What's New
The Windows 2000 Professional installation and upgrade procedures have been enhanced from previous versions of the operating system. The following is a brief description of these enhancements.Support for Plug and Play DevicesMicrosoft® Windows® 2000 now supports Plug and Play technology. A Plug and Play system requires the interaction of the operating system, basic input/output system (BIOS), devices, and device drivers. Windows 2000 Plug and Play is an enhanced implementation which extends the existing Microsoft® Windows NT® version 4.0 input/output (I/O) structure to support Plug and Play and power management. For more information about Plug and Play, see "Device Management" in this book.Compatibility Check OptionsWindows 2000 Professional Setup comes with a compatibility-mode option that can be used before installing Windows 2000 Professional to examine hardware and software for known problems that might be encountered during the Setup process. It creates a report to determine which hardware files and any upgrade packs are needed to successfully run Windows 2000. This report can be sent to a printer or saved to a file for later review. You can also get a downloadable version of this compatibility check option by using the Windows 2000 Readiness Analyzer link on the Windows 2000 Web Resources Page at: http://windows.microsoft.com/windows2000/reskit/webresources.
