I think also that there is some kind of confusion here - the original BP especially - because there is no such thing as running Linux in a subsystem - only OS/400 objects can run in a subsystem, if you mean what we think of by one of those.

Now there is something called Virtual Partition Manager that gives you a logical partition through software - no extra hardware needed. And Linux can run in it. Last we looked was in 2005 or 2006 right after it was announced and it was not available then - we've not checked lately.

guested LPAR is an LPAR in name only, its only physical resources are
shared memory and a fractional processor.  I believe this capability has
been around since V5R1, but you must have at least an S-Star processor
to take advantage of it.  That means some 820's and all 810 and 5xx
series boxes.

It doesn't actually run in a subsystem, it's more like a virtual IXS.
It uses the i5/OS for disk management and communicates through a virtual
ethernet connection.  It can also use either the physical iSeries CD-Rom
or virtual optical.  You need a 64-bit PowerPC version of Linux, ours is
set up to dual boot either SuSE or Red Hat.

The bottom line is that this requires no actual LPAR hardware
configuration, it can be run on any off-the-rack box with the proper
processor and OS levels.

Rob,

Thanks for the explanation but I was quite clear in what I was asking.
This
person said that Linux could be run as a sub-system within a single
existing
i5OS system - no LPAR, no nothing. Being new to the iSeries world I
thought
that a bit hard to believe so I wanted to clarify it in this forum of
knowledgeable people.
