Onboard Parallel Port:
This item specifies the I/O address used by the parallel port.
[Disabled]:
This option prevents the parallel port from accessing any system
resources. When the value of this option is set to [Disabled], the printer port becomes
unavailable.
[378/IRQ7]:
This option allows the parallel port to use [378/IRQ7] as its I/O port
address. The majority of parallel ports on computer systems use IRQ7 and I/O Port
378H as the standard setting.
[278/IRQ5]:
This option allows the parallel port to use [278
/
IRQ5] as its I/O port
address.
[3BC/IRQ7]:
This option allows the parallel port to use [3BC
/
IRQ7] as its I/O port
address.
Parallel Port Mode:
This item specifies the parallel port mode.
[SPP]:
(Standard Parallel Port) Allows bi-directional parallel port operation at normal
speed.
[EPP]:
(Enhanced Parallel Port) Allows bi-directional parallel port operation at
maximum speed.
[ECP]
: (Extended Capabilities Port) Allows bi-directional parallel port operation at a
speed faster than the normal mode’s data transfer rate.
[ECP+EPP]:
Allows parallel port operation at ECP and EPP mode.
EPP Mode Select:
This item selects the EPP mode.
ECP Mode Use DMA:
This item selects the DMA channel of the parallel port.
