Intel® Server Board SE7501WV2 TPS

4.Configuration and Initialization

This section describes the configuration and initialization of various baseboard sub-systems as implemented on the SE7501WV2 server board.

4.1.1Main Memory

All installed memory greater than 1 MB is mapped to local main memory, up to the top of physical memory, which is located at 12 GB. Memory between 1 MB to 15 MB is considered standard ISA extended memory. 1 MB of memory starting at 15 MB can be optionally mapped to the PCI bus memory space.

The remainder of this space, up to 12 GB, is always mapped to main memory, unless Extended SMRAM is used, which limits the top of memory to 256 MB.

4.1.1.1PCI Memory Space

Memory addresses below the 4 GB range are mapped to the PCI bus. This region is divided into three sections: High BIOS, APIC Configuration Space, and General-purpose PCI Memory. The General-purpose PCI Memory area is typically used for memory-mapped I/O to PCI devices. The memory address space for each device is set using PCI configuration registers.

4.1.1.2High BIOS

The top 2 MB of Extended Memory is reserved for the system BIOS, extended BIOS for PCI devices, and A20 aliasing by the system BIOS. The Intel® Xeon™ processor begins executing from the high BIOS region after reset.

4.1.1.3I/O APIC Configuration Space

A 64 KB block located 20 MB below 4 GB is reserved for the I/O APIC configuration space.

4.1.1.4Extended Xeon Processor Region (above 4GB)

An Intel® Xeon™ processor-based system can have up to 64 GB of addressable memory. The BIOS uses the Extended Addressing mechanism to use the address ranges.

4.1.2Memory Shadowing

Any block of memory that can be designated as read-only or write-only can be “shadowed” into main memory. This is typically done to allow ROM code to execute more rapidly out of RAM. ROM is designated read-only during the copy process while RAM at the same address is designated write-only. After copying, the RAM is designated read-only and the ROM is designated write-only (shadowed). Processor bus transactions are routed accordingly. Transactions originated from the PCI bus or ISA masters and targeted at the shadowed memory block will not appear on the processor’s bus.
