RE: OS/400 on mambo emulator

Sorry, but cannot see how the below contradicts with what I've said.

Cheers,

Sorry , but that's not accurate.

On Power9 you have different flavours of the processor:

The regular one you use with S/E/H systems (S914, S922, S924, E980, etc) . All with SMT8 (up to 8 threads) CPU versions and PowerVM The ones starting with LC use SMT4 (up to 4 threads) and can't run IBM i nor AIX. I know, it's a marketing-technical mechanism on each OS, but there are CPU difference and I'm not sure you can run IBM i on SMT4
Power9 CPUs.

I've read about special hardware registers @ hardware level you need to make IBMi work, not sure, maybe just a Power ISA check mark...

Hmm, not sure about this.
You can run Linux on PowerVM LPAR on exactly the same hardware as AIX and i.
Linux is an officially supported OS on these servers provided by IBM.
I think you may be confusing it with some "unofficial" ppc linux versions
that could run on PS3 etc.
But there is no such thing as "i specific hardware" from IBM anymore.
That's why I'm questioning what do you mean by that? CPU? RAM? BUS?
Everything is unified nowadays.
The only thing that I'm aware about is the i-specific extensions in the
Power ISA that are still not officially published by IBM.
But I have a good reason to believe that the mambo emulator encompasses
them.

We've answered that question already.

IBM i, AIX run on POWER from IBM.

There are various Linux distributions that have also been compiled for the
POWER 64bit system as well.

Can you pls clarify what you mean by the "IBM i-specific hardware"?
As per my understanding, a nowadays IBM i is running on exactly the
same hardware as AIX or Linux called IBM Power Systems.
