OS/2 2.11 SMP Bootable CDROM 10 Minute Installation Hack into VirtualBox

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 :no: higher resolution than 640x480...

(Once the video player has started, right selecting (or 'clicking') your device (or 'mouse') will show menu option, 'Open video in new tab', which will enable larger screen size. Alternatively, the video with larger screen size may be shown in the Calli, i.e., 'Home', collection front page)

NOTE: If you want to acquire this OS/2 2.11 SMP Bootable CD/ISO image hack, it comes in a bottle opener USB stick:
