4. BIOS SETUP

 I/O Device Config

When enabled, this field activates the onboard standard infrared feature and
sets the second serial UART to support the infrared module connector on
the motherboard. 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. See IrDA-Compliant Infrared Module Connector in 3.8
External Connectors. Configuration options: [Disabled] [Enabled]

This field sets the address of the onboard parallel port connector.  If you
disable this feature, Parallel Port Mode and ECP DMA Select configura-
tions will not be available. Configuration options: [Disabled] [378H/IRQ7]
[278H/IRQ5]

This field allows you to set the operation mode of the parallel port. [Nor-
mal] allows normal-speed operation but in one direction only; [EPP] allows
bidirectional parallel port operation; [ECP] allows the parallel port to oper-
ate in bidirectional DMA mode; [ECP+EPP] allows normal speed operation
in a two-way mode. Configuration options: [Normal] [EPP] [ECP]
[ECP+EPP]

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. Configuration options: [1] [3] [Dis-
abled]

This field sets the address of the onboard Consumer IR connector. Configu-
ration options: [Disabled] [2E0-2E8H] [3E0-3E8H]
