With the exception of bits 8 to 15 of the 400h offset address field, the length of the entire ConfigROM is made up of 1Fh Quadlets. So the ConfigROM from 400h to 47Fh is 128 bytes.
Offset address 420h and key code 8Dh indicate a NodeUniqueID Leaf offset, but in
previous models, this field has been retained in this model, but in writing drivers and software applications, be sure to ignore this field. For a NodeUniqueID, use
The UnitDirectory offset address is required to be 424h +000004h * 4 = 434h
