As far as the IDS warning always showing up, I believe it's designed 
to
remain active until explicitly cleared by an administrator in the 
BIOS/CMOS
setup. Since that would normally be password-protected, it ensures 
that an
administrator will see the alert. What originally triggered it may 
have
been a one-time event.
