Hmm, AFAIK, Win3X will never use DPMI, that DOS only, DOS Protected Mode...if you mean allow Win3X to address all memory above 640kb, that is already built-in, it maps all memory up to around 64 megs. The other solution is to install the WIN32s, this will enable 32 bit access also. As for using newer versions of EMM386.EXE, or HIMEM.SYS, you should be able to...just copy say the ones from a WIN95 machine into the sub-directory DOS, rename the older ones JUST IN CASE. Win3X doesn't check "version" of these drivers IIRC, only that they are loaded. See you later!
