Writing an IMG File to Flash media
If you selected to download a "Boot only USB for network & internet installs" .img file, you can write the image file to a flash card or removable USB drive using the built-in dd command line utility on a BSD or Linux command system. On a FreeBSD system, the superuser can use this command to write the specified image in the current directory to the first plugged in USB device:
dd if=PCBSD8.1-x86-USB-bootonly.img of=/dev/da0 bs=5k
When using the dd command:
- if= refers to the input file; in our case, the name of the file to be written
- of= refers to the output file; in our case, the device name of the flash card or removable USB drive
- bs= refers to the block size
The device name will be different on a Linux system. To determine your device name:
To burn the image on a Windows system, you can use the physdiskwrite graphical utility.
NOTE: The USB images are FreeBSD-UFS formatted, and will not show up as a viewable file-system under Windows.
