1 Motherboard Description

1.1 Overview

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 OverDrive®processors.

∙Accepts Pentium®Pro processors with core clock frequencies of 150 MHz, 166 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 Semiconductor Super I/O controller (the PC87307 or the pin-compatible 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

⎯support for an IrDA† and Consumer Infrared interface at both slow and medium speeds

∙Integrates a Crystal audio codec (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† ViRGE/DX† graphics controller onboard to support SVGA graphics at resolutions up to 1600x1200. An enhanced LBP VESA† feature connector supports external multimedia capabilities.

∙A hardware monitoring ASIC provides the following monitoring functions:

⎯Integrated temperature sensor

⎯Fan speed monitoring

⎯Power supply voltage monitoring

⎯Storage of power-on self test (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.
