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.

pliant Infrared Module Connector in 3.8 External Connectors. Configuration
options: [Disabled] [Enabled]

able. Configuration options: [Disabled] [378H/IRQ7] [278H/IRQ5]

normal-speed operation but in one direction only; [EPP] allows bidirectional paral-
lel port operation; [ECP] allows the parallel port to operate in bidirectional DMA

tion options: [Normal] [EPP] [ECP] [ECP+EPP]
