Computer-based Simulation of Vegetation. Development of a Cellular Automata Model for Grasslands

Of course, after the bootloader has performed this basic processor and platform initialization, its primary role becomes booting a full-blown operating system. It is responsible for locating, loading, and passing execution to the primary operating system. In addition, the bootloader might have advanced features, such as the capability to validate an OS image, the capability to upgrade itself or an OS image, and the capability to choose from among several OS images based on a developer-defined policy. Unlike the traditional PC-BIOS model, when the OS takes control, the bootloader is overwritten and ceases to exist.[56] 7.2. Bootloader Challenges Even a simple "Hello World" program written in C requires significant hardware and software resources. The application developer does not need to know or care much about these details because the C runtime environment transparently provides this infrastructure. A bootloader developer has no such luxury. Every resource that a bootloader requires must be carefully initialized and allocated before it is used ...»
