4.1.2.3.1 Serial Port1/2 Address
This option specifies the base I/O port address and Interrupt Request address of serial port
1/2. The Optimal setting is 3F8/IRQ4. The Fail-Safe default setting is Disabled.
Item Description
Disabled
Set this value to prevent the serial port from accessing any system resources. When
this option is set to Disabled, the serial port physically becomes unavailable.
3F8/IRQ4
Set this value to allow the serial port to use 3F8 as its I/O port address and IRQ 4 for the
interrupt address. This is the default setting. The majority of serial port 1 or COM1 ports
on computer systems use IRQ4 and I/O Port 3F8 as the standard setting. The most
common serial device connected to this port is a mouse. If the system will not use a
serial device, it is best to set this port to Disabled.
2F8/IRQ3
Set this value to allow the serial port to use 2F8 as its I/O port address and IRQ 3 for the
interrupt address. If the system will not use a serial device, it is best to set this port to
Disabled.
3E8/IRQ4
Set this value to allow the serial port to use 3E8 as its I/O port address and IRQ 4 for the
interrupt address. If the system will not use a serial device, it is best to set this port to
Disabled.
2E8/IRQ3
Set this value to allow the serial port to use 2E8 as its I/O port address and IRQ 3 for the
interrupt address. If the system will not use a serial device, it is best to set this port to
Disabled.
