I am relatively new to this. I am trying to boot to an nfs root on my
PC RedHat 7.2 box. I downloaded the nfs image from ftp.mips.org
(nfsroot.mips.redhat7.1.eb-01.00.tar.gz). I have a working 2.4.3 kernel
that I have installed on a SGI. I need to boot to the nfs image so that
I can install to a local drive. I have setup nfs on my PC RedHat 7.2
box and it is working. When I boot the kernel on my SGI as follows:
>> boot nfsroot=192.168.0.75:mips ip=192.168.0.50
I get the following:

It seems that it initially finds the root on the nfs box but it never
get to do an init. It just stops and waits... Do I need to modify any
setting manually on my NFS image in order for the kernel to boot?
Thanks
