Embedded Serial Port 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.
Disabled
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 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 do not use a
serial device, it is best to set this port to Disabled.
3F8/IRQ4
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.
2F8/IRQ3
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 do 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 2E8 as its I/O port address
and IRQ 3 for the interrupt address. If the system do not use a serial
device, it is best to set this port to Disabled.
