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
•
Accepts Pentium
180 MHz, and 200 MHz.
•
Supports up to 128 MB of DRAM using four standard 72-pin, tin-lead SIMM
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
•
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
resolutions up to 1600x1200. An enhanced LBP VESA
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.
