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.

NF7, NF7-S2G, NF7-M, NF7-S2, NF7-S specifications

The Abit NF7 series of motherboards, which includes the NF7-S, NF7-S2, NF7-M, NF7-S2G, and NF7, is renowned for its performance, stability, and advanced features tailored for AMD processors during the early 2000s. These boards were particularly popular for enthusiasts and gamers seeking to build high-performance systems with the nForce2 chipset, which significantly enhanced system capabilities.

The NF7-S, the flagship model, stood out due to its comprehensive feature set. It supported a broad range of AMD processors, including the Athlon XP and Duron, which made it an appealing choice for various users. One of its main attractions was the dual-channel memory technology, permitting up to 2GB of DDR RAM, effectively doubling memory bandwidth and improving performance in memory-intensive applications.

Another significant feature of the NF7-S was its integrated Universal Audio Codec, delivering high-quality sound without the need for a separate sound card. Additionally, it offered a fast 133MHz FSB (Front Side Bus), enabling remarkable speed in data transfer, thereby enhancing the overall system performance. The motherboard also featured several expansion slots, including AGP 8x and PCI slots, allowing users to install a range of graphics cards and peripherals.

The NF7-S2, a slightly reduced version, maintained many capabilities of the NF7-S while providing essential features suitable for budget-conscious builders. It came with single-channel memory support but still leveraged the strengths of the nForce2 chipset, ensuring solid performance for general computing and light gaming.

The NF7-M was tailored for micro-ATX systems, representing a compact solution for those who needed a smaller footprint without sacrificing performance. With similar specs to its larger counterparts, it also supported dual-channel memory and offered significant connectivity options.

The NF7-S2G included integrated graphics capabilities, catering to users who preferred a more straightforward setup without dedicated graphics cards. This model offered a great balance for everyday computing tasks and casual gaming.

In summary, the Abit NF7-series motherboards were pivotal in advancing desktop performance during their time, providing users with robust options filled with innovative technologies and a variety of features designed for different needs, solidifying their legacy in the history of computer hardware.
