Pci Interrupt Request Routing - Premio Computer Athena system System Manual

PCI Interrupt Request Routing

The IRQ, abbreviation of interrupt request line and pronounced I-R-Q,
are hardware lines over which devices can send interrupt signals to the
microprocessor. The "AGP/PCI/Promise" IRQ pins are typically connected to
the PCI bus INT A# ~ INT D# pins as follows:
PCI Slot 1
PCI Slot 2
PCI Slot 3
PCI Slot 4
PCI Slot 5
AGP
Promise ATA 133
The mainboard supports PCI Slot 1~5 Bus Master.
