IR Function Duplex (Half)
This field is available when UART 2 Mode is set to either ASKIR or
HPSIR. This item enables you to determine the infrared (IR) 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.
TX,RX inverting enable (No, Yes)
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 (378/IRQ7)
This option is used to assign the I/O address for the onboard
parallel port.
Onboard Parallel Port Mode (ECP)
Enables you to set the data transfer protocol for your parallel
port. There are four options: Normal (Standard Parallel Port),
EPP (Enhanced Parallel Port), ECP (Extended Capabilities
Port) and ECP+EPP.
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 periph-
erals.
ECP Mode Use DMA (3)
When the onboard parallel port is set to ECP mode, the paral-
lel port has the option to use DMA 3 (default) or DMA 1.
Parallel Port EPP Type (EPP1.7)
Sets the EPP specification. There are two options, EPP1.9
and EPP1.7.
If you make any changes to the onboard FDD controller, serial
ports or parallel ports in this setup, save the changes and turn
off the system. After powering up the system, ensure that the
changes have taken effect.
