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

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
followed by Fnc # of
01
). Also, this
SCSI interface has a non-numeric (XX) slot # indicating that it is on the system board.

From the EFI Shell prompt, enter the following command to obtain the controller’s handle
for the SCSI interface:
