Remember, they added a facility at the same time to patch out any
of the resident modules into ram.  The only problem here is granularity
(You would need to replace *all* of Intuition, for example).

Well you could hit the jumper and disable it.  Or get the new Fat Agnus
and make it CHIP ram :-).  ( add some more :-)'s for some more insight
into how V1.2 Kickstart sizes CHIP )

Since I boot from a Kickstart disk I have no need for a ram patch,
but it would be easy to do.

Andy Finkel was onto this bug before I was.  It was a totaly accident
that I ran into it.  (Well not totally, I knew about the bug and kept
my eyes open).

I suspect a CATS patch soon.  What I hope more is that they will
throw this into V1.21 before it goes out.  (The change is minor
and can have *no* bad side effects)


Anyone have any other Kickstart hacks they would like to see get
wider fame?  I'm putting together a collection.


BTW: There appears to be life at the other end of comp.sources.amiga!
