Interrupt assignment of expansion card slots on the bus board
Note
All system resources (hardware addresses, memory allocation, interrupt allocation, DMA
channels) are dynamically assigned by the firmware or operating system depending on the
hardware setup, drivers, inserted expansion cards and connected external devices.
Assignment is performed automatically and is independent of the resources required by the
connected devices and inserted components. Due to this configuration dependency, clear
statements can only be made by determining them in relation to the system in the final
configuration.
Resources may be viewed as follows under Windows:
1.
Press the "Windows® key" and "R" simultaneously.
2.
Enter "msinfo32" in the "Open" field.
3.
Confirm your entry with "OK".
Applications which place high demands on interrupt performance require a fast interrupt
hardware response time. In order to enable fast hardware response time, the PCI hardware
interrupt may only be allocated to one resource.
Variant 1: 4-slot, 2 x PCI, 2 x PCIe / with piggyback
