Sounds like bull shit to me from another worthless site admin/writer looking for hits. I just bought a GF-4 MX 64meg card and nothing this says is true in Windows ME or XP. It shows up as 64 megs on boot up and 64 megs in Windows and there is no RSCMPT file running.
Sounds like an incompatibility with Win2000 and the RSCMPT is a work around.
Also on the 4 chip deal, maybe check the other side of the card for the other 4 chips.
