Sections 2.2 - 2.6 contain several standalone tables. Table 10 describes the system memory map,
Table 11 lists the DMA channels, Table 12 shows the I/O map, Table 13 defines the PCI
Conventional bus configuration space map, and Table 14 describes the interrupts. The remaining
sections in this chapter are introduced by text found with their respective section headings.
The board utilizes 4 GB of addressable system memory. Typically the address space that is
allocated for PCI Conventional bus add-in cards, PCI Express configuration space, BIOS (SPI
Flash), and chipset overhead resides above the top of DRAM (total system memory). On a system
that has 4 GB of system memory installed, it is not possible to use all of the installed memory due
to system address space being allocated for other system critical functions. These functions include
the following:
