Fujitsu D2608 User Manual

Brief descript ion of mainboard
PCI bus interrupts - Selecting correct PCI slot
Extensive inform ation on this section is contained in the manual "Basic information on mainboard".
To achieve optimum stability, p erformance and compatibility, avoid the multiple use
of ISA IRQs or PCI IRQ Lines (IRQ sharing). Should IRQ sharing be unavoidable,
then all involved devices and their drivers must support IRQ sharing.
Which ISA IRQs are assigned to the PCI IRQ Lines is normally automatically
specified by the BIOS ( see "BIOS Setup" description).
Monofu nct ional expansion cards
PCI/PCI Express expansion cards require a maximum of one interrupt, which is called the PCI
interrupt INT A. Expansion cards that do not require an interrupt can be inst alled in any desired slot.
Multifunctio nal expansion cards or expansion cards with integrated PCI-PCI bridge
These expansion cards require up to four PCI interrupts: INT A, INT B, INT C, INT D. H ow many
and which of the se interrupts are used is specified in the documentation provided with the card.
The assignment of the PCI interrupts to the IRQ Lines is show n in the following tab le:
