Okay, is that something that can be changed via a prom (setenv) command? If not, is that something that could/should be added to OpenBIOS, or would that violate the spirit of getting OpenBIOS as close to OBP?
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.
