装solaris 9 for x86时出错了！！

[weixin_38054680]

错误信息如下：

error: Configuration error - missing controller?

The root filesystem is not mounted and the configuration assistant hat exited prematurely. Booting is unlikely to succeed .CTL-ALT-DEL
may be used to reset the machine.

Failover to boot interpreter - type ctrl-d to resume boot

这是为什么？？
