FreeBSD 8.1-RELEASE is now available for the amd64, i386, ia64, pc98, powerpc, and
FreeBSD 8.1 can be installed from bootable ISO images or over the network. Some
architectures (currently amd64 and i386) also support installing from a USB memory stick.
The required files can be downloaded via FTP or BitTorrent as described in the sections
below. While some of the smaller FTP mirrors may not carry all architectures, they will
all generally contain the more common ones such as amd64 and i386.
MD5 and SHA256 hashes for the release ISO images are included at the bottom of this
The purpose of the images provided as part of the release are as follows:
- This contains everything necessary to install the base FreeBSD operating system, a
collection of pre-built packages, and the documentation. It also supports booting into a
“livefs” based rescue mode. This should be all you need if you can burn and use DVD-sized
- This contains the base FreeBSD operating system and the documentation packages for
CDROM-sized media. There are no other packages.
- This contains support for booting into a “livefs” based rescue mode but does not
support doing an install from the CD itself. It is meant to help rescue an existing
system but could be used to do a network based install if necessary.
- This supports booting a machine using the CDROM drive but does not contain the support
for installing FreeBSD from the CD itself. You would need to perform a network based
install (e.g. from an FTP server) after booting from the CD.
- This can be written to an USB memory stick (flash drive) and used to do an install on
machines capable of booting off USB drives. It also supports booting into a “livefs”
based rescue mode. The documentation packages are provided but no other packages.
As one example of how to use the memstick image, assuming the USB drive appears as
/dev/da0 on your machine something like this should work:
# dd if=8.1-RELEASE-amd64-memstick.img of=/dev/da0 bs=10240 conv=sync
Be careful to make sure you get the target (of=) correct.
FreeBSD 8.1-RELEASE can also be purchased on CD-ROM or DVD from several vendors.
