Fujitsu D2610 User Manual

Brief description of the mainboard
PCI bus interrupts - Selecting correct PCI slot
Extensive information on this section is contained in the "Basic information on mainboard" manual.
To achieve optimum stability, performance and compatibility, avoid the multiple use
of ISA IRQs or PC I 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 update", Page 6 description).
Monofunctional expansion cards
PCI/PCI Express expansion cards require a maximum of one interrupt, which is ca lled the PCI
interrupt INT A. Expansion c ard s that do not require an interrupt can be installed in any desired slot.
Multifunctional expansion cards or expansion cards w ith integrated PCI-PCI b ridge
These expansion cards re quire up to four PCI interrupts: I NT A, INT B, INT C, INT D. How many and
which of these interrupts are used is speci fied in the documen tation provided with the card.
The assignment of the PCI interrupt s to the IRQ Lines is shown in the following table:

First use PCI/PCI Express slots that have a single PCI IRQ Line (no IRQ sharing). If you
must use another PCI/PCI Express slot with IRQ sharing, check whether the expansion card
properly supports IRQ sharing with the other devices on this PCI IRQ Line. The drivers of all
cards a nd components on this PCI IRQ Line m ust also support IRQ sharing.
