420h + 000002 * 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 * 4 = 434h
The entry with key D4 in the unit directory (440h in this case) provides the
offset for unit dependent info:
440h + 000001 * 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 * addrOffset)
= 420h + (4 * 000002h)
= 428h
