IIRC a z890 will only run a OS in 64-bit mode, no 31-bit mode, in an
LPAR. It may be possible to run a non-64-bit OS under z/VM.

Hello -
I have been asked to identify if it is possible to run an old,old version
of MVS/SP and DFP (3.2) on a zSeries processor (z890). (this is not an
April fool joke)
Putting aside the issue of lack of support for such an old release, I
seem to recall that
nothing older than OS/390 R10 will run on zSeries.
Anybody have any positive comments on this?
Is there a way to run MVS/SP under some supported version of VM on zSeries?
I have found a few hits on old releases of MVS in the archives from 1995
and 2000,
but nothing specifically addressing this scenario.
Thank you,
