mainboard.
Onboard FDD
This option enables the onboard floppy disk drive
controller.
Controller
Onboard Serial
This option is used to assign the I/O address for
the onboard serial port.
Port 1
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
This field is available when UART 2 Mode is set to
either ASKIR or HPSIR. This item determines the
Duplex
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
Defines the voltage level for Infrared module RxD
(receive) mode and TxD (transmit) mode. This
enable
setting has to match the requirements of the
infrared module used in the system.
Onboard Parallel
This option is used to assign the I/O address for
the onboard parallel port.
Port
Onboard Parallel
This feature enables you to set the data transfer
protocol for your parallel port. Normal allows data
Mode
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
When the onboard parallel port is set to ECP
mode, the parallel port has the option to use DMA
DMA
"3" or DMA "1."
Parallel Port EPP
This option sets the Enhanced Parallel Port (EPP)
specification.
Type
Onboard Legacy
This option enables the onboard legacy audio
function. When enabled the following items
