Sorry for the re-post but not reponse !! I have FreeBSD 4.0-STABLE on i386, was -RELEASE ) What I am trying to do is nfs root boot from the loader (?) I do: ok> unload kernel ok> load diskless_kernel ok> set kernel=diskless_kernel ok> boot -r -h Now what I understand is the -r flag will tell the kernel to overide the rootdev and use the "staticly linked device" from when you made the kernel (this would be the BOOTP_NFSROOT option ?) Now my kernel (the diskless_kernel ) is a diskless kernel ( with BOOTP, NFS_ROOT .... etc.. ) compiled in. But when I boot like this is just tries to mount /dev/ad0s1a ... (normal device ) even though it gets the proper reply from the bootp server that its rootfs=<nfs mount> it even prints : rootfs is <my nfs mount > Mounting root from ufs:/dev/ad0s1a but still mounts the ufs ! How do if force it to boot root fs on nfs ? I have tried to do a boot -a then when I prompts me for root fs I enter the proper nfs mount and for RELEASE it would boot diskless but for STABLE is fails !! I have tried to : ok> set rootdev=nfs:<my nfs server ip : mount > ok> boot -h ok> can't determine root device I have also passed it various kernel flags and env options... (mybe wrong ones ... ? ) how do I have the kernel to load the rootfs = nfs root instead of use the currdev ? What does etherboot do when it loads the kernel ? does it pass it special parameters ?? If you are wondering why I just don't boot from etherboot ....etc...(I do ) but... I want to be able to boot my remote systems without a floppie and chose how to boot from loader (via serail console ...I don't have serial access for the bios but I can get serial console with FreeBSD !! ). Either default (use local drive) or load the diskless kernel , then boot diskless. This way I almost the same options ..... and maybe automate it... Any help would be great !! thank you kindly.... nathan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
