2.7 Serial Ports (COM1 : CN9; COM2 : CN10/CN38 )
The AIMB-740/741 offers two serial ports, CN9 as COM1 and CN10 (for
AIMB-740/741)/CN38 (for AIMB-741) as COM2. These ports can con-
nect to serial devices, such as a mouse or a printer, or to a communica-
tions network.
The IRQ and address ranges for both ports are fixed. However, if you
want to disable the port or change these parameters later, you can do this
in the system BIOS setup.
Different devices implement the RS-232 standard in different ways. If
you are having problems with a serial device, be sure to check the pin
assignments for the connector.
2.8 PS/2 Keyboard and Mouse Conn (CN11)
Two 6-pin mini-DIN connectors (CN11) on the motherboard provide con-
nection to a PS/2 keyboard and a PS/2 mouse, respectively.
