DOS simply loads TSRs, it doesn't 'manage' them.
Then what gives each program time on the CPU?
DOS is single-tasking. In DOS, there is only ever one program at a time
executing. The currently executing program "owns" the machine. There
is
no "executive", there is no time slicing of CPU time.
I fell in love with DesqViewX. It was among the first for the early
x86 architectures to slice things up well.
Yeah, I ran DesqView and DV 386 (not X) for years. I actually got X but
never used it.
