*''Plug and Play:'' If a hardware expansion is connected to the CPC FutureOS will automatically detect that expansion, initialise it and make it available to user and applications. The architecture of the OS allows you to add and remove hardware on purpose (hot plug and play). You can switch external hardware on or off in the configuration bytes (use ConfigOS utility).
== Usage of memory Memory Management ==
The OS uses only small amounts of the memory of the CPC since it is located and executed in ROM. When using the Desktop the OS uses the RAM between &A000 and &BFFF (8 KB). In case an application is running the RAM that is used by the OS can be reduced to the region between &B800 and &BFFF, in this case only 2 KB are occupied by system variables of the OS. Depending on the amount of active drives and HD partitions additonal expansion RAM blocks will be occupied for directory buffering, but there is no reduction in free main memory (first 64 KB).
