Each row represents one slot or onboard device, each column represents one PCI Interrupt Line. All
devices on one column share this line. For standard PCI cards or devices (e.g. those that use only
one interrupt) an "A" in a column means that it uses this PCI Interrupt Line. If other cards or devices
also use this line, this means the line is shared. According to the PCI specific ation all cards and
devices must support interrupt sharing. Some cards, however, might cause instabilities or
performance degradation if they share an interrupt. Try moving those cards to a slot where they
won’t share an interrupt.
Some cards may use more than one interrupt. For these cards also take into consideration the s mall
"B" "C" "D" entries in the table.

YOU MUST ALWAYS unplug all three power connectors from the motherboard before
performing system hardware changes. Otherwise you may damage the board and/or
expansion device.
Connecting External Devices Connecting external devices to the motherboard is an easy task. The standard devices you should
expect to plug into the motherboard are keyboards, mice, and printer cables. The following diagram
will detail the ATX port stack for the mainboard D1692:
