Procedure to install Mathematica v2.2 for OS/2 in my local copy of the VirtualBox 7.0.12 OS/2 for SMP v2.11 with HPFS386 virtual machine hosted in my four(4) CPU / eight(8) CORE Metztli Reiser4 development environment.

Subsequently this VirtualBox vm will be uploaded to a remote server, with a Metztli Reiser4 for AMD CPUs environment, i.e., reizer4, and I will utilize VBoxManage to increase the cpu count to 16 in the headless environment.

Although the visual media is self explanatory, I included a few Mathematica for OS/2 installation procedure snapshots which may be of relevant historical interest:

Mathematica for OS/2 2.11 on SMP: 'Klein Bottle'

As an addendum to my previous 'Mathematica on OS/2 Symmetrical Multiprocessing (SMP) for v2.11 Guest in VirtualBox 16 CPU/Cores' post in Collection Ixiptli, I remembered I had seen the so-called 'Klein Bottle' in an older manual I had many Metztli  ago.¹

¹ Notwithstanding, at that time, the front window of my car was broken and my backpack was stolen in San Francisco as I had parked, on the street, next to San Francisco State University -- and I had that manual in there.

There was, still is, something appealing about OS/2 -- it was ahead of its time, Warp indeed -- The Integrating Platform. I came across some relevant resources and created an OS/2 2.11 Bootable CDROM media for VirtualBox -- as I heard, through the grapevine, that it was undoable.

OS/2 enabled me to learn Unix by utilizing the GNU/Linux utilities ported by OS/2 hackers. Accordingly, once IBM orphaned the OS/2 -- and the executives even balked at our multiple petitions to have the OS open sourced -- the transition to Linux was relatively painless. As a matter of fact, while creating this hack I had to bring my old ported GNU/Linux utilities, alternating between OS/2 2.0, 2.1x, and even Warp 3, environments so as to alleviate the shortcoming of 640x480 resolution.

Due to the scarcity of information, I usually operate by inductive reasoning. Notwithstanding, I came across the following 'nugget':
OS/2 has supported SMP for quite a while in special editions of OS/2. The first version was 'OS/2 2.11 for Symmetrical Multiprocessing'...
The diffences between the single-processor OS/2 and the SMP version are very small: 2 APIs for controlling the CPUs, an extra index for DosQuerySysInfo() and 4 APIs for dealing with spinlocks. I know that the 'SMP addendum' mentions a lot of other things, but they are server things, not SMP things.

'OS/2 2.11 SMP' supports up to 16 processors,...¹

Yet my build of VirtualBox, from source, under a Metztli Reiser4 Debian environment can only go up to 8 processors/cores and higher resolution than 640x480...

Update 12-18-2022 : my personal development computing environment can only go up to eight(8) cores; however, I installed another Oracle VirtualBox 7.0.4 -- although 'headless' -- in one of my remote Metztli Reiser4 servers. I made use of VNC to make connection and although Remmina experience a buggy pointer (or mouse) I was able to bring up the SMP Monitor. I could not delay this event as it is not everyday that an OS/2 for Symmetrical Multiprocessing (SMP) Version 2.11 is seen running on 16 CPU/Cores!

OS/2 for SMP v2.11 Reference at Hobbes but requires OS/2 INF VIEW.EXE utility or 'INF READER'

"

In OS/2 for SMP V2.11, all of the platform specific code has been removed from the operating system, and placed into a Platform Specific Driver. These drivers provide an abstraction layer for the underlying hardware by allowing the operating system to call generic functions to perform platform-specific operations without worrying about the actual hardware implementation. This allows OS/2 for SMP V2.11 to support new MP hardware platforms without modifying the operating system.

PSDs are 32-bit flat DLLs specified in CONFIG.SYS by using the PSD= keyword, and must conform to the 8.3 file naming convention (e.g. PSD=BELIZE.PSD). They cannot contain either drive or path information because OS/2 cannot process such information at the stage of the startup sequence when the PSD statements are processed. The root directory of the startup partition is first searched for the specified file name, followed by the \OS2 directory of the startup partition. If drive or path information is included in a PSD statement, an error is generated.

PSD parameters may be specified after the PSD's name, and may be a maximum of 1024 characters long. The parameter string is not interpreted or parsed by OS/2, but is passed verbatim as an ASCIIZ string when the PSD's Install function is invoked.

If multiple PSD statements are encountered, OS/2 will load each PSD in the order listed in CONFIG.SYS, and call the PSD's install function. The first PSD which successfully installs will be the one OS/2 uses.

PSD statements are processed before BASEDEV, IFS, and DEVICE statements."

->\OS2\INSTALL\PROLIANT.PSD
->\OS2\INSTALL\WYSE.PSD
->\OS2\INSTALL\ALR.PSD

(The above are typical of middle of 1990's Compaq software bundle where OS/2 for SMP v2.11 was an option; notwithstanding, I believe that the maximum number of CPU/COREs supported was eight(8))

CAVEAT: I have seen some videos/statements out there where the OS2APIC.PSD is simply extracted from a higher version OS/2 for SMP and rammed in with an OS2KRNL with none or limited support for SMP, i.e., a two- CPU/Core OSKRNL with a Warp4 and/or WSeB -donated OS2APIC.PSD presented as an four(4) CPU/CORE SMP in a YouTube video out there. Well, yes, the pseudo- SMP OS/2 will experience frequent severe locks during execution. Yet, the narrator will blame those events on legacy OS/2 SMP 'instability' to hide his technical deficiency instead of admitting that he is cheating -- making fraudulent claims to defame the legacy OS/2 technology! i.e.,

Although IBM OS/2 3.x Warp and higher indigitalizations have been hacked into bootable CDROM media / ISO images, I believe this is the first OS/2 2.x which has been morphed into such an unique entity. The procedure was not easy -- and obviously not intuitive. The work required to make the cdboot hack complete the first phase of the OS/2 2.1 installation was substantial; and once I achieved it I thought that whatever else needed to be done would be easier. I was mistaken. I had to compile an utility to search for and replace strings in the OS/2 2.1 CONFIG.SYS file at the end of the first phase of the OS/2 installation -- as I could not find an appropriate binary one in my extensive local collection of Hobbes CDROM media, etc., nor online at Hobbes site and/or elsewhere.

Had IBM released the OS/2 code as free and/or open source software (FOSS) instead of being so indifferent to the multiple petitions to do so (for instance those in which I personally took part at the OS2World site before I left the site for good -- as I had moved on to GNU/Linux Debian) the avaricious plutocrat Bill Gates' mediocre 'creation', backdoored software, idiotically named as a mundane household notion, 'windows,' would not have spread like the virus it emulates.

Generating an OS/2 2.1x bootable CD under GNU/Linux Debian -based Metztli Reiser4:

Shell

Generally speaking, even if your bootable two(2) disk image is successfully created, if  it can not make the transition to the OS/2 disks layout on the CD, i.e., can not detect it due an older driver like IBM1S506.ADD (see snapshot below), the boot procedure will stop with the output:

The system cannot find the file "A:\COUNTRY.SYS". This device driver, program, or data file is not located in the default path or the path specified for it in the CONFIG.SYS file. Install this file in the correct directory, or correct the appropriate CONFIG.SYS file statement.

The system is stopped.

Correct the preceding error and restart the system.

Shell

If, unlike myself, you are not using the Korn Shell under OS/2, then the command delimited by double quotes is sufficient.
