2-20 Setup and Operation
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, “EPP” for setting the parallel port to the
Enhanced Parallel Port, “Output Only,” and “Bi-directional” (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,” “278h,” and “3BC.”
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 1.” The
DMA field is only displayed when the Mode field is set to “ECP.”
Floppy Disk Controller
This field enables the diskette drive interface connector on the system board.
Choices include “Enabled” (the default) or “Disabled.”
IDE Controller
The IDE Controller field enables the IDE interface connectors on the riser board.
