  Hi Surekha,

  You can use a set of tools from "busybox" that 
  includes a small statically linked "shell" and
  dhcp client utility program(s) and create a initrd 
  (ramdisk) that download via pxelinux.

   The linuxrc script would then bring up the 
   network something like :

   insmod <your nic>
   ifconfig up eth0 my_ip_addr
   dhcpl  >  target_info   # query the server 
   insmod iscsi_mod 
   iscsi_conf   cat `target_info`  # user utility to start iscsi

  Ping me offline and I can share the 
  diskless boot sequence I did with unh-iscsi
  ramdisk if your interested.
