Description
This option enables the onboard floppy disk
drive controller.
This option is used to assign the I/O address
and interrupt request(IRQ) for onboard serial
port 1.
This field is available if the onboard serial port 2
field is set to any option but Disabled. UART
Mode Select enables you to select the infrared
communication protocol-IrDA, ASKIR or SCR
This field is available when UART mode is set
to either ASKIR or IrDA. This item enables you
to determine the infrared function of the
onboard infrared chip. The options are Full and
Half. Full-duplex means that you can transmit
and send information simultaneously. Had-
duplex is the transmission of data in both
directions, but only one direction at a time.
This option is used to assign the I?O address
and interrupt request(IRQ) for the onboard
parallel port.
Enables you to set the data transfer protocol for
your parallel port. There are four options:
SPP(Standard Parallel Port), EPP(Enhanced
Parallel Port), ECP(Extended Capabilities Port)
and ECP+EPP
SPP allows data output only. Extended
Capabilities Port(ECP) and Enhanced Parallel
Port(EPP) are bi-directional modes, allowing
both data input and output. ECP and EPP
modes are only supported with EPP- and ECP-
aware peripherals.
When the onboard parallel port is set to ECP
mode, the parallel port can use DMA 3 or DMA
