Intel® Server Board SE7501WV2 TPS

Configuration and Initialization

4.1.3System Management Mode Handling

The Intel® E7501 MCH supports System Management Mode (SMM) operation in standard (compatible) mode. System Management RAM (SMRAM) provides code and data storage space for the SMI_L handler code, and is made visible to the processor only on entry to SMM, or other conditions, which can be configured using Intel E7501 PCI registers.

4.2I/O Map

The SE7501WV2 allows I/O addresses to be mapped to the processor bus or through designated bridges in a multi-bridge system. Other PCI devices, including the ICH3-S, have built-in features that support PC-compatible I/O devices and functions, which are mapped to specific addresses in I/O space. On the SE7501WV2 server board, the ICH3-S provides the bridge to ISA functions through the LPC bus.

4.3Accessing Configuration Space

All PCI devices contain PCI configuration space, accessed using mechanism #1 defined in the PCI Local Bus Specification.

If dual processors are used, only the processor designated as the Boot-strap Processor (BSP) should perform PCI configuration space accesses. Precautions should be taken to guarantee that only one processor performs system configuration.

When CONFIG_ADDRESS is written to with a 32-bit value (selecting the bus number, device on the bus, and specific configuration register in the device), a subsequent read or write of CONFIG_DATA initiates the data transfer to/from the selected configuration register. Byte enables are valid during accesses to CONFIG_DATA; they determine whether the configuration register is being accessed or not. Only full Dword reads and writes to CONFIG_ADDRESS are recognized as a configuration access by the Intel chipset. All other I/O accesses to CONFIG_ADDRESS are treated as normal I/O transactions.

4.3.1CONFIG_ADDRESS Register

CONFIG_ADDRESS is 32 bits wide and contains the field format shown in the following figure. Bits [23::16] choose a specific bus in the system. Bits [15::11] choose a specific device on the selected bus. Bits [10:8] choose a specific function in a multi-function device. Bit [8::2] select a specific register in the configuration space of the selected device or function on the bus.
