不同机器可能由于安装的磁盘分区不同而内容有所变化，不过基本信息大同小异，大家用得着的可以作为参考：

# grub.conf generated by anaconda

# Note that you do not have to rerun grub after making changes to this file

# NOTICE: You do not have a /boot partition. This means that

# all kernel and initrd paths are relative to /, eg.

# root (hd0,4)

# kernel /boot/vmlinuz-version ro root=/dev/sda4

# initrd /boot/initrd-[generic-]version.img

#boot=/dev/sda
