Re: ARP interfering with Etherboot TFTP?

Some further information.  I tried the same server with a different
client using an Intel Pro/1000 rather than Broadcom NIC.  Both with
the same undi.zpxe.  The Intel client ran to completion, downloading
the whole kernel file (last block 27675).  Below is the trace
information around the only ARP exchanges during the download of the
kernel file.

I will try to check if there is a more recent version of the BIOS
firmware for the Broadcom NIC.
