Configure Super IO ChipSet
You can use this screen to select options for the Super I/O
settings. Use the up and down <Arrow> keys to select an
item. Use the <Plus> and <Minus> keys to change the
value of the selected option. The settings are described
on the following pages. The screen is shown at right.
Serial Port1 Address
This option specifies the base I/O port address and Interrupt
Request address of serial port 1. The Optimal setting is
3F8/IRQ4. The Fail-Safe default setting is Disabled.
Option
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.
