Brief description of mainbo ard
Multifunctio nal expansi on cards or expa nsio n cards with integrated PCI-PCI bridge
These expansion cards require up to four PCI interrupts: INT A, INT B, INT C, INT D. How many
and which of the se interrupts are used is speci fied in th e documentation provided with the card.
The assignment of the PCI interrupts to the IRQ Lines is show n in the following table:

Use first PCI/PCI Express slo
ts that have a single PC I IRQ Line (no IRQ sharing). If you
must use another PCI/PCI Exp
ress slot with IRQ sharing, check whether the expansion card
properly supports IRQ shari
ng with the other devices on this PCI IRQ Line. The drive rs of all
cards and components on thi
s PCI IRQ Line must also support IRQ sharing.
