Parallel Port Address
This field selects the I/O address used to access the parallel interface.
The possible values are: Disabled,
378
, 278, 3BC.
The use of address space 3BC may be restricted for some modes because it doesn’t allow for
eight consecutive addresses.
10.3.4.4.
Parallel Port Mode
This field is used to specify whether the parallel port is to be used as a bi-directional input/output port or just as an output
port. ECP and EPP transfer modes allow faster transfer rates of 2 and 2.4 Mbytes/s. These modes will only work with
peripheral devices which support them. In addition, the field Parallel Port Address must be set to 378 or 278 when using
one of these two modes.
Normal
The port functions as an output port only.
Bi
-Directional
Data can be transferred in both directions across the port.
EPP
Fast transfer mode (up to 2 Mbytes/s), can output and receive data. The mode requires a peripheral
device which supports the EPP (Enhanced Parallel Port) transfer mode.
ECP
Fast transfer mode (up to 2.4 Mbytes/s), can output and receive data. The mode requires a
peripheral device which supports the ECP (Enhanced Capability Port) transfer mode.
ECP & EPP
Fast transfer mode (up to 2.4 Mbytes/s), can output and receive data. The mode requires a
peripheral device which supports both EPP (Enhanced Parallel Port) and ECP (Enhanced Capability
Port) transfer mode.
10.3.4.5.
Parallel Port IRQ
This field selects the interrupt used for the parallel interface.
It is possible to choose between:
IRQ7
and IRQ5.
IRQ7
This setting allows the parallel port to use the interrupt IRQ7.
IRQ5
This setting allows the parallel port to use the interrupt IRQ5.
