Parallel Port Address
This option specifies the I/O address used by the parallel port. The Optimal setting is
378 .
The Fail-Safe setting is Disabled .
Option Description
Disabled This option prevents the parallel port from accessing any system resources. It is not made
available.
378 This option allows the serial port to use 378 as its I/O port address. This is the default setting.
The majority of parallel ports on computer systems use IRQ7 and I/O Port 378H as the standard
setting.
278 This option allows the serial port to use 278 as its I/O port address.
3BC This option allows the serial port to use 3BC as its I/O port address.
Parallel Port Mode
This option specifies the parallel port mode. The Optimal setting is Normal . The Fail-
Safe setting is Disabled .
Option Description
Normal This option allows the standard parallel port mode to be used. This is the default setting.
Bi-Directional This option allows data to be sent to and received from the parallel port.
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 bi-directional
data transfer driven by the host device.
When EPP is selected, you can select the EPP Version as either 1.7 or 1.9.
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 bi-directional communication.
When ECP is selected, you can change the value of the ECP Mode DMA Channel. It can be set
to 0, 1, or 3.
Parallel Port IRQ
This option specifies the IRQ used by the parallel port. The Optimal and Fail-Safe
default setting is
7 .
Option Description
5 This option allows the serial port to use Interrupt 3.
7 This option allows the serial port to use Interrupt 7. This is the default setting. The majority of
parallel ports on computer systems use IRQ7 and I/O Port 378H as the standard setting.
