Installing Add-In Cards
Before installing add-in cards, you should ensure that they are fully compatible with your
motherboard. If in doubt, check the specifications with the manufacturer.
Simply find the appropriate slot for your add-in card and insert the card firmly.
Never force any add-in cards into any slots if they do not seat in place. Doing so will damage the
motherboard and void your warranty.
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 specification 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 small
“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 D1818:
1 PS/2 Keyboard and PS/2 Mouse Connector
To install a PS/2 port keyboard and mouse, plug the mouse to the upper port (green) and the
keyboard to the lower port (purple).
2 / 3 Parallel Port / Serial Port
This connector supports 1 standard COM port and 1 Parallel port. Device like printer can be
connected to Parallel port ; mouse and modem etc can be connected to Serial port.
