Adding PCI Express cards

The PCI Express x16 slot is intended for graphics cards, and the PCI Express x1 slot for

PCI Express x1 cards.

Technical data:

32 bit / 33 MHz PCI slots

5 V and 3.3 V supply voltage

3.3 V auxiliary voltage

To achieve optimum stability, performance and compatibility, avoid the multiple use of

IRQ Lines (IRQ sharing). Should IRQ sharing be unavoidable, then all involved devices

and their drivers must support IRQ sharing.

IRQ Lines connect PCI/PCI Express slots and onboard components to the interrupt controller. IRQ

Lines are permanently wired on the mainboard.

Which IRQs are assigned to the IRQ Lines is normally automatically specified by the BIOS (see

description in "BIOS Setup").

Monofunctional expansions 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 installed in any desired slot.
