I/O Device Config.
UART2 Use Infrared [Disabled]
When enabled, this field activates the onboard infrared feature and sets the
second serial UART to support the infrared module connector on the moth-
erboard. If your system already has a second serial port connected to the
onboard COM2 connector, it will no longer work if you enable the infrared
feature. [Disabled] leaves the second serial port UART to support the COM2
serial port connector. See IrDA-Compliant Infrared Module Connector
in 3.8 External Connectors. Configuration options: [Disabled] [Enabled]
Onboard Parallel Port [378H/IRQ7]
This field sets the address of the onboard parallel port connector. If you
install an I/O card with a parallel port, ensure that there is no conflict in the
address assignments. The PC can support up to three parallel ports as long
as there are no conflicts for each port. Configuration options: [Disabled]
[3BCH/IRQ7] [378H/IRQ7] [278H/IRQ5]
Parallel Port Mode [ECP+EPP]
This field allows you to set the operation mode of the parallel port. The
setting [Normal], allows normal-speed operation but in one direction only;
[EPP] allows bidirectional parallel port operation at maximum speed; [ECP]
allows the parallel port to operate in bidirectional mode and at a speed
faster than the maximum unidirectional data transfer rate; [ECP+EPP] al-
lows normal speed operation in a two-way mode. Configuration options:
[Normal] [EPP] [ECP] [ECP+EPP]
ECP DMA Select [3]
This field allows you to configure the parallel port DMA channel for the
selected ECP mode. This selection is available only if you select [ECP]
or [ECP+EPP] in Parallel Port Mode above. Configuration options: [1]
[3] [Disabled]
