This hook loads the necessary modules for a network device.
|
|
Detection will take place at runtime. To minimize the modules
|
|
in the image, add the autodetect hook too.
|
|
For pcmcia net devices please use pcmcia hook too.
|

|
Kernel Parameters:
|
|
An interface spec can be either short form, which is just the name of
|
|
an interface (eth0 or whatever), or long form. The long form consists
|
|
of up to seven elements, separated by colons:
|
|
|
|
ip=<client-ip>:<server-ip>:<gw-ip>:<netmask>:<hostname>:<device>:<autoconf>
|
|
nfsaddrs= is an alias to ip= and can be used too.
|
|
|
|
<client-ip> IP address of the client. If empty, the address will
|
|
either be determined by RARP/BOOTP/DHCP. What protocol
|
|
is used de- pends on the <autoconf> parameter. If this
|
|
parameter is not empty, autoconf will be used.
|
|
|
|
<server-ip> IP address of the NFS server. If RARP is used to
|
|
determine the client address and this parameter is NOT
|
|
empty only replies from the specified server are
|
|
accepted. To use different RARP and NFS server,
|
|
specify your RARP server here (or leave it blank), and
|
|
specify your NFS server in the 'nfsroot' parameter
|
|
(see above). If this entry is blank the address of the
|
|
server is used which answered the RARP/BOOTP/DHCP
|
|
request.
|
|
|
|
<gw-ip> IP address of a gateway if the server is on a different
|
|
subnet. If this entry is empty no gateway is used and the
|
|
server is assumed to be on the local network, unless a
|
|
value has been received by BOOTP/DHCP.
|
|
|
|
<netmask> Netmask for local network interface. If this is empty,
|
|
the netmask is derived from the client IP address assuming
|
|
classful addressing, unless overridden in BOOTP/DHCP reply.
|
|
|
|
<hostname> Name of the client. If empty, the client IP address is
|
|
used in ASCII notation, or the value received by
|
|
BOOTP/DHCP.
|
|
|
|
<device> Name of network device to use. If this is empty, all
|
|
devices are used for RARP/BOOTP/DHCP requests, and the
|
|
first one we receive a reply on is configured. If you
|
|
have only one device, you can safely leave this blank.
|
|
|
|
<autoconf> Method to use for autoconfiguration. If this is either
|
|
'rarp', 'bootp', or 'dhcp' the specified protocol is
|
|
used. If the value is 'both', 'all' or empty, all
|
|
protocols are used. 'off', 'static' or 'none' means
|
|
no autoconfiguration.
|
|
Examples:
|
|
ip=127.0.0.1:::::lo:none --> Enable the loopback interface.
|
|
ip=192.168.1.1:::::eth2:none --> Enable static eth2 interface.
|
|
ip=:::::eth0:dhcp --> Enable dhcp protcol for eth0 configuration.
|
|
|
|
nfsroot=[<server-ip>:]<root-dir>[,<nfs-options>]
|
|
|
|
If the 'nfsroot' parameter is NOT given on the command line, the default
|
|
"/tftpboot/%s" will be used.
|
|
|
|
<server-ip> Specifies the IP address of the NFS server. If this field
|
|
is not given, the default address as determined by the
|
|
'ip' variable (see below) is used. One use of this
|
|
parameter is for example to allow using different servers
|
|
for RARP and NFS. Usually you can leave this blank.
|
|
|
|
<root-dir> Name of the directory on the server to mount as root. If
|
|
there is a "%s" token in the string, the token will be
|
|
replaced by the ASCII-representation of the client's IP
|
|
address.
|
|
|
|
<nfs-options> Standard NFS options. All options are separated by commas.
|
|
If the options field is not given, the following defaults
|
|
will be used:
|
|
port = as given by server portmap daemon
|
|
rsize = 1024
|
|
wsize = 1024
|
|
timeo = 7
|
|
retrans = 3
|
|
acregmin = 3
|
|
acregmax = 60
|
|
acdirmin = 30
|
|
acdirmax = 60
|
|
flags = hard, nointr, noposix, cto, ac
|
|
|
|
root=/dev/nfs
|
|
|
|
If you don't use nfsroot= parameter you need to set root=/dev/nfs
|
|
to boot from a nfs root by autoconfiguration.
