Setting Description
Normal
The normal parallel port mode is used.
Bi-Dir
Use this setting to support bidirectional transfers on 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 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 Version This option specifies the Enhanced Parallel Port specification version number that is
used in the system. This option only appears if the Parallel Port Mode option is set to
EPP.
The settings are 1.7 or 1.9. There are no Optimal and Fail-Safe default settings because
the default setting for the Parallel Port Mode option is not EPP.
Parallel Port DMA Channel This option is only available if the setting for the Parallel Port Mode
option is ECP. This option sets the DMA channel used by the parallel
port. The settings are (DMA Channel0, 1, or 3. The Optimal and Fail-
Safe default settings are not provided.
Parallel Port IRQ This option specifies the IRQ used by the parallel port. The settings are Auto,
(IRQ) 5, or (IRQ) 7. The Optimal and Fail-Safe default settings are Auto.
SAVE AND EXIT SETUP
Select this option when you finished setup the CMOS and it will save the change you made and reboot
the system after you press “YES”.
EXIT WITHOUT SAVING
If you decided not to save any change you had made, you can select this option to exit the CMOS setup
and all the change you made will be ignored.
