Mainboard User’s Manual
Init Display First
Use this item to define if your graphics adapter is
installed in one of the PCI slots or select Onboard
if you have a graphics system integrated on the
mainboard.
Onboard FDD
Controller
This option enables the onboard floppy disk drive
controller.
Onboard Serial
Port 1
This option is used to assign the I/O address for
the onboard serial port.
Onboard IR Port
This option is used to assign the I/O address for
the onboard IR port or disabled.
UART2 Mode
This field is available if the Onboard Serial Port 2
field is set to any option but “Disabled.” UART
Mode enables you to select the infrared
communication protocol—Standard (default),
HPSIR or ASKIR. HPSIR is Hewlett Packard’s
infrared communication protocol with a maximum
baud rate up to 115.2 Kbps. ASKIR is Sharp’s
infrared communication protocol with a maximum
baud rate up to 57.6 Kbps.
IR Function
Duplex
This field is available when UART 2 Mode is set to
either ASKIR or HPSIR. This item determines the
infrared (IR) function of the onboard infrared chip.
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.
TX, RX inverting
enable
Defines the voltage level for Infrared module RxD
(receive) mode and TxD (transmit) mode. This
setting has to match the requirements of the
infrared module used in the system.
Onboard Parallel
Port
This option is used to assign the I/O address for
the onboard parallel port.
Onboard Parallel
Mode
This feature enables you to set the data transfer
protocol for your parallel port. Normal 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
When the onboard parallel port is set to ECP
mode, the parallel port has the option to use DMA
“3” or DMA “1.”
Parallel Port EPP
Type
This option sets the Enhanced Parallel Port (EPP)
specification.
