msft penalizes oems for selling OS-less pcs..

but preload linux and the oem gets a support headache.... very
difficult for the enduser to remove that linux partiton so windows can
be loaded..

so just preload dos and geos.. endusers can buy and install their
own retail (resellable on ebay) windows easily on the already existing
dos/geos partition..
