Onboard Serial Port 1 (3F8/IRQ4)
This option is used to assign the I/O address and interrupt request (IRQ)
for onboard serial port 1 (COM1).
Onboard Serial Port 2 (2F8/IRQ3)
This option is used to assign the I/O address and interrupt request (IRQ)
for onboard serial port 2 (COM2).
UART Mode Select (Normal)
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-Normal (default), IrDA, or ASKIR. IrDA is an
infrared communication protocol with a maximum baud rate up to 115.2K
bps. ASKIR is Sharp's infrared communication protocol with a maximum
baud rate up to 57.6K bps.
•
RxD, TxD Active (Hi, Lo): This feature enables you to set the
IR reception/transmission polarity as High or Low.
•
IR Transmission Delay (Enabled): This field enables you to
set the whether the IR transmission rate will be delayed while
converting to receiving mode.
•
UR2 Duplex Mode (Half): This field is available when UART
2 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 (default).
Full-duplex means that you can transmit and send information
simultaneously. Half-duplex is the transmission of data in both
directions, but only one direction at a time.
•
Use IR Pins (IR-Rx2Tx2): Please consult your IR peripheral
documentation to select the correct setting of the TxD and
RxD signals.
Onboard Parallel Port (378/IRQ7)
This option is used to assign the I/O address and interrupt request (IRQ)
for the onboard parallel port.
Parallel Port Mode (ECP)
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.
ECP Mode Use DMA (3)
When the onboard parallel port is set to ECP mode, the parallel port can
use DMA 3 or DMA 1.
Power On After Power Fail (Off)
This item enables your computer to automatically restart or return to its
last operating status after power returns from a power failure.
