Onboard FDD Controller:
Two options are available: Enabled and Disabled. The default setting is Enabled. You can enable or
disable the onboard FDD controller.
Onboard Serial Port 1:
This is used to specify the I/O address and IRQ of Serial Port 1. Six options are available: Disabled
3F8/IRQ4 2F8/IRQ3 3E8/IRQ4 2E8/IRQ3 AUTO. The default setting is 3F8/IRQ4.
Onboard Serial Port 2:
This is used to specify the I/O address and IRQ of Serial Port 2. Six options are available: Disabled
3F8/IRQ4 2F8/IRQ3 3E8/IRQ4 2E8/IRQ3 AUTO. The default setting is 2F8/IRQ3.
If you choose Disabled, the following items will not be available to set.
Onboard IR Function:
Three options are available: IrDA (HPSIR) ASKIR (Amplitude Shift Keyed IR) Disabled. The
default setting is Disabled.
When you select the item IrDA or ASKIR, the following items will be available to set.
RxD , TxD Active:
Four options are available: Hi, Hi Hi, Lo Lo, Hi Lo, Lo. The default setting is Hi, Lo. Set IR
transmission/reception polarity as High or Low.
IR Transmission Delay:
Two options are available: Enabled and Disabled. The default setting is Enabled. Set IR transmission
delays 4 character-time (40 bit-time) when SIR is changed from RX mode to TX mode.
IR Function Duplex:
Two options are available: Full and Half. The default setting is Half. Select the value required by the IR
device connected to the IR port. Full-duplex mode permits simultaneous two-direction transmission.
Half-duplex mode permits transmission in only one direction at a time.
Use IR Pins:
Two options are available: RxD2, TxD2 and IR-Header. The default setting is IR-Header. If you choose
RxD2, TxD2, your motherboard must support a COM port IR KIT connection. Otherwise, you can only
choose the IR-Header to use the IR header on your motherboard to connect your IR KIT. Please use the
default setting.
NOTE: The setting for item “RxD, TxD Active”, also called “TX, RX inverting”, allows you to
determine the activity of RxD and TxD. We set it to “Hi, Lo”. If your motherboard BIOS uses “No” and
“Yes” to represent this item, you should set it to the same setting as the NF7/NF7-M/NF7-S. This means
that you should set it to “No, Yes” in order to match the transfer and receiving speed. If you fail to do so,
you will not get an IR connection between the NF7/NF7-M/NF7-S and the other computer.
