# 2.10.使用 Live CD

bsdinstall 的欢迎菜单（见[欢迎菜单](https://docs.freebsd.org/en/books/handbook/bsdinstall/#bsdinstall-choose-mode)提供了选项 **Live CD**。这对那些仍在考虑 FreeBSD 是否适合自己的用户很有帮助，他们可以在安装之前测试一些功能。

在使用 **Live CD** 前应注意以下几点：

* 使用系统需要身份验证。用户名为 `root`，密码为空。
* 由于系统直接从安装介质运行，性能将明显弱于安装在硬盘上的系统。
* 此功能仅提供命令提示符，未提供图形界面。
