2.1 Introduction
Sections 2.2 – 2.6 contain several standalone tables. Table 11 describes the system memory map, Table 12 shows the I/O map, Table 13 lists the DMA channels, Table 14 defines the PCI 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.
