AP440FX Motherboard Technical Product Specification

<CTRL> <ALT> <defined in Setup>: Power down and coffee-break key sequences take advantage of the SMM features of the Pentium Pro processor to greatly reduce the computer’s power consumption while maintaining the responsiveness necessary to service external interrupts.

<CTRL> <ALT> <defined in Setup>: Keyboard secure hot keys lock the keyboard until user specified password is given.

1.8.3Real-Time Clock, CMOS RAM and Battery

The integrated real-time clock is compatible with DS1287 and MC146818 components. It provides a time of day clock, a 100-year calendar with alarm features, and a century register. The real-time clock can be set in the Setup program. The real-time clock also supports 242-byte battery-backed CMOS RAM in two banks which is reserved for BIOS use. The CMOS RAM can be set to specific values or cleared to the default values using the Setup program. Also, the CMOS RAM values can be cleared to the defaults by using a configuration jumper on the motherboard.

An external coin-cell style battery provides power to the real-time clock and CMOS memory. The battery used is a long-life version that is socketed for easy replacement. When the computer is on, the life of the battery is extended by a trickle current from the power supply.

1.8.4Infrared Support

A 5-pin interface on the front panel I/O connector allows connection to a Hewlett PackardHSDL- 1000 compatible infrared (IrDA) transmitter/receiver. Once the module is connected to the front panel I/O header, Serial port 2 can be redirected to the IrDA module. When configured for IrDA, the user can transfer files to or from portable devices such as laptops, PDAs and printers using application software such as LapLink. The IrDA specification provides for data transfers at 115kbps from a distance of 1 meter. Support for Consumer Infrared (ASK-IR and DASK-IR options for SHARP-IR) is also included. Consumer infrared is supported at both slow and medium speeds.

1.8.5Parallel Port

A 25-pin D-Sub header is provided on the back panel for a multi-mode bi-directional parallel port. The parallel port operates in standard mode, Enhanced Parallel Port (EPP) version 1.7 mode, with BIOS and Driver support, and a high speed Extended Capabilities Port (ECP) compatible mode.

EPP Mode requires a driver provided by the peripheral manufacturer to operate correctly.

1.9 Graphics Subsystem

The AP440FX motherboard is available with a factory option of an S3 ViRGEor ViRGE/DX SVGA graphics controller. Both options are supported by 2 MB of 50 ns EDO SOJ DRAM soldered to the motherboard. The AP440FX motherboard also supports the S3 media channel, also known as the Local Peripheral Bus (LBP) or Scenic Highway.

AP440FX specifications

The Intel AP440FX is a pivotal motherboard that was released in the late 1990s, designed to support the Intel Pentium II and Pentium III processors. Known for its robust performance and versatile functionalities, the AP440FX became a popular choice among computer enthusiasts and system builders during its time.

One of the defining features of the Intel AP440FX is its support for the Intel 440FX chipset. This chipset provided improved system performance through its use of a 66 MHz front-side bus, which allowed for faster data transfer between the CPU and the memory. The motherboard was equipped with two DIMM slots capable of supporting a maximum of 512 MB of SDRAM, providing users with the flexibility to choose the amount of memory they required for their applications.

Another notable characteristic of the AP440FX motherboard is its integrated support for various peripheral interfaces. It comes equipped with multiple ISA and PCI slots, allowing users to expand their system capabilities through the addition of various cards. The presence of two USB ports, which were relatively new at the time of its release, gave users access to a wider range of peripherals and external devices.

The Intel AP440FX also features an integrated IDE controller, enabling connection for hard drives and optical drives without the need for additional controller cards. This integrated solution simplified storage management for users and contributed to the overall efficiency of the system. The motherboard also supported SCSI through optional daughter cards, catering to users who required high-speed data transfer and reliable disk storage solutions.

Moreover, the AP440FX was designed with future upgrades in mind. Its BIOS supported plug-and-play installations, allowing users to easily configure new hardware components without extensive troubleshooting. Additionally, the ATX form factor of the motherboard contributed to its compatibility with a wide range of cases and power supplies.

In terms of power management, the Intel AP440FX incorporated advanced features such as ACPI (Advanced Configuration and Power Interface), which allowed for better power efficiency and management of power states. This feature was particularly beneficial for users looking to reduce energy consumption and improve the overall longevity of their systems.

All in all, the Intel AP440FX represented a significant advancement in motherboard technology during its era. Its combination of robust performance, upgradeability, and support for new technologies made it a popular choice for users looking to build powerful and efficient computing systems.
