Sadly, that might be correct.
After building Hyperion 4.7, I still cannot get either of them past
launching /init. Final trace at the end of this note.
I'll have to try a different distro. Been using SUSE variants as primary
for a long time.
Am skeptical of Red Hat because they're owned by IBM and IBM *does* push
for the latest hardware capability. (see end)
So prolly Debian. Ugh ... major learning curve there for me.
Here's the latest in case it says anything to anyone who can give me a
clue.
There's a bit of disassembly in there (nice!), and I grok assembler, but
I don't know quite how to interpret this.

This is way better info than I was getting out of Hercules 3.13.
Thanks for the tip, Mark!
A request:
Distributors, _please avoid latest-and-greatest_ when building your
installers. Not everyone can afford to fork-lift a Z16 in a pinch.
Y'ALL KNOW how to build code which is broadly runnable. Just do so:
install first, optimize later.

IOW OpenSUSE S390x on top of Hercules, not Hercules on top of OpenSUSE. IIRC
the more recent versions of OpenSUSE and RedHat (I think RH 8.x) require
certain instructions that are not supported on Hercules. I goofed around with
RH 8.x and think I got it to work using qemu s390 but cannot say for sure as it
was a couple of years ago. I didn't really need anything higher than RH 7.x so
it was just an exercise.
Regards,
Paul

Greetings Truth
To clarify, you are operating SUSE Tumbleweed as the base system on
some random intel-type iron. On top of this you want to operate
Hercules, apparently this is part of your studied plan for world
domination. (I am good with this :^)
This is where I get a bit confused. I use Hercules to boot IBM VM 370.
This was enough of an entertainment that I folded Hercules and VM into a Docker container
and stuck the whole beta out there as "BaBy Bear VM"
(http://bbbvm.org/),
So the question I have is do you need code to run on top of Hercules on top of
Tumbleweed, or did I misunderstand?
If you are interested, this evening the Barre Open System Institute (BOSI) has our
regular meeting at the York Library in East Barre, we shall use meet.jit.si/bosi to

Months ago, I tried other releases/snap-shots. No joy then either.
I have tried supplying the kernel, INITRD, and parm file via 00C reader.
Didn't work. I have also tried Hercules IPL from ".ins" file.
After about 4 or 5 minutes, the run consistently ends with something
like ...

... sometimes followed by (what appears to be) a wait state code,
sometimes not. In all cases the emulator stops with a disabled wait.
My preference is OpenSUSE Tumbleweed, but Leap works "if I gotta".
I'd like to install to un-partitioned FBA, but I've switched to CKD
in case FBA was/is causing the installer heartburn.
I've also tried to change the device addresses to match what the
samples have. Still nuttin, honey.
What am I doing wrong?
