How is eth0 config?

Hi,

Could some one explain to me how CONFIG_IP_PNP is used to configure eth0 and
lo briefly? Ie what config files are used and when ? just basics would be
perfect (even a URL)...

I currently am having problems with my eth0 being configure in one image but
not the other (with the same kernel which has CONFIG_IP_PNP configured and a
good bootline (below)).

Thanks as always,
Jim

Ps

bootargs root=/dev/ram rw
ip=$(ipaddr):$(serverip):$(gatewayip):$(netmask):$(hostname)::off
console=ttyS0;bootm 0x2900000 0x2A00000
