IBM RS/6000 manual Ab-Cd-Ef-Gh

AB-CD-EF-GH

Device/FRU/Port ID

Connector ID

devfunc Number, Adapter Number or Physical Location Bus Type or PCI Parent Bus

ŸThe AB value identifies a bus type or PCI parent bus as assi firmware.

ŸThe CD value identifies adapter number, adapter's devfunc number,

location. The		devfunc number	is defined as the PCI device numbe
the	function	number.
Ÿ The	EF value	identifies a	connector.

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

Adapters and cards are identified with just AB-CD.

The possible values for AB are:

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
	range	of	0-9, A-H,	J-N,	P-Z (O, I, and lower				case are	omitted) and are e
	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 number times 8, plus the function number). The C and D are characte of 0-9, and A-F (hex numbers). This allows the location code to unique multiple adapters on individual PCI cards.

For pluggable ISA adapters, CD is equal to the order the ISA car

by SMIT or

For integrated ISA adapters, CD

is equal to a unique
