Parallel Port
Selectable parameters for this field are “Disabled,”
“Enabled” (default), and “Auto.” The parallel port
device can be auto detected by choosing “Auto.” When
“Auto” is selected, the first free LPT port is assigned.
Setting this field to “Auto” enables the device, but the
BIOS will not place its resources unless the “PnP OS”
field described previously is set to “No.”
Select “Enabled” if you want to choose a specific
address. The following options become available:

Mode
Choices include: “ECP” for setting the parallel port
to the Enhanced Capabilities Port (ECP) mode,
“Output Only,” and “Bidirectional” (sets the parallel
port to input/output mode only). The default setting
is “Bi-directional.”

Base I/O address
Available addresses include “378h” (the default),
“228h,” and “278h.”

Interrupt
Available IRQs include “IRQ7” (the default) and
“IRQ5.”
NOTE
An interrupt set to IRQ5 in a multimedia
system might conflict with the audio subsystem
settings.

DMA Channel
Available DMA settings include “DMA 3” (the
default), and “DMA 5.” The DMA field is not
displayed when the Mode field is set to
“Bi-directional.”
