最近想玩玩自己编译内核，当然也就想精简一下，只需把自己硬件的驱动编译进内核就行了，想

ATI的芯片组，8139的网卡，其它看不出什么，查看一下现在系统装入了那些模块，lsmod 。

谢谢楼上的热心帮助。

AutoXBC

内核模块名字有用。

d00m3d

一般是把必要的文件系统及硬件（如 SATA)支援编入内核，不要编译成模块

另外要注意不能随便删除 SCSI 支援，否则现在很多被模拟成 SCSI 设备的周边如 U 盘之类会无法使用

我把很多没见过的硬件驱动都给删除了，呵呵，结果开机不了了，声音等还不知道呢。这几天已经编译了N次了。

最简内核＋硬盘驱动的配置，可参考：http://linuxman.blog.ccidnet.com ... -itemid-293122.html

还是那句老话，“生命的乐趣在于折腾”，内核配置的增增减减，其乐无穷啊！

占硬盘空间少些，实际的性能并不会因为精简而快了。

编译了这次内核后，我发现我对自己电脑的硬件了解了很多！

这个当然了，每次新内核出了，我都会全部浏览一次，但多数会选齐所有可能的东西。特别是usb设备，我一定全编M；文件系统、防火墙等软件上的选项都一定全编M。
