Note To Microsoft Windows Users
Microsoft implemented a design change in Windows XP with Service Pack
2 (SP2) and Windows Vista. This change improves driver compatibility,
but however reduces the available memory compared to what is physically
insalled. For more information, please read the following article at Microsoft's
