谢谢指导，有进步，但是又出现了新的问题
系统引导时输出

root （hd0，0，a）
filesystem type is ffs ,partion type 0xa5
kernel /boot/loader
[FreeBSD-a.out, ..........]

FreeBSD/i386 boot strap loader,Revision 0.8
hit [Enter] to boot immdialy ,or any other key for command prompt

can't load 'kernel'
can't load 'kernel.old'

眼看就要成功了，唉！我装完bsd时，特意进了系统，没问题，kernel文件肯定在，是不是文件系统的类型不对，望大虾们指教！！
