As I recall, IBM would send you OS/2 for free, on a bunch of the new-style 3.5" floppies. I think it was about two dozen floppies.
OS/2 1, the 286 version, was quite expensive enterprise software. I evaluated 1.0 in my first job.
OS/2 2, the 386 version, was relatively cheap. I paid about £40 for a copy, and it's one of the very few pieces of x86 PC software I've ever bought in my life.
OS/2 3 "Warp" did have a free evaluation version, and was distributed on magazine cover disks. However it took much of a CD and was not readily available on floppies.

I ran it on Librex laptops and several generic clones. No version ever _needed_ MCA.
It's just one of many things that doomed it. :-(
No one was selling it on OEM clones, and buying a PC clone was already expensive enough, to even think about trying to get an additional alternative OS at IBM prices.

This is what it looks like:
One of those catalogs was from Indelible Blue. It was basically a catalog full of OS/2 software. REXX scripting always fascinated me.
