DFW-SX910/X710

With the exception of bits 8 to 15 of the 400h offset
address field, the length of the entire ConfigROM field
is made up of 1Fh Quadlets. So ConfigROM from
400h to 47Fh is 128 bytes.

Offset address 420h and key code 8Dh indicate a
NodeUniqueID Leaf offset, but in 1394a-2000, this
field has been eliminated. To ensure compatibility with

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 NodeVendorID/ChipID-Hi +
ChipID-Lo in BusInfoBlock.

The offset address of UnitDirectory is required to be

424h +000004h * 4 = 434h

For offset address 434h, the length of the
UnitDirectory is 3 Quadlets. UnitSpecID (00A02Dh)
conforms to 1394TA standards.
UnitSoftwareVersion (000102h) conforms to the IIDC
standard, v 1.30.

The offset address of UnitDependentInfo is required to
be

440h + 000001h * 4 = 444h
