This note discusses how to successfully use _ADBReInit on the PowerBook 140/170 and the Quadra 700/900/950.
In short, a bug exists in System Software that can cause the PowerBook 140/170 and the Quadra 700/900/950 to hang and/or crash anytime _ADBReInit is called. Although it is possible to hang and/or crash those machines ANYTIME _ADBReInit is called, informal testing seems to indicate that it is more likely to happen while Apple Share is active (i.e. File Sharing is turned on). The bug allows memory to be moved at interrupt time, and the ADBReInit extension prevents this.
Although _ADBReInit is normally never called on a Quadra, there is a specific instance that the PowerBook 140/170 make use of the call. When coming out of Sleep mode, the PowerBook 140/170 calls _ADBReInit if external ADB devices are attached.
In this folder you will find an extension called "ADBReInit" that appears to fix this behavior. At some point in the future, this fix will be rolled into System Software.
In order to be able give the extension to customers who experience problems with
ADB ReInit and your products you must call Apple Computer Inc.'s Software Licensing department and ask for a Software License form for the ADB ReInit product. Upon signing the software distribution agreement form, you will receive a no-cost license.
Note that Apple Computer, Inc. will not be responsible for it's use or consequences thereof.
