1. At the EFI Shell prompt, enter the info io command to map the parameters for all PCI cards
installed in the server.
A list of all the devices that are installed in the server blade and managed by EFI drivers
displays. The output looks like this:

In the example above, a single interface is shown in the listing. The information for both
channels of the interface is shown in bold, for highlighting purposes.
For each channel of the board, you need to note certain information. As an example, look at
the information for the interface (the first two bold lines). For each channel of this interface,
note the following information:
Bus #–identifies the bus the device is on; for the interface, this is the same for both
channels. In this example, the bus number is 20.
Dev #—the ID the device is assigned on the bus; for the interface, this is the same for
both channels. In this example, the interface is device 01.
Fnc #–identifies the channel of the device (00 for channel A, 01 for channel B, and
so on). In this example, because the interface has two channels, one channel is 00 and
the other is 01.
Vendor ID–shows the device's vendor ID; for the interface, this is the same for both
channels. For all the interface the ID is 0x1000.
Device ID–shows the device ID; for the interface, this is the same for both channels.
For the interface the ID is 0x0030.
Slot #–identifies the physical card slot in the server where the interface is installed; for
the interface, this is the same for both channels. In this example, the interface is on the
system board therefore the slot number is xx.
Path—identifies the device's path; for the interface, this is the same for both channels.
In this example, the interface path is Acpi(HWP0002,200)/Pci(1|0) for channel A
and Acpi(HWP0002,200)/Pci(1|1) for channel B.
Using the interface information from the example above, the pieces of information that,
combined, tell you this is an interface are the following (shown in bold, for highlighting
purposes):
00 20 01
00 20 01
The vendor (0x1000) and device (0x0030) are the IDs for a interface. Of the devices with
those IDs, this device has two channels (Fnc # of 00 immediately followed by Fnc # of 01).
Also, this interface has a non-numeric (XX) slot # indicating that it is on the system board.
2. From the EFI Shell prompt, enter thedevtree command to obtain the controller's handle for
the interface.
A tree of all EFI-capable devices installed in the server displays. The output looks like this:
