    2020* Classrooms: This option will add objects as computers, group and perform operations on them. 
    2121* Actions: This option will manage the actions for apply or to program to the computers.
    22 * Images: This option will allow Esta opción nos permite gestionar la información de los objetos imágenes. - NOTA: antes de crear cualquier imagen, se ha de definir previamente desde esta opción.
     22* Images: This option will allow manage the information of the images. NOTE: It is necessary define this option before to create any image.
    2323* Hardware: From this option, we can manage the hardware of the organizational unit.
    2424* Software: From this option, we can see the software list of our images.
    … …  
    5252       - seeder:  mode working distributed where a Master client is serving an image.
    5353   - P2P time (seconds) as seeder: Whatever of the working mode of the P2P client for downloading, we can define that once you have the whole image in the cache partition, it is dedicated "X" seconds to share it to other clients.
    54 - '''Protocolo Multicast.'''
    55   - ''multicast:''   with two options: full-duplex and half-duplex  (use full-duplex) 
    56   - ''ip multicast'': multicast direction for this classroom:   239.194.x.z   where x is the second octet of the IP network of the classroomm, and z is the third octet. e.g. If the IP direction of aula_virtual_1 is 172.17.36.0, the IP multicast corresponds: 239.194.17.36. In the case of our network has two classrooms and we need to use simultaneous multicast, we should assign the IP multicast of 239.194.17.37.
     54- '''Multicast Protocol'''
     55  - ''multicast:''   with two options: full-duplex and half-duplex  (it is recommended to use full-duplex) 
     56  - ''ip multicast'': multicast direction for this classroom:   239.194.x.z   where x is the second octet of the IP network of the classroomm, and z is the third octet. e.g. If the IP direction of virtual_classroom_1 is 172.17.36.0, the IP multicast corresponds: 239.194.17.36. In the case of our network has two classrooms and we need to use simultaneous multicast, we should assign the IP multicast of 239.194.17.37.
    5757  - ''port:'' it is the port, where the computer sends by multicast, sincronized with the computers. Values may be even from 9000, e.g.: 9000, 9002, 9004, 9006 ..... Preferely, you should use 9000, and in the case of ip multicast, if we have two classroom in the same network, you should assign the first classroom to the port 9000 and the second to 9002.
    5858  - ''speed:'' It is the maximum speed in Mbits/second. The maximum value allowed by the clone motor is 90 mbits - there are test with gigabits with excellent results.

    102102== Booting of OpenGnSys clients ==
    103103* The web application of !OpenGnSys manages the boot of computer registered on it.
    104 * A computer manages by !OpenGnSys will show a pxe menu at boot time by default. Users can choose between two boot types. The first one will boot from hard disk (default option) and the second one will boot from PXE (with the operating system that handles the deployment).
     104* A computer manages by !OpenGnSys will show a PXE menu at boot time by default. Users can choose between two boot types. The first one will boot from hard disk (default option) and the second one from PXE (with the operating system that handles the deployment).
    105105
    106106* This type of booting should (must) be modified for working in native mode with !OpenGnSys.
    … …  
    117117The differents elements offered by the boot loader are:
    118118* ogclient  - PXE client of !OpenGnSys without administration console, and with read-only access to the Repository.
    119 * ogclient-admin - PXE xlient of !OpenGnSys, with administration console, and with write access to the Repository. It is set to perform a boot process in debug mode which informs the administrator about the process and provide access points to the shell for debugging.
    120 * mbr 1hd  - The computer always boots by the boot loader defined in MBR of the first hard disk.
     119* ogclient-admin - PXE client of !OpenGnSys, with administration console, and with write access to the Repository. It is set to perform a boot process in debug mode which informs the administrator about the process and provide access points to the shell for debugging.
     120* mbr 1hd  - The computer always boots by the bootloader defined in MBR of the first hard disk.
    121121* 1hd 1partition  - If exists a boot loader installed, the computer boots from this partition.
    122122* 1hd 2partition - If exists a boot loader installed, the computer boots from this partition.
