Features PCI(e) slots
PCI slots
The following table shows an overview of the PCI slots:
Slot 3 and slot 6 are automatically used as x8 slots, if slot 2 respectivly slot 5
are not occupied.
PCI, PCI-X, PCI Express interrupts
Each device connected to a PCI bus or PCI Express can use up to four interrupt
signals depending on the functionality.
PCI and PCI-X buses use four lines named INTA to INTD, typically connected
to all devices on the bus in order to periodically balance interrupt load. An
interrupt signal may thereby be used simultaneously by multiple devices
(interrupt sharing).
PCI Express devices send their interrupts through messages. The interrupts are
defined by the system design.
