各位大师！

我用mini2440开发板挂载nfs的文件系统，内核打印信息提示“IP-Config: Device `eth0' not found”，我的nfs服务无法完成

一下是我的网络配置

u-boot里配置--

#define CONFIG_BOOTARGS        "console=ttySAC0 root=/dev/nfs nfsroot=192.168.0.101:/opt/s3c2440/root_nfs  ip=192.168.0.99:192.168.0.101:192.168.0.1:255.255.255.0:www.sansung.com:eth0:off"

我的windons网络 192.168.1.70    255.255.255.0 192.168.1.1  dns = 192.168.1.1

我的linux网络     192.168.1.101 255.255.255.0 192.168.1.1  dns = 192.168.1.1
