We have been developing and implementing a prototype for running multiple operating systems on a single computer. This method improves the virtual machine method's problem that has dependence of child operating systems on their mother VM. This paper describes how to boot up multiple operating systems and how to switch operating systems from one to another. Under this method, physical memory is exclusively divided and reserved for each operating system from beginning and the trigger of switching is hardware interrupts which have no dependence on any operating system.

Due to the domestic growth of average PCs. virtual machine software for running multiple operating systems on a single system has become popular, today. Existing visual machine softwares are built on the similar concept of the conventional VM, which has dependence of child operating systems on their mother VM. This fact causes some problems such as performance limitation and collective security. In other works, accidental stop of the mother operating system leads to the corruption of the whole family. We have been research on the new formwork for solving these problems. As a key technology of the formwork, This paper describes a method for switching operating system from one to another safely. Under the method, the trigger of switching is a hardware interrput which has no dependence on any operating system. Also we propose 3 method for sharing hardware resource among the coexistent operating systems.

We haw been developing a method for running multiple operating systems on a single computer for utilizing their individual application programs effectively. This paper describes how to boot up multiple operating systems safely in succession by sharing physical memory among them. Under the method physical memory is exclusively divided and reserved for each operating system from beginning. Each operating system is controlled to boot up using their own memory region without having any bad effect on other operating systems.

We usually produce many documents during software development, which are supposed to be referred in the maintenance phase. Reusability of the documents is important. Therefore, an electronic document management system is developed. In this paper, we describe the new electronic document management system which has an e-mail interface for document registration. Thereby, we can manage many types of documents effectively such as design, specifications, minutes or discussions in meetings. In this system, user can easily register his documents to the system. All he have to do is simply sending an e-mail which has the documents as attachments. Therefore, the time and effort of registration decreases very much, and can share information effectively.

Personal computer (PC) is one of the fastest growing specialty in industry. Various kinds of I/O devices, application software packages (AP) and OSs are available under PC. Therefore, sometimes, we have a problem to find a good combination of devices, APs and an OS. To solve the problem, we need to run multiple OSs at the same time. In this paper, we describe a new technique to run multiple OSs in one box. We also illustrate some applications of this new technique. Our technique has three strong points - (1) no need to modify original OSs, (2) good I/O performance as bare OS, (3) no parent-child relationship among all OSs.
