还执着于在PC上安装 MAC OS X 吗 不如试试 BSD 其实我们的选择有很多

This contains everything necessary to install the bbse FreeBSD operating system, a collection of pre-built packages, and the documentation. It also supports booting into a "livefs" bbsed rescue mode. This should be all you need if you can burn and use DVD-sized media.

一张DVD 完整的FreeBSD

This contains the bbse FreeBSD operating system and the documentation packages for CDROM-sized media. There are no other packages.

一张CD 基本的系统环境

This contains support for booting into a "livefs" bbsed 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 bbsed install if necessary.

LIVE 方式 用于恢复系统 + 网路安装 （如果各位童鞋有一个强大的网路支持的话 这是最适合的方式）

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 bbsed install (e.g. from an FTP server) after booting from the CD.

同上 不过只针对高阶用户

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" bbsed 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=8.0-RELEASE-amd64-memstick.img of=/dev/da0 bs=10240 conv=sync

Be careful to make sure you get the target (of=) correct.
