Multi I/O Port Addresses

Default settings for multi-I/O port addresses are shown in the table
below.
Port
LPT1* 378H
COM1 3F8H
COM2 2F8H
* If default I/O port addresses conflict with other I/O cards (e.g.
sound cards or I/O cards), you must adjust one of the I/O addresses
to avoid address conflict. (You can adjust these I/O addresses from
the BIOS.
Note: Some sound cards have a default IRQ setting for IRQ7, which
may conflict with printing functions. If this occurs do not use
sound card functions at the same time you print.

Connectors

Attach the mainboard to case devices, or an external battery, via
connectors on the mainboard. Refer to Figure 1-1 for connector
locations and connector pin positions.
1. PW – AT Power Supply Connectors
The mainboard requires a power supply with at least 200 watts
and a Òpower goodÓ signal. PW has two six-pin male header
connectors. Plug the dual connectors from the power directly
onto the board connector while making sure the black leads are in
the center.
