Hi Florian,

This is the result you asked for:

# lspci -nn | grep BCM5708
0f:00.0 Ethernet controller [Class 0200]: Broadcom Corporation NetXtreme 
II BCM5708S Gigabit Ethernet [14e4:16ac] (rev 12)

Also, this the output from the HP firmware upgrade tool listing firmware 
versions:

# ./CP008244.scexe -c eth3
MAC          PCI-ID              NIC
001A4B502016 14E4-16AC-103C-703D HP NC373F PCIe Multifunction Gig Server 
Adapter

      (Installed)                (Available)              Interface
      Image      Version         Image      Version       eth3
----------------------------------------------------------------------
       BC        1.9.6           BC         1.9.6
       iSCSI     1.1.8           iSCSI      1.1.8
                                 PXE        2.8.5

Now I look at this I can see my upgrade has disabled PXE.  I don't know 
if this is significant....?

Thanks again for all your help.

Ben
