All I can definitely say is that the version of Win95 that came on a bunch of
machines we bought at one time for a lab, would not recognize beyond 128mb until
our windows guy installed an update.  Linux would see the memory just fine, so
it wasn't a hardware problem.

As far as caching, that isn't a windows issue as it has absolutely no control
over the cache hardware.  Several vendors used a particular intel chipset (I
don't recall the name of this chipset) that would only cache the first 64 megs,
but that was just a poor hardware design as they only included enough TAG ram
for 64 mb, and if you added more memory beyond 64mb, it bypassed cache and made
the machine slow way down...

We also had versions of linux that would stop at 16mb, etc...  But not for a
long time now.
