引导freebsd时遇到错误 不知道怎么处理

reddavid

请问各位大大，这个错误是什么意思?
我的机器是atom是不是不兼容还是别的什么问题？
我用的是bootonly放在U盘里引导的

lsstarboy

应该是不支持，连内核都没读出来。

3. Open Issues

    FreeBSD/i386 10.0-RELEASE running as a guest operating system on VirtualBox can have a problem with disk I/O access. It depends on some specific hardware configuration and does not depend on a specific version of VirtualBox or host operating system.

    It causes various errors and makes FreeBSD quite unstable. Although the cause is still unclear, disabling unmapped I/O works as a workaround. To disable it, choose Escape to loader prompt in the boot menu and enter the following lines from loader( prompt, after an OK:

    set vfs.unmapped_buf_allowed=0
    boot

    Note that the following line has to be added to /boot/loader.conf after a boot. It disables unmapped I/O at every boot:

    vfs.unmapped_buf_allowed=0

也就是说 还是硬件不兼容喽  谢谢了

旧的32位凌动？

如果支持64，可以试试64的，另外你试试写个mfsbsd到U盘看看能不能启动

读取内核的过程出毛病，不会是磁盘有问题吧。。。。。

应该是U盘启动的问题。
如果是使用的是 MBR 分区模式的话，检查一下主引导记录和启动分区是否正确安装，启动分区要设为 active。

另外，启动分区中要有
/boot 文件夹，存放位置尽量靠前，
里面要有 /boot/kernel/kernel 内核文件及内核模块，大概 200多M
