If you wish to try out PC-BSD® before installing it, download either the live DVD or live USB version. Once you have burned the downloaded file to the appropriate media, insert the DVD or USB device.

(Sorry for the inconvenience)

Beginning with PC-BSD® 9.1, Live Mode is a read-write live image that is only available for USB media. The uncompressed live image is about 4GB in size, but 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.

NOTE: the speed of Live Mode is dependent upon the quality of the USB device. If you are purchasing a device, look for one that is advertised as "high speed".

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 followed by the PC-BSD® graphical boot menu, shown in Figure 2.6a.

The options in this menu are described in Booting Into PC-BSD®. If you press enter or wait 10 seconds, the system will continue to boot. If this is the first time you have booted into the image, the boot will pause with this message:

Trying to mount root from ufs:mdo []...
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:

Resizing file-system da0a on da0, this may take a few minutes...
Adjusting partition tables on da0...
Running growfs on da0a, this may take a while...
Cleaning up...
Rebooting...

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 Logging In screen.

When logging in, use the user account and password that you were prompted to create. Three desktops are available: Fluxbox, LXDE, and Openbox.
