Yes it was the IP_PNP and NFS_ROOT options that were necessary. however
now i am faced with another problem which didn't quite notice before.

the kernel complains

IP-Config : No network devices available. 

Looking up port of RPC 100003/2 on 192.168.0.100
portmap : RPC call returned error 101
Root-NFS: Unable to get nfsd port number from server, using default. 

repeat of above error.

Root-NFS: Server returned -101 while mounting /usr/lib/fai/nfsroot

VFS: Unable to mount root fs via NFS trying floppy
..

i am not quite sure if the error means that the network card is not
configured or the there is a problem with nfs server itself. 

the network card i have is 

0000:06:07.0 Ethernet controller: Intel Corp. 82541GI/PI Gigabit
Ethernet Controller (rev 05)

i am using e1000 driver.

thank you,

regards
john.
