4. BIOS SETUP Onboard IR [Disabled] This field allows you to activate the onboard standard infrared feature and to set the address for 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: [3F8H/IRQ4] [2F8H/IRQ3] [3E8H/IRQ4] [2E8H/IRQ10] [Disabled] Onboard Parallel Port [378H/IRQ7] This field sets the address of the onboard parallel port connector.
If you disable this feature, Parallel Port Mode and ECP DMA Select configurations will not be avail- able. 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. [Normal] allows normal-speed operation but in one direction only; [EPP] allows bidirectional parallel port operation; [ECP] allows the parallel port to operate in bidirectional DMA mode; [ECP+EPP] allows normal speed operation in a two-way mode. Configuration op- tions: [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] I/O Device Config 4. BIOS SETUP ASUS CUA User’s Manual 64
