Doug,
excellent brain-dump of all your knowledge
a couple of questions:
why make the partitions for the swap file primary ? I have never done this
but I'd have thought WinNT wouldn't be able to see the partitions.
how do you make the NT paging file size *fixed*? The only options i see in
the virtual memory dialog box on NT are for Initial Size and Maximum Size -
actually I can answer that - you make them the same, right?
thanks
Adam
