[新手]不会用U盘!

ltao

插上U盘什么反应也没有。
/dev下也没有da0的设备。
我试着带着U盘启动系统，结果
到下面红色字的地方停止了好长时间。我以为死机了，结果拨下U盘又继续启动。
麻烦大家给看看。
谢谢

启动好后再插入U盘, 上面会显示U盘的信息, 如果/DEV/下没有设备号, 自己建一个, 然后disklabel 查看一下U盘上的分区号及文件类型!

congli

把mykernel内核配置文件贴出来看看.

ltao

版主好!
偶先声明:偶真的是刚接触Freebsd7、8 天的初学者.其它类unix以前也没接触过.
问题1、

启动好后再插入U盘, 上面会显示U盘的信息

您指的上面是在控制台，还是桌面环境下?而且这两种状态下我都试过，没有任何反应。
问题2、

如果/DEV/下没有设备号, 自己建一个

怎样建立一个设备号
问题3、

然后disklabel 查看一下U盘上的分区号及文件类型

这个操作是不是要将U盘mount上之后才可以?
谢谢回答![/quote]

内核文件我就加了一个声卡驱动，其它没动!
