1. To map the parameters for all PCI cards installed in the server, enter the shell> info io
command at the EFI Shell prompt.
A list of all the installed devices in the server and managed by EFI drivers appears. For

In this example, a single SCSI interface is listed.
For each channel of the SCSI board, note certain information. For example, look at the
information for the SCSI interface. For each channel of this SCSI interface, note the following
information:
• Bus #: Identifies the bus the device is on. This is the same for both channels. In this
example, the bus number is 20.
• Dev #: Identifies the ID the device is assigned on the bus. This is the same for both
channels. In this example, the SCSI 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 SCSI interface has two channels, one channel is 00
and the other is 01.
• Vendor ID: Shows the device vendor ID. This is the same for both channels. For all
SCSI interfaces, the ID is 0x1000.
• Device ID: Shows the device ID. This is the same for both channels. In this example,
the SCSI interface the ID is 0x0030.
• Slot #: Identifies the physical card slot in the system where the SCSI interface is
installed. This is the same for both channels. In this example, the SCSI interface is on
the system board, therefore the slot number is xx.
• Path: Identifies the device path. In this example, the SCSI interface path is
Acpi(HWP0002,200)/Pci(1|0) for channel A and Acpi(HWP0002,200)/Pci(1|1)
for channel B.
Using the SCSI interface information from this example, the combined information that tells
you this is a SCSI interface are the following (shown in bold, for highlighting purposes):
00 20 01 00 0x1000 0x0030 xx Acpi(HWP0002,200)/Pci(1|0)
00 20 01 01 0x1000 0x0030 xx Acpi(HWP0002,200)/Pci(1|1)
The vendor (0x1000) and device (0x0030) are the IDs for a SCSI interface. Of the devices with
those IDs, this device has two channels (Fnc # of 00 immediately followed by Fnc # of 01).
