The EF value identifies a connector.
The GH value identifies a port, address, device, or FRU.
Adapters and cards are identified with just AB-CD.
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 range
of 0-9, and A-F (hex numbers). This 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. In cases
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 resource
is attached to.
GH is used to identify a port, device, or FRU. For example:
For async devices GH defines the port on the fanout box. The values are 00 to
15.
For a diskette drive H defines which diskette drive 1 or 2. G is always 0.
For all other devices GH is equal to 00.
For integrated adapter, EF-GH is the same as the definition for a pluggable adapter.
For example, the location code for a diskette drive is 01-D1-00-00. A second
diskette drive is 01-D1-00-01.
For SCSI the location code is defined as:
00 Processor bus
01 ISA bus
02 EISA bus
03 MCA bus
04 PCI bus used in the case where the PCI bus cannot be identified
05 PCMCIA buses
xy For PCI adapters where x is equal to or greater than 1. The x and y are characters in the
range of 0-9, A-H, J-N, P-Z (O, I, and lower case are omitted) and are equal to the parent
bus's ibm, aix-loc Open Firmware Property.
