Changing the MAC address on X200/T400/T500/W500
-----------------------------------------------
On GM45 laptops with ICH9M southbridge and Intel PHY module, the MAC address
is hardcoded in boot flash, which means it can be changed if you re-flash.
See [ich9utils documentation](../install/ich9utils.md)
If *all* you want to do is change the MAC address, you might try `nvmutil`
instead. See notes below:
Changing the MAC address on ivybridge/sandybridge/haswell (e.g. X230/T440p)

platform with a valid GbE region in flash, where an Intel Flash Descriptor
is used; this includes older GM45+ICH9M machines supported by Libreboot.
The `ich9utils` program is more useful in an lbmk context, because it
generates an entire Intel Flash Descriptor and GbE region from scratch;
coreboot has a similar method in its build system, using its own utility
called bincfg, but this tool is unused in lbmk.
No tool like ich9utils exists for these boards yet, but lbmk includes the IFD
and GbE files in-tree (Intel ME is handled by extracting from Lenovo updates,
which the build system automatically fetches from the internet).
You can use `nvmutil` to change the existing MAC address in a GbE region. This
sets the "hardcoded" MAC address, typically a globally assigned one set by
the vendor, but you can use local addresses, and you can use randomised MACs.
