First of all, few 386 systems had any provision for cache.  The 40
MHz clock indicates that yours would be a relatively late model, and
so the board *might* provide for 64K of cache.  [It's possible that
you have a BIOS that can support cache, mounted on a board that
cannot....]

  386 systems generally predate the ability to auto-detect the amount
of installed RAM; there is probably a jumper to enable the second
bank.  (My 386 had one....)  Unfortunately, (a) you haven't
identified the motherboard, and (b) 386s are pretty much before the
rise of the web, so many manufacturers have probably never bothered
to put manuals on line going back that far.
