SYMPTOMS
When you use a device that is running Windows CE 3.0, the device may not detect an MMX-compatible processor.



CAUSE
This problem occurs because the algorithm that is used to detect MMX-capable processors does not properly identify GEODE processors as MMX capable. The detection code has been changed in the fix that is listed in this article to attempt an MMX operation and catch the exception. If no exception occurs, the processor is assumed to be MMX capable.



RESOLUTION
A supported software update is now available from Microsoft as Windows CE 3.0 Core OS QFE 42. To resolve this problem immediately, click the following article number for information about obtaining Windows CE Platform Builder and core operating system software updates:
