17 AIMB-784 User Manual
Chapter 2 Connecting Peripherals
The AIMB-784 includes both VGA and DVI-D interface that can drive conventional
CRT and LCD displays. Pin assignments of VGA1 and DVI1/DVI2 are detailed in
Appendix B.
2.6 Serial Ports (COM1, COM2, COM3, COM4, COM5
& COM6)
The AIMB-784 offers six serial ports (one on the rear panel and five onboard). RS-
232/422/485 mode is selected by BIOS for COM3. These ports can connect to a
serial mouse, printer or communications network. The IRQ and address ranges for
those 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 imple-
ment the RS-232/422/485 standards in different ways. If you are having problems
with a serial device, please be sure to check the pin assignments for the connector.
2.7 PS/2 Keyboard and Mouse Connector (KBMS1)
Two 6-pin mini-DIN connectors (KBMS1) on the rear panel of the motherboard pro-
vide PS/2 keyboard and mouse connections.
