Onboard FDC Controller (Enabled)
This option enables the onboard floppy disk drive controller.
Onboard Serial Port 1 (3F8/IRQ4)
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 communica-
tion 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 maximum baud rate up to
57.6K bps.
•
UR2 Duplex Mode (Half):
Mode is set to either ASKIR or IrDA. This item enables you to de-
termine the infrared (IR) function of the onboard infrared chip. The
options are Full and Half (default).
Full-duplex means that you can transmit and send information si-
multaneously. 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.
Parallel Port Mode (ECP)
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.
When EPP mode is selected the following item becomes available:
•
EPP Mode Select:
PWRON After PWR-Fail (Off)
This item enables your computer to automatically restart or return to its last
operating status after power returns from a power failure.
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.
Game Port Address (201)
This item sets the I/O address for the game port.
Midi Port Address (330)
This item sets the I/O address for the Midi function.
This field is available when UART 2
Enables you to set the EPP port type, 1.7 or 1.9.
