If your OS doesn't support the z13, don't run it on the z13.  Depending on 
your z13 hw configuration, any operating system that does not explicitly 
support the z13 will very likely fail.  It could be a noisy abend, a hang, 
or silent data corruption.  The only solution is to upgrade the OS to a 
supported level.

One of my clients hit this when they went to GA2 and upgraded to a bigger 
model.
