PCI / PCIe cards and the on-board PCI / PCIe devices require PCI interrupt channels. These
interrupt channels can be shared and are plug-and-play compatible, that is, several devices
can share the same interrupt. The IRQ is assigned automatically.
PCI interrupt channels must be derived from the PIC interrupt pool, that is PCI modules also
use PIC resources. These IRQ channels are assigned automatically.
The Host PCI IRQ channels A to H are permanently assigned in APIC mode. These default
settings cannot be modified.
The Host PCI IRQ channels A to H in PIC mode are assigned automatically in BIOS. The
assignment can be changed by disabling functions. Resulting free IRQs are assigned to the
slots.
Memory address assignments
PCI VGA modules can be operated with expansion ROM up to 48K.
