well, i'm not positive about the MAC thing, but I am quite sure that on
IBM xSeries systems you assigned a different IP address to the BMC,
this was done in the BIOS. And, when I think about that, if it did have
a seperate IP address then it musta had a seperate MAC too...

Course, that was IBM hardware. I'll have to check up on this more
at work tomorrow.

So Julian, are you saying that you have seen this kind of functionality
work on FreeBSD??

Cheers,

Jack
