IrDA Protocol The settings are 1.6 us or 3/16. The Optimal and Fail-Safe default settings are
1.6 us.
Onboard Parallel Port This option specifies the base I/O port address of the parallel port on the
motherboard. The settings are Auto, Disabled, 378, 278, or 3BC. The Optimal
and Fail-Safe default settings are Auto.

default settings are ECP. The settings are:
Setting
Normal
The normal parallel port mode is 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.
Bi-Dir
Data can be sent to and received from the parallel port.
EPP Version
This option specifies the Enhanced Parallel Port specification version number
that is used in the system. This option appears only if the Parallel Port Mode
option is set to EPP. The settings are 1.7, 1.9, and N/A.
There are no Optimal and Fail-Safe default settings because the default setting
for the Parallel Port Mode option is not EPP. If the Parallel Port Mode is set
to Normal or ECP, then N/A displays.
