Hello,
I found this link among similar ones about a big project - which was cancelled later
https://macintoshgarden.org/apps/ibm-os2-warp-powerpc-editionThat is about a special Warp 3 running on some workstations and laptops
with PPC processors as first fruitition of a Unified OS of All (Workplace OS).
"IBM OS/2 Warp PowerPC Edition was a port of OS/2 Warp 3 to the PowerPC Reference Platform (PReP). It was a subsystem (OS/2 personality) running on the IBM microkernel, which was a refinement of the Carnegie Mellon University Mach microkernel. It was a first step to Workplace OS (or WPOS for short) was supposed to be built on top of the Mach microkernel and support multiple "personalities". The personalities would implement existing operating systems such as OS/2, AIX, Windows NT and perhaps even Mac OS. In the end this never happened and the only supported personality was OS/2."
Applicable hardwers were only :
---------------------------------
"Compatibility
Architecture: PPC
Installs only install on IBM PowerPC workstations and on Motorola PowerStack (PowerPC Reference Platform (PReP)).
Compatible IBM PowerPC workstations:
%u2022 Desktop:
Personal Computer Power Series 830 (PowerPC 604)
Personal Computer Power Series 850 (PowerPC 604)
%u2022 Laptop:
ThinkPad Power Series 820 (PowerPC 603e)
ThinkPad Power Series 850 (PowerPC 603e)"
Also among early RS/6000 you would find not just POWER but PPC versions as they started also with those processors as well.
On those it could not be hard to attempt to install this environment especially which was Prep version also and even not Microchannel but PCI bus if those above mentioned 2 PPC workstations and 2 PPC laptops were built such way.
So, let's check it out ...
You can read this on wiki page of rs/6000 about it -- starting section History :
"The first RS/6000 models used the Micro Channel bus, later models used PCI. Some later models conformed to the PReP and CHRP standard platforms, which were co-developed with Apple and Motorola, with Open Firmware. The plan was to enable the RS/6000 to run multiple operating systems such as Windows NT, NetWare, OS/2, Solaris, Taligent, AIX and Mac OS but in the end only IBM's Unix variant AIX was used and supported on RS/6000. Linux is widely used on CHRP based RS/6000s, but support was added after the RS/6000 name was changed to eServer pSeries in 2000."
https://en.wikipedia.org/wiki/IBM_RISC_System/6000 When I searched for
"Personal Computer Power Series 830 (PowerPC 604)"
I got the following wiki
https://en.wikipedia.org/wiki/IBM_PC_Seriesand here there was a section :
XXXXXXXXXXXXXXXXXXXXXXXXX
PC Power Series
This is the PC counterpart of the RS/6000
PowerPC 604 processor at 100, 120 or 133 MHz
ISA/PCI PReP architecture
16MB parity memory standard, expandable to 192MB
Integrated 10baseT Ethernet, PCI Graphics and Audio
Supports Windows NT 3.51 or AIX Version 4
ARC BIOS
Two form-factors were available, the 3x3 (3 slot, 3 bay) PC830 and the larger 5x5 (5 slot, 5 bay) PC850.
XXXXXXXXXXXXXXXXXXXXXXXXX
Well I left out the table following, but you can chech it out personally
I assume one of those RS/6000 machines were attempted to install and run that limited beta OS2 Warp3 OS personality on it.
So it was possible to run the OS, but it was not a generic PPC solution, you may hope for,
there were not even network subsystem in it, or many applications ported .. except some listed on the first link above, rather like a pure OS "demo".
From the first link :
"IBM OS/2 Warp PowerPC Edition was never released as a product and was only offered to interested IBM customers as CD pack (2 CDs: "OS/2 Warp (PowerPC Edition) December 1995 Version" and "IBM Applications Sampler"). It stayed in beta status until cancelation of the OS/2 PowerPC project in 1996.
IBM OS/2 Warp PowerPC Edition had all features of its Intel counterpart OS/2 Warp 3 (including DOS and Win-OS2 support), but missing all the networking functionality of the "Connect" versions. It had a beta version of OpenGL support, which shared code with IBM's AIX workstation class implementation. Moreover, it had already many features that showed up later in OS/2 Warp 4 on Intel."
I hope these links might fullfil everyone's curiosity,
but sadly and possibly not their satisfactory.
Also however its downloadable .. playing with it possibly hard as you shuld buy compatible (rare) PPC hardwer as well .. which one should be funtioning well as expected.
For virtualized solution I suggest to read comment posts also on the first link above - this way proposed the compatible bare metal.
