AP440FX The AP440FX motherboard is a 64-bit, high-performance, mixed-voltage, energy-conscious, highly integrated platform. The AP440FX motherboard supports the following set of features:

  • Uses a 9-inch by 13-inch LPX form factor.
  • Uses a type 8 Zero Insertion Force (ZIF) socket to house the standard processor, and provides an upgrade path to future Pentium® Pro OverDrive® processors.
  • Accepts Pentium Pro processors with core clock frequencies of 150 MHz, 180 MHz, and 200 MHz.
  • Supports up to 128 MB of DRAM using four standard 72-pin, tin-lead SIMM sockets. The modules can use Fast Page Mode (FPM) or Extended Data Out (EDO) memory. Non-parity (32-bit) and parity (36-bit) memory SIMMs are supported. With parity SIMMs, the board can be configured to support Error Checking and Correcting (ECC) memory operation.
  • Uses Intel's 82440FX chipset. The Intel 82371SB PCI/ISA IDE Xccelerator (PIIX3) provides an integrated Bus Mastering IDE controller with two high performance IDE interfaces for up to four devices (such as hard drives or CD-ROM).
  • Uses a Flash BIOS with the following features:
    • Uses both hardware and software Secure Flash features to protect Flash contents from corruption.
    • Uses a BIOS that complies with the Desktop Management Interface (DMI-compliant).
  • Uses the National Super I/O controller (the National PC87307 or the pin-compatible National PC87308 device) to integrate the following standard PC I/O functions:
    • floppy interface, two FIFO serial ports and one EPP/ECP capable parallel port,
    • Real Time Clock,
    • keyboard controller, and
    • support for an IrDA and Consumer Infrared interface at both slow and medium speeds.
  • Integrates a Crystal audio codec (CS4232 or the pin-compatible CS4236) on the motherboard to provide 16-bit stereo, Sound Blaster* Pro compatible audio. Provides an onboard telephony (modem) connector to support the latest telephony applications.
  • Integrates an S3* V+ or S3ViRGE graphics controller onboard to support SVGA graphics at resolutions up to 1600x1200 (when a full 2MB of video DRAM is installed). An enhanced LBP VESA feature connector supports external multimedia capabilities. (Standard configurations offer only the S3 ViRGE graphics controller)
  • A hardware monitoring ASIC provides the following monitoring functions:
    • Integrated temperature sensor
    • Fan speed monitoring
    • Power supply voltage monitoring
    • Storage of POST results and error codes
  • PCI and ISA expansion slots are supported by a connector on the motherboard designed to accept a riser card. An onboard jumper supports riser cards with either two or three PCI slots.
  • Two Universal Serial Bus connectors (on selected configurations)
