The BMC did work with me at home. At home I used the bios to configure
the IP.

After changing the IP in the datacenter with bmc-config the BMC did not
work anymore. I did only change the network settings (and later ARP
settings).

Then it's strange I have to edit the Volatile_Access_Mode and
Non_Volatile_Access_Mode. True?

I can buy the motherboard I use with and without a BMC:

CoreIPM says on the website: "coreIPM-LINUX provides a ready to use,
extremely compact drop in solution for platform management. It is
specifically targeted towards shelf and appliance management."

When I see lists like this, I think: "most solutions are far from
perfect, they maybe work with their proprietary software, but give many
problems with standards compliant software."
