  • Page 41: Resources

    Resources This chapter lists and describes system board resources. ISA Interrupt Requests (IRQs) Most Industry Standard Architecture (ISA) peripheral devices installed in the system require you to reserve an interrupt request (IRQ). Peripheral Component Interconnect (PCI) peripheral devices share system resources and can use the same IRQ. (See “PCI-to-ISA Interrupt Map” in this chapter.) At least one IRQ must be unassigned for use with your system’s PCI devices.
