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. The default
setting is
Normal
. The other settings are:
Setting
Description
Normal
Normal The normal parallel port mode is used. This is the default setting.
Cache
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 transfer rates of approximately 2.5 Mbs. ECP provides symmetric
Bidirectional communications.
Parallel Port IRQ:
This option specifies the IRQ used by the parallel port. The Optimal and
Fail-Safe default setting is 7.
Option
Description
5
This option allows the serial port to use Interrupt 3.
7
This option allows the serial port to use Interrupt 7. This is the default setting.
The majority of parallel ports on computer systems use IRQ7 and I/O Port
378H as the standard setting.
Parallel Port DMA Channel:
This option is only available if the setting for the
Parallel Port
Mode
option is ECP. The settings are Disabled, DMA CH (channel) 0, DMA CH 1, or DMA CH
3. The default setting is N/A.
On-Chip IDE:
This allows you to enable or disable on-chip IDE controller. Settings are Disabled,
Primary, Secondary and Both.
