were exactly the same in some beginning, but at some time it became too complicated or so (we have this ERP package). And as I understand, you just know more about it all {s}

Now since it all is over 10 years ago when it was setup (for 2.5) I can't recall exactly what the problems were, but they were there, that's a fact. So maybe we applied some tricks (without knowing) ?

Just for fun, this is my W2K CONFIG.NT :
dos=high, umb
device=%SystemRoot%\system32\himem.sys
files=255
In NT4 it was the same, and I just checked a few W95 overhere : there's nothing in the CONGIG.SYS anymore (but EMS is checked to Off in some config form).
