（一）查看ramdisk的内容
注：首先需要把ramdisk的扩展名更改为.gz，然后解压
bash$ su 
Password : 
bash$ mkdir /mnt/your_ramdisk_directory 
bash$ mount -o loop your_ramdisk /mnt/your_ramdisk_directory 

Now "your_ramdisk" is mounted and you can access it like this : 
bash$ cd /mnt/your_ramdisk_directory 

（二）修改
You can set up your network interfaces automaticaly at start time just by adding a small file in /etc/rc.d/init.d. we named it interfaces. this file contains the following line : 
ifconfig eth0 ip_address 
what you need to do next is to create a symbolic link to the file interfaces in /etc/rc.d/rc3.d, it goes like this : 
bash$ cd /etc/rc.d/rc3.d 
bash$ ln -s ../init.d/interfaces S20interfaces 


（三）修改完毕
bash$ cd  where_your_ramdisk_file_is 
bash$ umount /mnt/your_ramdisk_directory 
bash$ gzip -c -v9 ramdisk > /tftpboot/ramdisk
