有部Olive以前设嘅root唔记得咗，于是做咗一次密码恢复。

1、开机，启动到呢个画面时：
FreeBSD/i386 bootstrap loader, Revision 0.8
(

, Tue Jun 17 01:31:38 GMT 2003)
Loading /boot/defaults/loader.conf
/kernel text=0x328787 data=0x26cb0+0x49fd0 syms=[0x4+0x3abc0+0x4+0x45468]
                    Loader Quick Help
                    -----------------
The boot order is PCMCIA or floppy -> Flash -> Disk -> Lan ->
back to PCMCIA or floppy. Typing reboot from the command prompt will
cycle through the boot devices. On some models, you can set the next
boot device using the nextboot command: nextboot compact-flash | disk
For more information, use the help command: help   
Hit [Enter] to boot immediately, or space bar for command prompt.

2、按空格进入ok模式，然后boot -s以单用户模式引导：
For more information, use the help command: help

3、引导到如下画面时，输入“/usr/libexec/ui/recovery-mode”作为shell：

Enter full pathname of shell or RETURN for /bin/sh: /usr/libexec/ui/recovery-mode
NOTE: to go to multi-user operation, exit the single-user shell (with ^D)

4、进入recovery-mode：
