Can anyone provide me with some detatiled information on the use
of the CAS and CAS2 instructions.  There is mention of their 
ability to provide for secure updating of system info.

How can it provide security if it isn't a privileged instruction?
Any clarification possible?

PLEASE mail to me as I don't follow this group closely.
