[ipxe-devel] iPXE without DHCP 66/67 Settings

During the make process I receive the following message:

cc1: warnings brunt treated as errors
drivers/infiniband/hermon.c: In function 'hermon_probe':
drivers/infiniband/hermon.c:2609:14: error: array subscript is above array bounds
make: *** [bin/hermon.o] Error 1

I am running on openSuse 64bit on VMWare Player.  I am very much a Windows person and making the transition away to either ChromeOS or Suse.

Thanks for the assist.

I would suggest using an embedded script.  You can do this using

  make bin/ipxe.iso EMBEDDED_IMAGE=stjoe.ipxe

where stjoe.ipxe is a text file containing:

  chain tftp://my-server1/my-filename ||
  chain tftp://my-server2/my-filename ||
  chain tftp://my-server3/my-filename ||
  echo Boot failed
  exit 1

This will try each server in turn, falling through to the next entry in the
list if it fails for any reason.  Note the trailing "||", which is required to
prevent the script from immediately aborting if the "chain" command fails.

Note that this method will *not* set the "next-server" and "filename"
variables.  It is possible that your PXE NBP may require these variables to be
set.  If this is the case, you can use a slightly longer version of the above

  set filename my-filename
  set next-server my-server1
  chain ${next-server}/${filename} ||
  set next-server my-server2
  chain ${next-server}/${filename} ||
  set next-server my-server3
  chain ${next-server}/${filename} ||
  echo Boot failed
  exit 1
