As I have not used such a beast myself yet, I can give you only the
following tips (courtesy of Christian Leutloff <leutloff@sundancer.tng.oche.de>):
- You can't use ``normal'' bootroms.
- There is a
netboot packet by Gero Kuhlmann, that provides
for bootroms for Linux, and further information. netboot is
available from the local Linux mirror, or as a Debian package
(netboot-0.4).
- Read the documentation coming with your boot rom carefully.
- You probably will have to enable the tftpd on the server, but
this depends upon your boot rom's way of loading the kernel.
- Any informations on bootrom vendors of these Linux variety,
mentioned above, as not everybody has access to prom burner :(
(especially in europe, as I'm located there.) welcome, I'll include
them then here.
If you have exported the root filesystem with the correct name for the
default naming and your NFS server is also the RARP server
(which implies that the boxes are on the same subnet.), than you can
just boot the kernel by cating it to a disc. (You have to set the
root device in the kernel to 0:255.) This assumes, that the root
directory on the server is /tftpboot/IP-Address
(this value can be changed when compiling the kernel.)
Give the kernel all needed parameters when booting, and add
nfsroot=<server-ip-addr>:</path/to/mount>
where server-ip-addr is the IP-address of your NFS-server, and
/path/to/mount is the path to the root directory.
Tips:
- When using LILO consider using the ``
lock'' feature: Simply
type in once all the correct parameters and add
``lock''. Next time when booting let LILO timeout.
- When generating a workstation specific boot disk, you can
also use the
append= feature in lilo.conf.
In addition to nfsroot give a
nfsaddrs=<wst-IP>:<srv-IP>:<gw-IP>:<netm-IP>:<hostname>
commandline argument for the kernel. The kernel will setup eth0
with the given parameters:
- wst-IP
machine's IP-Address
- srv-IP
NFS-server IP-Address
- gw-IP
gateway
- netm-IP
netmask
- hostname
machine name
