8 Using System Resources
This chapter provides information on using system resources, such as interrupt requests
(IRQs), direct memory access (DMA) channels, input/output (I/O) addresses, and memory
addresses. The chapter covers specific Peripheral Component Interconnect (PCI) and
Industry Standard Architecture (ISA) devices offered by Intergraph as system options.
Intergraph Computer Systems has determined that the devices discussed in this chapter
require specific resource settings to ensure proper system operation.
See Chapter 4, “Configuring the BIOS,” for information on running the BIOS Setup
program and changing BIOS parameter settings.
See the System Reference for additional information on system resources.
