 u-boot 启动内核出现 Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)

我已经按照《嵌入式LINUX应用开始完全手册》中的LINUX内核移植章节中的介绍的方法，用书中的提供的补丁对
内核打了补丁，也按照书中说的增加了对YAFFS文件系统的支持，编译下到MINI2440 启动后，还是出现了
。。。。。。。。

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)
的错误。
查了一些资料，有人说要在make menuconfig 的时候增加对 ramdisk   和 initrd 支持，
但是我不知道ramdisk   和 initrd 在内核配置选项的那个选项下。
有那位大哥碰到过类似的问题或是知道这么解决这个问题，望指教，谢谢！
（我是在虚拟机中安装的LINUX下编译的）
