1. The USB signals are all in the RESUME well.
2. Since OC[3:0]# are in the 5 V tolerant resume well, the external biasing resistors are not

PCI Interrupt Requests: In Non-APIC Mode the PIRQx# signals
may be routed to interrupts 3, 4, 5, 6, 7, 9, 10, 11, 12, 14 or 15 as
described in the Interrupt Steering section. Each PIRQx# line has a
separate Route Control Register. These signals are 5 V tolerant.
In APIC mode, these signals are connected to the internal I/O APIC
in the following fashion:
PIRQ[E]
PIRQ[F]
PIRQ[G]
PIRQ[H]
NOTE: When not connected as interrupts on the board, these pins
Interrupt Request 14–15: These interrupt inputs are connected to
the IDE drives. IRQ14 is used by the drives connected to the Primary
controller and IRQ15 is used by the drives connected to the
Secondary controller. These signals are 5 V tolerant.
PCI-X Bus Interrupt Request: The PIRQ# lines from PCI-X
interrupts, INTA, INTB, INTC, INTD], may be routed to these
interrupt lines. PXIRQ[3:0]# are connected to an I/OxAPIC that
resides on the PCI-X bus.
Universal Serial Bus Port 3:0 Differentials: Bus Data/
Address/Command Bus.
NOTE: No external resistors are required on these signals. The
Overcurrent Indicators: These signals set corresponding bits in
the USB controllers to indicate that an overcurrent condition has
occurred.
USB Resistor Bias: Analog connection point for an external
resistor to ground. USBRBIAS should be connected to
USBRBIAS# as close to the resistor as possible.
USB Resistor Bias Complement: Analog connection point for
an external resistor to ground. USBRBIAS# should be connected
to USBRBIAS as close to the resistor as possible.
must be programmed as GPI. This ensures proper interrupt
delivery from internal sources regardless of the board
termination on these pins.
