420h + 000002h x 4 = 428h

The entry with key D1 in the root directory (424h in this case) provides the
offset for the unit directory as follows:

424h + 000004 x 4 = 434h

The entry with key D4 in the unit directory (440h in this case) provides the
offset for unit dependent info:

440h + 0000xx * 4 = 444h

To compute the effective start address of the node unique ID leaf

currAddr

= node unique ID leaf address

destAddr

= address of directory entry

addrOffset

= value of directory entry

destAddr

= currAddr + (4 x addrOffset)

= 420h + (4 x 000002h)

= 428h
