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)
