File: Using Version 2.00 With the Macintosh Quadras
Last reviewed: October 27, 1994

Article ID: Q79522

Summary:

If you use Microsoft File for the Macintosh version 2.0 on the Apple Macintosh Quadra 700 or Quadra 900, you must set the Cache Switch control panel to the More Compatible (Caches Disabled) option to ensure that no compatibility problems exist.

To do this, follow the steps below:


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

Microsoft File version 2.0 should now run correctly.

Note: In order to have this Control Panel installed, the Macintosh must be running Apple System 7.0.1.

If the Cache Switch is not available in the Control Panels folder, use the following procedure to copy the Cache Switch control panel into the System folder from the Tidbits System disk:


 * 1) Insert Tidbits System disk.
 * 2) Drag the Cache Switch into the System folder of the Quadra.
 * 3) You will see the 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;
 * 4) Choose the OK button.
 * 5) From the Apple menu, choose Control Panel. Double-click on Cache Switch. Select More Compatible.
 * 6) From the Special menu, choose Restart.

The Cache Switch is only installed by the Installer when performing a Custom Install.

This option slows the processing speed of the Motorola 68040 CPU to the approximate speed of a Macintosh IIfx.

More Information:

Microsoft File for the Macintosh versions 2.0 and 2.0a may also display the following message in System 7.0.x:

The application &quot;Microsoft File&quot; has unexpectedly quit, because an error of type 1 occurred. This happens because 32-bit addressing mode is turned on and Microsoft File is not 32-bit addressable. To correct this problem, follow the steps below:


 * 1) From the Apple menu, choose Control Panel.
 * 2) Double-click the Memory icon.
 * 3) Select the Off button in the 32-Bit Addressing section.

On an Apple Macintosh Quadra 650 running System 7.1, the error message is as follows:

The application &quot;unknown&quot; has unexpectedly quit, because an error of type 3 occurred
