i find that if i try to boot into windows95 or win3.1 i get significantly more
memory available, but then the programs i try to run say 'im sorry you cant
run this from a dos box' :) which is rather ironic.

this former idea sounds interesting, in particular because mem reports
having 15meg free xms (ems isnt configured on this machine) it's infuriating
as the program in question needs to run on this machine but i cant edit any
of the files or change the setup in any way :(
