ln -s /root/WOWOTOKERNEL


#gedit WOWOTOKERNEL



  1. 移除不必要的网络卡驱动程序。
  2. 移除不必要的 SCSI 装置。但不要移除 scbus、ch、da 等项目。
  3. 移除不必要的 IDE 装置,如 IDE 软盘。
  4. 如果您不使用 USB,也可以将 USB 装置移除。
  5. save!
#

# cd /usr/src/sys/i386/conf#





# config WOWOTOKERNEL






#如果您想要知道您修改过什么,可以使用下列指令来看二个档案的差异:

# diff -ub GENERIC MYKERNEL

#cd ../compile/WOWOTOKERNEL


#
make cleandepend


#
make depend


#make

#make install


cd /



# rm -rf /usr/src/sys/i386/compile/



WOWOTOKERNEL

#sync

#sync

#sync



#reboot

#can't boot correctly ?

#fress 6 ! load kernel yourself

#unload

# boot /boot/kernel.old



7、如果系统正常,清理垃圾文件

cd /usr/src

make clean cleandir






#如果使用的是 FreeBSD 5.x 以后,请在看到开机选单时按 6 以进入 loader 模式,并输入下列指令以使用旧的 kernel 开机:

OK unload

OK boot /boot/kernel.old

#FreeBSD 5.x 后的 kernel 放在 /boot/kernel 目录下,而旧的核心在 /boot/kernel.old
