Onboard FDC Controller (Enabled)
This option enables the onboard floppy disk drive controller.
Onboard Serial Port 1/2 (3F8/IRQ4) (2F8/IRQ3)
This option is used to assign the I/O address and interrupt request (IRQ) for onboard
serial port 1 (COM1).
UART Mode Select (Normal)
This field is available if the Onboard Serial Port 2 field is set to any option but Disabled.
UART Mode Select enables you to select the infrared communication protocol-Normal
(default), IrDA, or ASKIR.
UR2 Duplex Mode (Half)
This field is available when UART Mode is set to either ASKIR or IrDA. This item
enables you to determine the infrared function of the onboard infrared chip. The options
are Full and Half (default). Full-duplex means that you can transmit and send informa-
tion simultaneously. Half-duplex is the transmission of data in both directions, but only
one direction at a time.
Onboard Parallel Port (378/IRQ7)
This option is used to assign the I/O address and interrupt request (IRQ) for the onboard
parallel port.
