The HostID and MAC address are part of the idprom on Sun Machines. 
That's a 32-byte static rom area on pre-sun4v machines, you can see it 
as a property with "prtconf -pv" from Solaris, or with .properties from 
"/" at the ok prompt.

It's not supposed to be changeable by the customer, it's supposed to be 
fixed at the factory so the serial number is meaningful.
