Using System Resources
This chapter provides information on using system resources, such as interrupt requests
(IRQs) and basic input/output system (BIOS) parameter settings, to configure the system to
use additional option boards. 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.
