You can leave the default value of ic_enable at 0 and enter ip=bootp as part of your boot prompt.

We have it working on 2.4.14-pre3. 1) You still need a command line with the nfs root directive 2) Your .config and autoconf.h need to specify both CONFIG_ROOT_NFS and CONFIG_IP_PNP_BOOTP. There may be a way to do it with command line options, but I just said the heck with it and changed net/ipv4/ipconfig.c to set the default value of ic_enable to 1. It used to be default 1, but now is default 0. -- David Wright, Consulting Engineer, InfiniSwitch Corp. > -----Original Message----- > From: Kenneth Johansson [mailto:kenneth.johansson at inn.ericsson.se] > Sent: Wednesday, November 07, 2001 12:39 PM > To: linuxppc-embedded at lists.linuxppc.org; akuster at mvista.com > Subject: Re: linuxppc_2_4_devel on walnut > > > > This is a litte update. > > I did indeed not use the default configuration.
