Nope, NT is top down as well. This caused an issue with early PII
chips as well, not only could they only cache 512M, but there was a bug in
the cache controller if you added more than 512 it would mirror the writes
below 512. A PII with 768 ram, and the L2 enabled would crash before it
was able to blue screen.

Depands on the BIOS, a few disabled all L2 caching if more than 64
was present, however most mainboards (both VX and TX chipsets) simply
cache the first 64, and don't cache whatever else there is.
