Serial Port1 Address
This option specifies the base I/O port address and Interrupt Request address of serial port 1.
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.
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.
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.
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.
Serial Port2 Address
This option specifies the base I/O port address and Interrupt Request address of Serial
Port2. The settings of Serial Port2 are the same as Serial Port1. However, the setting used
by Serial Port1 will not be available for Serial Port2. For example, if Serial Port1 uses 3F8/
IRQ4, the option, the 3F8/IRQ4 will not appear in the options of Serial Port2.
Parallel Port Address
This option lets to configure the SuperIO’s parallel port address.
Parallel Port Mode
This option specifies the parallel port mode.
Option Description
Normal Set this value to allow the standard parallel port mode to be used.
EPP The parallel port can be used with devices that adhere to the Enhanced Parallel Port (EPP)
specification. EPP uses the existing parallel port signals to provide asymmetric bidirectional data
transfer driven by the host device.
ECP
The parallel port can be used with devices that adhere to the Extended Capabilities Port (ECP)
specification. ECP uses the DMA protocol to achieve data transfer rates up to 2.5 Megabits per
second. ECP provides symmetric Bidirectional communication.
EPP+ECP Allows the parallel port to support both the ECP and EPP modes simultaneously.
