If it was OS/2 from IBM it was true multitasking and the OS in full control of memory allocation, something Microsoft only were able to offer after creating a new operating system from scratch (Windows NT).
If you thought OS/2 took forever to boot on a 386DX with only 8MB of ram, imagine how long it would take to boot Windows NT 3.5 on that same machine…
Windows NT came out of the failed collaboration with IBM and was originally meant to be OS/2 3.0. MS switched the APIs from OS/2 compatible to Windows compatible after Windows 3.0 took off, and it caused the collaboration to fall apart.
