Hi,

I have a number of MVME2300 computers that boot a small ramdisk with
bootp and tftp.  All the MVME2300s are doing basically the same thing so
I would like to avoid having a different kernel for each computer.  I
would like the program that is started in place of init in the ram disk
to set up the network based upon the IP address that was obtained from
bootp.  I do not know how to get at this information though.   Can I
read it from non-vlatile ram?  Can I send out another bootp braodcast
from user-land and get the information again?

Thanks for any leads.

  You should be able to get the ethernet interface's IP address using the
  SIOCSIFADDR ioctl (and friends) on ifr_name "eth0".
