Using Word 4.0 with a 68040-Based Macintosh

The information in this article applies to:


 * Microsoft Word for Macintosh, version 4.0

SYMPTOMS

Crashing and system errors occur when you run Word 4.0 on a 68040-based Macintosh. Typically, the problem occurs when you start Word. Currently, 68040-based Macintoshes include all Centrises and Quadras, some LCs, and some Performas.

CAUSE

The problem occurs because of an incompatibility between Word 4.0 and the 68040 chip inside the Macintosh.

RESOLUTION

On some Macintoshes, including the Quadras 700, 800, 900, 950, and 880AV, as well as the Centris 610, 650, and 660AV, Word 4.0 works correctly if you turn on the More Compatible (Caches Disabled) option in the Cache Switch Control Panel.

On other Macintoshes, including the Centris 610, 650, and 660AV, Word 4.0 unfortunately does not work.

If turning the cache off does not make Word 4.0 work correctly, Word 4.0 is not compatible. To obtain an update to Word 5.1, which is fully compatible, call Microsoft Sales Information Center at (800) 426-9400. If you are outside the United States, contact the Microsoft subsidiary for your area. To locate your subsidiary, call Microsoft International Customer Service at (206) 936- 8661.

MORE INFORMATION

The More Compatible (Caches Disabled) option slows the processing speed of the 68040 chip to the approximate speed of a Macintosh IIfx.

Use the following steps to disable the processor cache to see if Word 4.0 will run correctly on your Macintosh with the processor cache off:


 * 1) From the Apple menu, choose Control Panels.
 * 2) Select the Cache Switch panel.
 * 3) Select the More Compatible (Caches Disabled) option.
 * 4) Close the Cache Switch Control Panel.
 * 5) From the Special menu, choose Restart.

If the Cache Switch Control Panel is not installed, use the following procedure to copy it to the Control Panels folder from the Tidbits floppy disk: Note: The Tidbits disk is one of the disks that Apple provides with the Macintosh.


 * 1) Insert the Tidbits Disk.
 * 2) Drag the Cache Switch into the System Folder.
 * 3) You will see a message &quot;Control panels need to be stored in the Control Panels folder or they may not work properly. Put 'Cache Switch' into the Control Panels folder?&quot; Choose the OK button.

Note: The System Installer installs the Cache Switch only when performing a custom installation; many dealers use a default installation.
