AB-CD-EF-GH

devfunc Number, Adapter Number or Physical Location

Bus Type or PCI Parent Bus

The AB value identifies a bus type or PCI parent bus as assigned by the
firmware.

The CD value identifies adapter number, adapter's devfunc number, or physical
location. The devfunc number is defined as the PCI device number times 8, plus
the function number.

The EF value identifies a connector.

The GH value identifies a port, address, device, or FRU.

Adapters and cards are identified with AB-CD.

The possible values for AB are:

Processor bus

ISA bus

EISA bus

MCA bus

PCI bus used in the case where the PCI bus cannot be identified

PCMCIA buses

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 lowercase are
omitted) and are equal to the parent bus's ibm, aix-loc Open Firmware
Property.

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). Location codes therefore 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.
