Notes
1. Internally generated by the PIB.
2. After a reset, all ISA IRQ interrupt lines default to edge-sensitive
mode.
3. These PCI interrupts are routed to the ISA interrupts by
programming the PRIQ Route Control registers in the PIB. The
PCI-to-ISA interrupt assignments in this table are suggested. Each
ISA IRQ to which a PCI interrupt is routed must be programmed for
level-sensitive mode. Use this routing for PCI interrupts only when
the RavenMPIC is either not present or not used.

4. The RavenMPIC, when present, should be used for these interrupts.
ISA DMA Channels
The MVME2300 series boards do not implement any ISA DMA channels.
