The very last thing in the <acronym>POST</acronym> is the <literal>INT 0x19</literal> instruction. The <literal>INT 0x19</literal> handler reads 512 bytes from the first sector of boot device into the memory at address <literal>0x7c00</literal>. The term <emphasis>first sector</emphasis> originates from hard drive architecture, where the magnetic plate is divided into a number of cylindrical tracks. Tracks are numbered, and every track is divided into a number (usually 64) of sectors. Track numbers start at 0, but sector numbers start from 1. Track 0 is the outermost on the magnetic plate, and sector 1, the first sector, has a special purpose. It is also called the <acronym>MBR</acronym>, or Master Boot Record. The remaining sectors on the first track are never used.
POST的最后一步是执行<literal>INT 0x19</literal>指令。 这个指令从引导设备第一个扇区读取512字节,装入地址<literal>0x7c00</literal>。 <emphasis>第一个扇区</emphasis>的说法最早起源于硬盘的结构,硬盘面被分为若干圆柱形轨道。给轨道编号,同时又将轨道分为 一定数目(通常是64)的扇形。0号轨道是硬盘的最外圈,1号扇区, 第一个扇区(轨道、柱面都从0开始编号,而扇区从1开始编号) 有着特殊的作用,它又被称为主引导记录(Master Boot Record, <acronym>MBR</acronym>)。 第一轨剩余的扇区常常不使用<_:footnote-1/>。

On most <trademark class="registered">UNIX</trademark> systems, <literal>root</literal> has omnipotent power. This promotes insecurity. If an attacker gained <literal>root</literal> on a system, he would have every function at his fingertips. In FreeBSD there are sysctls which dilute the power of <literal>root</literal>, in order to minimize the damage caused by an attacker. Specifically, one of these functions is called <literal>secure levels</literal>. Similarly, another function which is present from FreeBSD 4.0 and onward, is a utility called <citerefentry><refentrytitle>jail</refentrytitle><manvolnum>8</manvolnum></citerefentry>. <application>Jail</application> chroots an environment and sets certain restrictions on processes which are forked within the <application>jail</application>. For example, a jailed process cannot affect processes outside the <application>jail</application>, utilize certain system calls, or inflict any damage on the host environment.
在大多数<trademark class="registered">UNIX</trademark> 系统中,用户<literal>root</literal>是万能的。这也就增加了许多危险。如果一个攻击者获得了一个系统中的<literal>root</literal>,就可以在他的指尖掌握系统中所有的功能。在FreeBSD里,有一些sysctl项削弱了<literal>root</literal>的权限,这样就可以将攻击者造成的损害减小到最低限度。这些安全功能中,有一种叫安全级别。另一种在FreeBSD 4.0及以后版本中提供的安全功能,就是 <citerefentry><refentrytitle>jail</refentrytitle><manvolnum>8</manvolnum></citerefentry>。<application>Jail</application>将一个运行环境的文件树根切换到某一特定位置,并且对这样环境中叉分生成的进程做出限制。例如,一个被监禁的进程不能影响这个<application>jail</application>之外的进程、不能使用一些特定的系统调用,也就不能对主计算机造成破坏。

An atomically protected variable is a special variable that is not protected by an explicit lock. Instead, all data accesses to the variables use special atomic operations as described in <citerefentry><refentrytitle>atomic</refentrytitle><manvolnum>9</manvolnum></citerefentry>. Very few variables are treated this way, although other synchronization primitives such as mutexes are implemented with atomically protected variables.
原子保护变量并非由一个显在的锁保护的特殊变量,而是:对这些变量的所有数据访问都要使用特殊的原子操作</refentrytitle><manvolnum>9</manvolnum></citerefentry>。尽管其它的基本同步机制(例如mutex)就是用原子保护变量实现的,但是很少有变量直接使用这种处理方式.
