Problemáticas del arranque en Pendrive en un sistema operativo didáctico.

The aim of this research project is to know about the involved details in the SODIUM operative system starting point from a USB flash support. On this investigation it is essential the structural analysis of the devices from a physical and a logical point of view. Base on this, we found differences among the technologies used for its construction and its internal functioning. The other thread of the exploration is based on the different types of BIOS and their influence on the boot. There is no available BIOS standard in the industry and, despite the fact that a common behavior is expected for all of them, each supplier can emphasize differences in the functioning. These two axes are the conductors of the entire research, together with the particular features of the development surroundings (as the Linux tools), and the SODIUM.
