Description mdiethelm 2006-05-15 13:37:54 MST 
+++ This PCR was initially created as a clone of PCR #3766 +++

Consider adding prose to the Deos Platform Integrator's Guide describing the inherent danger in using the Deos Platform Registry and PAL to map hardware interrupts to user visible exceptions.

Also, for those that are either inheriting prior designs, or contemplating using this feature, provide a registry inspection algorithm that a human can follow to identify any interrupts that are mapped to exceptions and then ensuring that the PAL cannot cause the interrupt.  This is needed to be in complaince with PALSRD, section 3.1, General Restrictions and Guidelines.

Recommend Deferral
The documentation is correct as written but could be made clearer, hence
Severity "Enhancement".
