PCI Bus Configuration Space
The table below lists the configuration space used for the primary PCI bus. The PCI bus uses type 1
configuration access, which specifies two 32-bit I/O ports used as the index register (0CF8h) and the
data register (0CFCh).
Device Device Number 0CF8h Value
Host-to-PCI Bridge (PCMC) 0 800000XX
PCI-to-ISA Bridge 2 800010XX
Graphics Accelerator 5 800028XX
Ethernet Controller 6 800030XX
SCSI Controller 7 800038XX
PCI Slot 1 D 800068XX
PCI Slot 2 E 800070XX
PCI Slot 3 F 800078XX
Each PCI slot on the riser card has four available interrupt lines: INTA, INTB, INTC, and INTD.
These are connected to the PCI interrupts PIRQ0 through PIRQ3, as shown below:
Interrupt Line Slot 1 Slot 2 Slot 3 Slot 4 Slot 5 Slot 6
INTA PIRQ0 PIRQ1 PIRQ2 PIRQ3 PIRQ0 PIRQ1
INTB PIRQ1 PIRQ2 PIRQ3 PIRQ0 PIRQ1 PIRQ2
INTC PIRQ2 PIRQ3 PIRQ0 PIRQ1 PIRQ2 PIRQ3
INTD PIRQ3 PIRQ0 PIRQ1 PIRQ2 PIRQ3 PIRQ0
ISA Bus IRQ Assignments
The ISA slots on the riser card accommodate ISA based option boards and a 16-bit wide expansion
bus. The ISA bus interrupt (IRQ) assignments are defined below.
