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 1/2 (COM1/2).
UART Mode Select (Normal)
• 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 transmit and send information simultaneously. Half-
duplex is the tranmission of data in both directions, but only one direction at a
time.
USB Emulation (ON)
• USB Keyboard Support (Enabled): Enabled this item if you plan to use a
keyboard connected through the USB port in a legacy operating system
(such as DOS) that does not support Plug and Play.
Onboard Parallel Port (378/IRQ7)
This option is used to assign the I/O address and interrupt request (IRQ) for the onboard
parallel port.
Parallel Port Mode (Normal)
Enables you to set the data transfer protocol for your parallel port. There are four options:
SPP (Standard Parallel Port), EPP (Enhanced Parallel Port), ECP (Extended Capabilities
Port) and ECP+EPP.
• ECP Mode Use DMA (3):When the onboard parallel port is set to ECP mode,
the parallel port can use DMA 3 or DMA 1.
