The null drivers inactivate them so that nothing happens if a monitor or keyboard is plugged in. In addition, because Bus-Tech developers didn't want the noise or potential failure associated with having a hard disk in the system, they use a spindleless solid state memory device instead of a hard drive. The challenge was to fit both the Windows NT Embedded Runtime operating system and the application software on an 80-MB solid state memory device. We used it to drop out all the programs that aren't needed for a communications controller, such as a lot of the utilities, Notepad, the clock, the calculator, and even the Help files. Administrators can change the IP address that' s used for NetMeeting administration so that they can put the machine on their network and administer it remotely.
Developers can remove all the extraneous files and services in the operating system.
Using Target Designer, they can check dependencies to make sure that components required to make the system run aren't deleted. A headless system. The savings from quick development and reduced hardware costs are passed on to the customers. By using Windows NT Embedded, Bus-Tech was able to scale down the operating system to just the components necessary to support its Mainframe Appliance for Networking. This not only saved development time but also enabled Bus-Tech to build a headless system, which reduces hardware costs and ongoing administration.
