Adding PCI Express cards
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.
Adding PCI cards
Technical data:
32 bit / 33 MHz PCI slots
5 V and 3.3 V supply voltage
3.3 V auxiliary voltage
PCI bus interrupts - Selecting correct PCI slot
To achieve optimum stability, performance and compatibility, avoid the multiple use of i 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.
