No, no reference. It does reference IDS which never really applied to the IOS IPS, I am pretty sure that it has always been able to operate "inline". I guess it could be that old, almost have to be pre x700 series and I couldn't even guess at the IOS version. The 4.x signature set was larger than 100 signatures and that hasn't even been updated since middle of last year. So it seems that 100 would be very old.
Given that the question doesn't reference a version, would the best approach be to answer based on current code?

That's my initial guess. Is there a reference link?
