The system has an On-board Super I/O chipset with 2 serial ports.

The On-board serial ports can be selected as:

Disabled

3F8/IRQ4

2F8/IRQ3

3E8/IRQ4

2E8/IRQ3

Note: Because the ISA Bus Interrupt accepts low to high edge trigger, the

interrupt request line cannot be shared by multiple sources. If an off-

board ISA add-on card with a serial port is installed the user may have

to disable the on-board serial port because it will conflict with IRQ

request line for the off-board serial port.
