EDAC is designed to report errors in the core system.
These are low-level errors that are reported in the CPU or
supporting chipset: memory errors, cache errors, PCI errors,
thermal throttling, etc.. If unsure, select 'Y'.
+ If this code is reporting problems on your system, please
+ see the EDAC project web pages for more information at:
+
+ <http://bluesmoke.sourceforge.net/>
+
+ and:
+
+ <http://buttersideup.com/edacwiki>
+
+ There is also a mailing list for the EDAC project, which can
+ be found via the sourceforge page.
