UART2 Mode Select
This item allows you to determine which InfraRed(IR) function of the onboard I/O chip, this
functions uses.
IrDA Duplex Mode
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 information simultaneously.
Half-duplex is the transmission of data in both directions , but only one direction at a time.
Onboard Parallel Port
There is a built-in parallel port on the on-board Super I/O chipset that Provides Standard, ECP,
and EPP features. It has the following option:
Disabled
(3BCH/IRQ7)/
Line Printer port 0
(278H/IRQ5)/
Line Printer port 2
(378H/IRQ7)
Line Printer port 1
Parallel Port Mode
SPP : Standard Parallel Port
EPP : Enhanced Parallel Port
ECP : Enhanced Com Port
SPP/EPP/ECP/ECP+EPP
To operate the onboard parallel port as Standard Parallel Port only, choose “SPP.” To operate
the onboard parallel port in the EPP modes simultaneously, choose “EPP.” By choosing “ECP”,
the onboard parallel port will operate in ECP mode only. Choosing “ECP+EPP” will allow the
onboard parallel port to support both the ECP and EPP modes simultaneously. The ECP mode
has to use the DMA channel, so choose the onboard parallel port with the ECP feature. After
selecting it, the following message will appear: “ECP Mode Use DMA” at this time, the user can
choose between DMA channels 3 to 1. The onboard parallel port is EPP Spec. compliant, so
after the user chooses the onboard parallel port with the EPP function, the following message will
be displayed on the screen: “EPP Mode Select.” At this time either EPP 1.7 spec. or EPP 1.9
spec. can be chosen.
