Intel® Server Boards SE7320SP2 and SE7525GP2

Functional Architecture

Revision 4.0

31

SIO Chip: National Semiconductor* PC87417 Super I/O

Hardware monitoring sub-system: SMBUS

Intel

®

82541 PCI gigabit NIC

Two expansion slots

3.6.1.2

P64-A: 64-bit, 66 MHz PCI Subsystem

One 64-bit PCI-X bus segment is directed through the Intel

®

6300ESB I/O hub. The PCI-X

segment, P64-A, supports the interface for two 3.3-V, 64-bit PCI-X slots.

3.6.1.3

P64-Express4: x4 PCI Express* Bus Segment

The P64-Express4 bus segment supports x4 PCI Express* signaling. These server boards
implement a x8 PCI Express connector on this bus to enhance the breadth of supported
devices, however all devices will operate at a maximum speed of x4 (2 GB/s).

3.6.1.4

P64-Express16: x16 PCI Express bus segment

Intel

®

Server Board SE7525GP2 only: The P64-Express16 bus segment supports x16 PCI

Express signaling.

3.6.1.5 Scan

Order

The BIOS assigns PCI bus numbers in a depth-first hierarchy, in accordance with the PCI Local
Bus Specification. When a bridge device is located, the bus number is incremented in exception
of a bridge device in the chipsets. Scanning continues on the secondary side of the bridge until
all subordinate buses are defined. PCI bus numbers may change when PCI-PCI bridges are
added or removed. If a bridge is inserted in a PCI bus, all subsequent PCI bus numbers below
the current bus will be increased by one.

3.6.1.6 Resource

Assignment

The resource manager assigns the PIC-mode interrupt for the devices that will be accessed by
the legacy code. The BIOS will ensure the PCI BAR registers and the command register for all
devices are correctly set up to match the behavior of the legacy BIOS. Code cannot make
assumptions about the scan order of devices or the order in which resources will be allocated to
them. The BIOS will support the INT 1Ah PCI BIOS interface calls.

3.6.1.7

Automatic IRQ Assignment

The BIOS automatically assigns IRQs to devices in the system for legacy compatibility. No
method is provided to manually configure the IRQs for devices.

3.6.1.8

Option ROM Support

The option ROM support code in the BIOS will dispatch the option ROMs in available memory
space in the address range 0c0000h-0e7fffh and will follow all rules with respect to the option
ROM space. The BIOS integrates option ROMs for all the integrated components on the board.
