Onboard Parallel Port [378/IRQ7]

ECP Mode Use DMA 3
Onboard FDC Controller (Enabled)
This option enables the onboard floppy disk drive controller.
Onboard Serial Port 1/2 (3F8/IRQ4)(Disabled)
This option is used to assign the I/O address and interrupt request (IRQ) for onboard serial
port 1/2 (COM1/COM2).
• 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.
IrDA is an infrared communication protocol with a maximum baud rate up to
115.2K bps. ASKIR is Sharp’s infrared communication protocol with a maxi-
mum baud rate up to 57.6K bps.
• UR2 Duplex Mode (Half): This field is available when UART 2 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 information simultaneously.
Half-duplex is the transmission of data in both directions, but only one direc-
tion 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.
Parallel Port Mode (SPP)
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.
SPP allows data output only. Extended Capabilities Port (ECP) and Enhanced Parallel Port
(EPP) are bi-directional modes, allowing both data input and output. ECP and EPP modes
are only supported with EPP- and ECP-aware peripherals.
• 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.
