Enter OpenBoot Prom
Method 1: simple result
ok .enet-addr
0:3:ba:xx:xx:xx

ok .idprom
Format/Type: ... Ethernet: 0 3 ba xx xx xx Date: ... Serial: ... Checksum: ...
Method 3: in-depth result
ok show-devs
Look through results for 'ethernet', 'network' or similar words. There will probably be multiple network devices.
ok cd /pci@1f,0/ethernet@5
ok .properties
You will receive an output of device properties, look for:
local-mac-address 00 03 ba xx xx xx
Repeat as necessary.
