Intel® Server Board SE7210TP1-E TPS
Functional Architecture
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.
3.4.1.4
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.
3.4.1.5
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.
3.4.1.6
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-0DFFFFh and will follow all rules with respect to the
option ROM space. The SE7210TP1-E BIOS will integrate option ROMs for the Intel 82547GI,
Intel 82551QM, ATI Rage XL, SATA RAID and Adaptec 7901 SCSI controller.
3.4.1.7
Zero Channel RAID (ZCR) Capable Slot
The SCSI version of the Server Board SE7210TP1-E is capable of supporting the following zero
channel RAID controllers, the Intel® RAID Controller SRCZCR and the Adaptec* ASR-2010S
RAID adapter. ZCR cards are only supported in slot one the P64-A PCI segment.
The ZCR add-in cards leverage the on-board SCSI controller along with their own built-in
intelligence to provide a complete RAID controller subsystem on-board. The riser card and
baseboard use an implementation commonly referred to as RAID I/O Steering (RAIDIOS)
specification version 0.92 to support this feature. If either of these supported RAID cards are
installed, then the SCSI interrupts are routed to the RAID adapter instead of to the PCI interrupt
controller. Also the IDSEL of the SCSI controller is not driven to the controller and thus will not
respond as an on-board device. The host-based I/O device is effectively hidden from the system.
