eth0 configuration

[Tang Nguyen]

Hi,

I think because in the kernel, you have configured IP:kernel level auto
configuration.  So, when the kernel boots up, it required correct IP address
and netmask to configure the eth0 interface.

If you turn off IP:kernel level auto configuration in Kernel Configure then
I think your old boot args should work.  But you need to configure IP
address for eth0 by command: ifconfig eth0 xxx.

Hi, thanks for the tip.
Using parameters: "root=/dev/ram0 rw ip=:::::eth0:", it works.
Could you explain me what it happens to start ip auto configuration when
this boot args is used?

With exactly the same boot arguments?

I have no idea why you load  a  binary  image  of  PPCBoot  when  you
already have PPCBoot running, but I hope you know hwat you are doing.

Try passing: "root=/dev/ram0 rw ip=:::::eth0:"

Or even "root=/dev/ram0 rw ip=:::::eth0:rarp"
