Chapter 3: Step by Step Tutorial for Hardware Installation

Pre installed mandatory anti-static requirements

Anti static workbench and grounding wristband throughout the process. It is forbidden to touch CPU/memory gold fingers with bare hands, as static electricity will permanently burn components.

3.1 CPU installation

Unlock the mPGA47 slot lock rod and remove the protective cover; CPU Triangle Mark Alignment Slot Pin1

The CPU is placed flat without external pressure, and the locking rod makes a clicking sound

Apply thermal grease evenly to the CPU core, lock the original heat dissipation module, and connect the fan to the FAN socket; Without heat dissipation, it will overheat, shut down, and burn out

3.2 DDR Memory Installation

DIMM1+DIMM2 must be inserted in pairs with the same specifications, and the slot buckle will automatically lock; Single memory cannot boot up properly, supports 64MB~1GB single DDR266

3.3 IDE hard drive wiring

Distinguish between primary/secondary IDE channels, align the motherboard and hard drive pins with the red Pin1 ribbon cable, and mount up to two IDE devices (primary/secondary) per channel

3.4 Basic BIOS Operations

Press Del to enter the Phoenix Ward settings interface during power on self-test, where you can adjust the startup sequence, serial port mode, parallel port type, WDT switch, power management, and hardware monitoring threshold; Parameters are stored in the lithium battery RTC

3.5 Key points of operating system installation

BIOS prioritizes setting CD/floppy drive startup; Before installing the system, load the original chipset driver and identify all PCI/ISA hardware

Chapter 4: Device Driver Installation (Windows Full Process)

The drivers are stored uniformly on the accompanying ADLINK CD, divided into three categories: chipset, graphics card, and network card. They support Win98/ME/NT/2000/XP and have a fixed installation sequence:

Intel 845GV chipset INF driver: Low level bus recognition, close background program to run Setup, restart after installation

Integrated graphics card driver: separate installation packages for Win9X/NT/2000/XP, covering 2D acceleration and multi display output

Intel 82540EM Gigabit Network Card Driver: Automatically batch recognizes dual network ports, supports WOL and PXE functions

The CD comes with the source code for watchdog testing under DOS, which can be used for secondary development of industrial control programs

Chapter 5 Development Instructions for Watchdog Timer WDT

Hardware architecture: Integrated on board programmable logic devices, two-level countdown, IO port 02E/02F control

Work logic: The software periodically executes the "feed dog" refresh timer; Trigger hardware reset of the entire machine after timeout

Two timing modes: second level (1-255s), minute level (1-255min)

Fault tracing: After the system restarts, the registers can be read to determine whether the restart was triggered by a watchdog

Development Resources: The CD provides complete DOS sample C code, which can be ported to Windows industrial control programs
