Using BIOS
Onboard FDC Controller (Enabled)
Select Enabled if your system has a floppy disk controller (FDC) installed on the system
board and you wish to use it. If you install an add-in FDC or the system has no floppy drive,
select Disabled in this field.
Onboard Serial Port1 (3F8/IRQ4)
This option is used to assign the I/O address and interrupt request (IRQ) for onboard serial
port1 (COM1).
Press <Esc> to return to the Integrated Peripherals screen.
UART 2 Mode Control (Disabled)
This item allows users to enable or disable the onboard UART2 mode control.
UART 2 Select (Normal)
This field is available if the “Onboard Serial Port 2” 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.
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 you can transmit and receive data simultaneously.
Half-duplex is the transmission of data in either transmitting or receiving, only one direc-
tion at a time.
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.
Use IR Pins (IR-Rx2Tx2)
Please consult your IR peripheral documentation to select the correct setting of the
TxD and RxD signals.
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.
Onboard Parallel Port (378/IRQ7)
This option is used to assign the I/O address and interrupt request (IRQ) for the onboard
parallel port.
ECP Mode Use DMA (3)
When the onboard parallel port is set tp ECP mode, the parallel port can use DMA3 or
DMA1.
