Live Session


Cos'è un sistema Live

A live CD is a CD containing a bootable computer operating system. Live CDs are able to start a complete, and modern operating system on a computer disregarding the presence of another storage device, such as internal hard drive. Live USB devices are similar to live CDs, but often have the ability to write the changes, and contents within the same device.
While a live CD typically doesn't alter the operating system or files already on your hard disk, many live CDs include mechanisms and utilities for altering the internal disk, including the system installation. This is important for some management aspects of the installed system, such as removing viruses, make a copy of the hard drive to recover the damaged systems.

The default option is that, once the live CD is ejected, and PC rebooted, the system installed on the computer will be intact and unchanged. You can start the system completely without permanent installation, by placing the files and the necessary objects, rather than on the hard disk, into RAM. This, however, means that the available RAM to launch applications is scarce, invalidating the system usability or slowing down the system performances.

liveVoyager is a live CD and provide the opportunity to be tested prior to its installation.

Using liveVoyager Live

To start the liveVoyager Live session, simply insert the CD into the drive and restart the PC. Currently all PCs have BIOS boot sequence configured to start from the CD-ROM. If this configuration is not available, it is necessary to configure the BIOS to this need.

BIOS Set-up

To access the BIOS of the motherboard, simply press the "Delete" button in the first few moments after the PC start. If "Delete" is not running, you can press F1 or F2.
Once in the BIOS text screen you need to find section that shows the devices with which you start your PC, and follow the on-screen instructions that show how to change the parameters, how to save and how to exit the BIOS.

Boot options

Once you sure that PC will boot from the DVD, just restart it with the liveVoyager disk in the drive, and wait until you see the liveVoyager boot screen. Usually just press the Enter key to start the load, otherwise expect the default ten seconds to see the system boot itself.

Testing on performance and hardware compatibility

liveVoyager Live is an operating system able to run on a vast number of machines and hardware, but not all. Live function allows you to perform tests to determine whether your own machine is able to run a Linux operating system.
Starting liveVoyager in live session you can check if motherboard, processor, RAM, graphics card, network card, wifi card, and various devices are supported by the system.
If the system shows the desktop to the correct screen resolution, it means that the motherboard, processor, RAM and graphics card were properly recognized and configured.
If run music player, sounds are perceived correctly, it means that the sound card was recognized and configured properly (to make adequate proof, it is appropriate to insert a USB with some songs in a USB port of your computer and start the media player to listen to the tracks in the USB stick. If playback is successful, you will be sure having a sound card and the USB controller supported).
liveVoyager Live also allows you to launch DSL, analog, wifi, and mobile connection. Simply test it, to see if the network card is supported. Usually an ethernet DSL modem is always supported, while USB modem can often be unsupported. Wifi connections may rarely present difficulties.

Evaluate distribution equipment, and look'n feel

liveVoyager Live is an operating system richly equipped with a modern and beautiful software. However, you may be looking for a system with other software and with a different look and feel. Starting liveVoyager in Live session allows you to check if software equipment is that you want, and how to expand it. In this regard, we suggest you to see this section.

Using a portable system

liveVoyager Live is a great portable system can work very well on almost any type of computer. So if you want to work with liveVoyager even on different computers, just having a liveVoyager DVD, and start it.
Its architecture, the available graphical environment, and the deep optimization, enabling the system to start in just two minutes, offering good software for your needs, leaving the PC unchanged once liveVoyager is turned off.
The ideal condition to use liveVoyager Live DVD in any occasion, and on any machine, is to have the liveVoyager DVD with a USB memory containing data and files you want to have. Once the system is loaded, insert the USB memory, and you can work in your preferred environment, on desired files, completely safe, and without trace.
This approach is particularly suitable when the machine is not able to support the direct boot from USB memory sticks.

Limits of Live version

The Live version of liveVoyager, like most of the Live systems, has limits that can not be remedied. First of all, the live system does not allow the permanent storage of changes to files and settings. You can remedy this only with the use of USB sticks with the operating system in it. Unfortunately not all computer support the boot from USB sticks.

Secondly, the live version, going from the DVD, requires that for any function it is necessary to restart the disk, with undeniable performances slowdown. If the application is heavy, the latency time grows. Run a simple text editor or terminal has a low latency, but a web browser require much more resources, and latency is evident.

You must remember, finally, that if the machine has available a single CD-ROM, this unit will not be available to burn, listen to audio CDs or to back up the system, as is keeping liveVoyager "alive".

liveVoyager offers its best only when it is installed on your computer.
