Thinkpad 笔记本电脑上的 FreeBSD 内核

在这个wiki帖子中,公布了Thinkpad笔记本电脑上FreeBSD内核配置和一些基本的设置,目的是为了让更多的初学者能在最短的时间上手FreeBSD。FreeBSD是目前最好的免费OS之一,但愿它在开源之路上不断壮大。

在学习使用FreeBSD的过程中,我受益于网上众多的科普贴和坛子里朋友们的帮助。作为回馈,但愿我的这些小小的心得体会也能对他人有所帮助。

为什么选 Thinkpad?

FreeBSD 似乎比较青睐 Thinkpad, 提供了很多驱动和应用,例如 tpb 等。另外,在 /boot/loader.conf 里加入

acpi_video_load="YES"
acpi_ibm_load="YES"

就可以加载 acpi 支持。众所周知,FreeBSD 对 acpi 的支持一直是其诟病。可见 FreeBSD 对 Thinkpad 的“爱护”。当然,其他品牌的笔记本电脑,FreeBSD 也是相当支持的(我不是 Lenovo 的托儿)。我看 freebsd 对笔记本电脑的支持列表 http://laptop.bsdgroup.de/freebsd/,其中 Thinkpads 较多。而 FreeBSD 对 T42 的支持是 100%(不过休眠待机功能不work。。。)。所以,网上有人问买什么笔记本装 FreeBSD 最合适,一般的回答是 old Thinkpads of T, X, R series.

从做工上看,实话实说,现在的 Thinkpad 大不如从前了。Thinkpad T42 曾数次掉到地上,啥事也没有,捡起来接着用。2011 年底,我刚买了台 X220,看它的样子,我担心摔一次就彻底完蛋。不知 X220 能否像 T42 一样让我从来不为机器和操作系统担心,但愿事遂人愿。

FreeBSD 9.1 内核文件

为了初学者装机方便,我把我的Thinkpad笔记本电脑上的 FreeBSD 9.1 内核文件贴出来。该配置还在Thinkpad X61、X200上试验过,都是没问题的。

/boot/loader.conf 配置

有些硬件的驱动没有写入内核文件,而是通过模块引导,像无线网卡、蓝牙、SD卡等。X61的无线网卡是iwn,X200的无线网卡是ath,用户根据机器的具体情况改写下面的 /boot/loader.conf 配置。

#boot_verbose="-v"        # provide more dmesg information
autoboot_delay="1"        # Set wait time to 1 second
loader_logo="beastie"     # The color logo of FreeBSD

有关声卡的一点小注记

在 /boot/device.hints 里添加

后记

Thinkpad T42(CPU: Intel(R) Pentium(R) M processor 1.70GHz,内存 1G)是我的 workhorse,它是 IBM Thinkpad 被 Lenovo 收购前最后一批机器,我是 2005 年买的,一直用到2011年底才换掉。除了光驱和电池(只能坚持15分钟了)之外,一切都牛X如初。“好马配好鞍”,FreeBSD + T42 非常地争气,它们从来没让我失望过。有人把机器和 OS 看作玩具,有人把它们看作事业,而它们对于我就是养家糊口的工具(有点世俗……),我不知该用什么形容。

题外话:鸡肋是“食之无味,弃之可惜”,光驱连鸡肋都不如。在北美、欧洲,由于对媒体版权的保护,光驱还在残喘,一旦网络媒体发行发生革命,光驱就会被历史淘汰。平时,我几乎不用光驱。考虑到FreeBSD对硬件的支持的滞后性,以及USB安装已经成为FreeBSD的主流安装方式,我建议大家买不带光驱的二手笔记本电脑。当然,事先必须上网调查一下FreeBSD对该款电脑的硬件支持是否好,否则买了后悔。
