win-OS2

1. From a regular DOS prompt, or from an OS/2 DOS box (Windows/WIN-OS2 **MUST** be closed) execute the patch by performing the following steps:
a. type a:install
b. Install will try and locate all of the Mwave Directories, WIN-OS2, and Windows. If it does not find everything you have installed, answer "no" when it asks if everything is correct. Install will then prompt you for the location of each installation. Install will attempt to update Win-OS2 and Windows. If you do not have both installed, the install program will complain, but will successfully install the patch on what you do have installed.

2. If your computer has more than 16 Meg of RAM, edit the SYSTEM.INI file in the Windows directory. Add the following line to the "MWAVE" section of the SYSTEM.INI file: DMABufferSize=4096
If your computer has 16 Meg of RAM or less, you do not need to make this change.

The "DMABufferSize" setting will cause Mwave to reserve a block of memory below 16 Meg for its own use when transferring data to and from the Mwave hardware. This value is in kilobytes, so the above setting actually results in reserving 4 Meg for Mwave's use. If you are not using the MIDI Synthesizer, you can reduce the value to 350. If you see out-of-memory errors from Media Player (or other MIDI application), try increasing the value and then restarting Windows.

3. When install completes, you may start Windows or Win-OS2 and the changes will take effect immediately.

Once the image is created, the following files should be present:

Volume in drive A has no label.
The Volume Serial Number is E5B0:1C15.
