21 Jul 1995TL;DR: In this paper, the authors propose a method for interfacing an application program with an operating system of a computer when the application program relies on a predetermined address line to be set in a low state during the initial stages of the application's operation.
Abstract: A method for interfacing an application program with an operating system of a computer when the application program relies on a predetermined address line to be set in a low state during the initial stages of the application program's operation. The computer has a lower memory region, which is addressable when the predetermined address line is in a low state, and an upper memory region, which is addressable when the predetermined address line is in a high state. The method provides an operating system stub in the lower memory region of the computer and provides an operating system in the higher memory region of the computer. The stub receives each operating system call made by the application program. After receiving an operating system call, the operating system stub sets the predetermined address line to the high state if the predetermined address line is in the low state then invokes the operating system call. Upon return from the operating system call, the stub determines whether the application program has made more than a predetermined number of operating system calls. If the application program has not made more than a predetermined number of operating system calls, the stub resets the predetermined address line to the low state.

TL;DR: In this article, a partition is formed within a computer-readable medium and information is formed that identifies a logical drive associated with the partition which may be used irrespective of whether execution of the operating system software is reinitiated.
Abstract: Execution is initiated of operating system software by a computer system. After initiating execution of the operating system software, a partition is formed within a computer-readable medium. In response to the partition, information is formed that identifies a logical drive associated with the partition which may be used irrespective of whether execution of the operating system software is reinitiated. This information may be formed in extended memory, the high memory area, or the highest addressable space of conventional memory.
