Parallel Port Mode :
This option specifies the parallel port mode. ECP and EPP are both bidirectional
data transfer schemes that adhere to the IEEE P1284 specifications. This
Parallel Port Mode includes four options “Normal”, “Bi-Dir”, “EPP”, and
“ECP”.
Setting Description
Normal Uni-direction operation at normal speed
Bi-Dir Bi-direction operation at normal speed
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 is only valid if the
Parallel Port Mode
option is set to
EPP
. This
option specifies the version of the Enhanced Parallel Port specification that will
be used by AMIBIOS.
◎
Parallel Port IRQ :
This option is only valid if the
Onboard Parallel Port
option is not set to
Disabled
. This option sets the IRQ used by the parallel port.
◎
Parallel Port DMA Channel :
This option is only available if
On Board Parallel Port
is set to fixed I/O
address and the setting of
Parallel Port Mode
is ECP. This option sets the
DMA channel used by ECP-capable parallel port.
On Board IDE
This option specifies the onboard IDE controller channels that will be used. The
settings are
Disabled
,
Primary
,
Secondary
, or
Both
.
