Abstract
A computer architecture having a main memory suitable for the storage of programs and data accessible within a predefined memory address space, a central processor capable of accessing the memory address space and a modified disk operating system program capable of execution from ROM or in a diskless environment. The operating system, upon execution by the processor, provides for the reservation of a first portion of the memory address space for support and application programs, preferably in a disk paradigm, a second portion for dynamic allocation and recovery by the operating system as necessary for the execution of support and application programs, and a third portion, located within said second portion, for the static storage, at predefined addresses, of the executable code segments of the support and application programs. Each support and application program includes an address reference to its corresponding executable code segment, in the third portion of the memory address space.
