Try changing the following and try again. I realize that you advised you
didn't think you had a problem at this layer, but I have seen settings such
as yours fail to complete the bootp download of the install kernel.
change
1.Gateway to be equal to the NIM server since you are on the same subnet
2. 100,full duplex from auto if on enet switch
100,half duplex if on hub
