====== Integreting BKO with latest gpxe and rom-o-matic ======

The latest gpxe code, and gpxe version used by rom-o-matic, both are creating trubble while booting.\\
I am hosting them at [[http://etherboot.org/share/pravin/BKO/rom-o-matic/]]
Following is the error thrown.

I am not sure if this problem is from gpxe or from pxelinux. My guess is that, it should be gpxe problem
as same setup is working fine with my version of gpxe code.\\
all my modifications are listed on page [[pxekniferomomatic]]
===== Error Location =====
Problem should be because of latest gpxe code ///pub/share/pravin/gpxe.git//, because when I use the code which I normally use on my machine (which is copied on ///pub/share/pravin/gpxe//), it works fine.

===== trying to see if networking works =====
the location for problematic gpxe is

    [netdevice] Fix incorrect value for MAX_LL_HEADER_LEN
    
    MAX_LL_HEADER_LEN is erroneously set to 6 rather than 14, resulting
    in possible data corruption whenever we send an ARP packet.
    
    Fix value and add a comment explaining why MAX_LL_ADDR_LEN is greater
    than MAX_LL_HEADER_LEN.
