i'm playing with an embedded linux and i can boot using boot time options "noinitrd", "ip=" and "nfsroot=". but other than noinitrd, i don't see where the other two are documented.
Chek the kernel docs. Both are listed in kernel-parameters.txt in either /usr/src/linux-2.4/Documentation/ or /usr/share/doc/kernel-doc-<kversion>.
nfsroot is for NFS root filesystems, diskless clients. ip is related to PNP, but I don't know what it does. -Thomas
