The thing, whatever you call it, that purposely slows the CPU down to
20% of its capacity.

How do the engineers at IBM slow the system down?   Is it just a slow
clock on the motherboard that can possibly be replaced with a faster
one?  Is there a version of CFINT running continuously on the system
that does not show up in WRKSYSACT?

Would be interesting to know what are the hardware differences between
the pSeries 520 express and the iSeries.  What is it that prevents
i5/OS from running on the non geared down pSeries?  The redbook on the
subject says it will only run on large, expensive pSeries models, and
there is an iSeries specific feature that has to be added. Not sure if
the feature is hardware or software.
