I don't know how 386/ix runs, but Desqview can use QEMM to emulate LIMS
if you like.  I am not overly familliar with DV and how it works yet
but I figured it was running in the protected mode for a speed increase.
I tried running Landmark under DV and here are some results:

Results are for an Informtech 386SX/20 motherboard with Pheonix BIOS.

Landmark under DOS 3.3              ==> 24.3
Landmark under DV (active window)   ==> 30.3
Landmark under DV (background task) ==> 34.0

What I don't understand is the speed increase gained by being a
background task.  Anybody?
