nfs启动错误了

VFS: Unable to mount root fs via NFS, trying floppy.
VFS: Cannot open root device "nfs" or unknown-block(2,0)
Please append a correct "root=" boot option; here are the available partitions:
1f00             384 mtdblock0 (driver?)
1f01            2048 mtdblock1 (driver?)
1f02          128640 mtdblock2 (driver?)
1f03          131072 mtdblock3 (driver?)
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)
不懂为什么现在开启会出现这样的错误

1. 你可以在论坛里搜索"Cannot open root device "nfs";
2. 如果你想要别人帮忙，贴出完整的启动信息。
