Solution:
Floating Point Unit (FPU) exception hander information for Intel® processors is available in the following documents:

Application note AP-578, Software and Hardware Considerations for FPU Exception Handlers for Intel® Architecture Processors, Intel® Document #243291. This application note provides information to help software engineers write the most robust Floating-Point Unit (FPU) exception handlers possible.

Also see the Intel® Pentium® Processor Family Developer's Manual, Volume 3, Intel® Document #241430, contains three chapters about programming the floating point unit, including one chapter dedicated to programming examples.

Also see the Intel® Architecture Software Developer's Manual, Volume 1: Basic Architecture, Intel® Document #243190, Chapter 7 and Appendix C.
