Ÿ The EF value identifies a connector.
ŸThe GH value identifies a port, address, device, or FRU.
Adapters and cards are identified with just
The possible values for AB are:

The possible values for CD depend on the adapter/card.
For pluggable | PCI | adapters/cards, | CD is the device's devfunc number (PCI device | ||
number | times | 8, plus | the function | number). The C and D are characters in the rang | |
of | allows the location code to uniquely identify | ||||
multiple | adapters | on | individual PCI | cards. |
For pluggable ISA adapters, CD is equal to the order the ISA cards defined/configured either by SMIT or the ISA Adapter Configuration Service Aid.
For integrated ISA adapters, CD | is equal to a unique | code identifying the ISA | |||||
adapter. In most cases this is | equal | to the adapter's physical location code. | |||||
where | a | physical | location code | is not | available, CD will be FF. | ||
EF | is | the | connector | ID. It is | used to | identify the | adapter's connector that a |
is | attached to. |

GH is used to identify a port, device, or FRU. For example:
Ÿ For async devices GH defines the port on the fanout box. The values are 00 15.
Ÿ For a diskette drive H defines which diskette drive 1 or 2. G is always
Ÿ For all other devices GH is equal to 00.
For | integrated | adapter, | same as the definition for a | pluggable ada |
For | example, the location code for a | diskette drive is | second | |
diskette drive | is |

For SCSI the location code is defined as:
