before 然后我就重启, do u run lilo to make u modification effective?
u need run lilo after modifying lilo.conf, but need not run grub after u modifying grub.conf.
-v is to give u more msg. lilo is enough.
but u had better add an entry instead of modifying an entry. once u new kernel fails to boot up, u still can use old one to boot.
be sure to enter u new option name when u see lilo: otherwise it still uses the default one, which usually is u old kernel.
