When the number of PCI devices exceeds 10, any additional devices will appear
as embedded devices, even if they require an IRQ assigned to them. The
embedded devices are listed in the order in which they were detected. To
associate embedded devices with particular PCI expansion boards, you must
know the number of devices (excluding PCI-to-PCI bridges, which are not listed
in the SCU) on each PCI expansion board. If there are many embedded
devices, start matching the PCI expansion boards in the highest slot number
with the embedded devices at the bottom of the list (above the embedded VGA
device). As an example, assume that a server has two controllers installed, one
in PCI slot 1 and the other in PCI slot 2. The SCU might show the following:
•
PCI 1 PCI Memory Controller IRQ14
•
PCI 2 PCI SCSI Controller IRQ10
•
PCI SCSI Controller
•
PCI SCSI Controller
•
PCI SCSI Controller (7880)
•
PCI Ethernet Controller
•
PCI VGA
In this case, the first two references are devices on the controller in PCI slot 1,
the next two are associated with the controller in PCI slot 2, and the final
reference is for the onboard controller.
