to storage located on the IOU, as well as platform CD-RW/DVD-RW drive or tape
drive resources at the locations shown in
TABLE A-9. In the PCIe device path, x is LSB-
dependent, and is assigned a value as shown in
TABLE A-2. xx is the XSB number and
is in the range from 00-15. nn is the number associated with the PSB to which the CD-
RW/DVD-RW drive or tape drive is attached, as further explained in the table
footnote.
