Hi,

I tried flashing the IT firmware on top of the IR firmware as suggestion
on this LSI page:

http://kb.lsi.com/KnowledgebaseArticle16266.aspx

I followed exactly the instructions but when trying to flash the fw I
get this error:

	"Failed to validate MfgPage2 !"

See the attached screen capture.

Any help would be much appreciated, thanks
