Here's what I've been told recently about CWSDPMI (straight from the horse's mouth):

> Actually r5 and r6 both support 2GB of RAM. But r5 will need to
> page fault the page directories to access the 2GB. So a hack that
> was used before r6 was to create a Ramdisk of about 2MB, and
> put the CWSDPMI pagefile on the ramdisk. Yep, it worked.

> 4GB, by using 2GB of ram and 2GB of pagefile. And once again,
> the pagefile could be on a ramdisk... Yes, people get creative, but
> it did hurt performance even paging to the ramdisk.
