Downloading Image

[Jin Cheng]

Hi,

I used ELDK ppc_4xx toolchain to compile a kernel from the same source as Aman.
I followed the arch/ppc/configs/ebony_defconfig and get a kernel.

Then I used the OpenBIOS to load that kernel. it is loaded fine, but the kernel
always
times out on "Sending BOOTP request..."

I used other machine to test my nfs server, it works fine.

Following is the screen out, Could you give me advice on the problem? Thanks.

Regards,

Jin Cheng
