Change: For DMA
Shared Memory:
- Allow to allocate on the kernel memory, becouse ISA-DMA can use only memory of the low and physical address.
  I NOT decide yet that DMA use a kernel memory or a shared memory.
Kernel:
- ISA-DMA is provide user-processes throgh the system-call. It is same reason too.
- Has shorter initial message.
