I don't want it stored there :=)

Some recent motherboards are putting ethernet address in CMOS instead of
the serial EEPROM. Yes, I know this is stupid: I have one board with a MAC
address of 0:0:0:0:0:0, because I slipped and zeroed CMOS once. But the
vendors are doing it.

What they seem to do in some cases is copy the CMOS-based address to FLASH
when you update BIOS. Then each time they come up the copy the FLASH-based
address to CMOS. This allows them to hope that you never accidently zero
CMOS while upgrading FLASH. Yeah right.

But yes, I agree it is dumb, but I can't do anything about it.
