Live Mode is a read-write live image that is only available for USB media. It is meant to be a portable version of PC-BSD®, similar to an operating system on a stick. The uncompressed live image requires a USB device that is at least 8GB in size. However, you will want to write it to a USB device that will provide sufficient room for the files that you wish to save and any applications that you wish to install.
To use PC-BSD® Live Mode, download the live USB version. Once you have written the image file to a USB media, boot the system with the USB device inserted. Assuming your BIOS has been set to boot from that device, you should see some startup messages. The first time you boot the image, the boot process will pause with this message:
tput: no terminal type specified and no TERM environmental variable. Do you want to expand the file-system for this LIVE media? This process may take up to 15 minutes.Resize? (y/n):
This step grows the filesystem so that it can use the entire capacity of the USB device. Press y to expand the filesystem and reboot into live mode:

You will know that you have successfully entered live mode when you are asked to accept the graphics resolution mode that is considered to be optimal for your hardware.
If this is your first boot, you will then proceed through the post-installation configuration screens, ending in the Anmeldung screen. When logging in, use the user account and password that you were prompted to create. Three desktops are available: Fluxbox, LXDE, and Openbox.
