Abit NF7-S2G EXT-P2P’s Discard Time, Onboard FDD Controller, Onboard Serial Port, Use IR Pins

BIOS Setup 3-19

EXT-P2P’s Discard Time:

This item allows you to set EXT-P2P’s discard time.

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.
