(Sorry for the inconvenience)



The installation file for PC-BSD® can be downloaded for free and ends with an .iso file extension. This file can either be burned to a DVD media or written to a removable USB device. This section demonstrates how to verify the downloaded file's checksum. The next section will demonstrate how to burn the file to bootable media. You can install additional components and applications after the installation using Package Manager and AppCafe®.

If you have a slow download connection or wish to support the PC-BSD® project financially, you can purchase PC-BSD® DVDs from the FreeBSD Mall[1].

Members of the PC-BSD® project attend many IT conferences across the globe and give out PC-BSD® DVDs at conference booths. Visiting a PC-BSD® booth is an excellent way to meet other PC-BSD® users and to get your questions answered. Check the PC-BSD® Blog[2] to see if any events are happening near you. If you are organizing a PC-BSD® booth, contact us[3] to arrange for DVDs.

Data Integrity Check

After downloading the .iso file, it is a good idea to check that the file is exactly the same as the one on the PC-BSD® server. While downloading, a portion of the file may get damaged or lost, making the installation file unusable. Each

PC-BSD® download has an associated MD5 checksum which is listed next to the download link. If the checksum of the file you downloaded has the same number, your download was successful. If the MD5 numbers do not match, try downloading the file again. In order to verify the checksum, you will need to use a checksum verification utility.

If you are currently using a Windows system, you can download and install the FastSum[4] utility. Once installed, launch the program and click the "Files" button, shown in Figure 2.4a, to browse to the location of your downloaded file.

Once the file is selected, click the green arrow to calculate the checksum. Once calculated, it will be listed in the "Checksum\State" column, though FastSum will capitalize the letters.

On Linux and BSD systems you can use the built-in md5 (or md5sum) command line tool to check the data integrity of the downloaded file. In this example, the file is located in the Downloads subdirectory. You should substitute the name and location of the file that you downloaded:
