Re: Boot with NFS on MIPS32

I believe you need to enable "Kernel level autoconfiguration" which is 
under Networking->Networking support->Networking options->TCP/IP 
networking (IP_PNP), and then you'll have a "Root file system on NFS" 
option (ROOT_NFS) available under Network File Systems.

Hi All,

I have one MIPS32 embedded system with Linux Kernel 2.6.23.17. Right
now, I have problem to boot from NFS. The NFS server works fine. I am
able to mount the directory from anther Linux work station. I attach
the .config file, there maybe some config flags I forget to open.

Thanks for your help,

Mike
