Slots; Pci Slots; Pci Interrupt Request Routing - MSI K1-1000D User Manual

The motherboard provides two 64-bit PCI-X 100/133MHz slots. One is full
length and the other is half length.

PCI Slots

Two PCI slots allow you to insert the expansion cards to meet your needs.
When adding or removing expansion cards, make sure that you unplug the power
supply first. Meanwhile, read the documentation for the expansion card to make any
necessary hardware or software settings for the expansion card, such as jumpers,
switches or BIOS configuration.

PCI Interrupt Request Routing

The IRQ, acronym of interrupt request line and pronounced I-R-Q, are hard-
ware lines over which devices can send interrupt signals to the microprocessor.
The PCI IRQ pins are typically connected to the PCI bus INT A# ~ INT D# pins as
follows:
Devices
PCI Slot 1
PCI Slot 2
LAN
VGA
SCSI
Primary IDE Interrupt: IRQ14 (for AMD8111)
Secondary IDE Interrupt: IRQ15 (for AMD8111)
