2.1 Introduction
Sections 2.2 - 2.6 contain several standalone tables. Table 11 describes the system memory map, Table 12 lists the DMA channels, Table 13 shows the I/O map, Table 14 defines the PCI Conventional bus configuration space map, and Table 15 describes the interrupts. The remaining sections in this chapter are introduced by text found with their respective section headings.
2.2 Memory Resources
2.2.1Addressable Memory
The board utilizes 4 GB of addressable system memory. Typically the address space that is allocated for PCI Conventional bus
•BIOS/firmware hub (2 MB)
•Local APIC (19 MB)
•Digital Media Interface (40 MB)
•Front side bus interrupts (17 MB)
•PCI Express configuration space (256 MB)
•MCH base address registers, internal graphics ranges, PCI Express ports (up to 512 MB)
