  • Method for generating an operating system by a static link-editor
    Patent number: 5136709
    Abstract: In an operating system generation method of a computer, a symbolic name is converted into an identification code, which is further converted into an address. This enables an inter-reference operation to be achieved between a kernel and input/output device drivers, thereby independently generating the input/output device drivers and the kernel. As a result, depending on the hardware configuration of the user system, input/output device drivers can be incorporated into the operating system.
