stands for Read Only File System and is used for accessing code on media that

cannot be executed on that media (otherwise known as non-execute in place

storage) e.g. NAND flash. </p> <p>It is also used by the composite file system

for presenting a single drive Z: to the file server regardless of the underlining

NAND flash technology being employed. </p> </section>

for e.g. NAND flash. To execute code on that media, the contents first have

to be loaded into RAM and then executed.</p> </section>
