2.1 Introduction

Sections 2.2 - 2.6 contain several standalone tables. Table 9 describes the system memory map,
Table 10 shows the I/O map, Table 11 lists the DMA channels, Table 12 defines the PCI
Conventional bus configuration space map, and Table 13 describes the interrupts. The remaining
sections in this chapter are introduced by text found with their respective section headings.
