Yup. The multitasking European DOS 4 was a different animal from the
commonly-known MS-DOS 4.
Later versions of DR DOS included a task-switching or multitasking
capability. The heavy lifting was performed by the memory manager,
not the DOS kernel. You needed at least a '386 for multitasking. I don't
recall whether the simpler task-switching option also required a '386, or
whether a '286 would suffice.
