how to specify a static ip at prompt

["pierre-yves.verdon" <pierre-yves.verdon@xxxxxxxxxxxxxxxxxxx>]

well the ks.cfg file is on an nfs server
i don't want to use a dhcp server, is there a way i could specify a
static ip?
is it possible to do an equivalent as:
ks=nfs:1.2.3.4:/export/7.1/ks.cfg ksdevice=eth1  ksip=1.2.3.5
