Chapter 2 Getting Started

Requirements for unpacking and anti-static measures: Use anti-static wristbands/bags throughout the process. Do not touch the chip with bare gold fingers. If damaged, contact the dealer immediately for replacement;

System deployment method: It can be used as the main control slot of cPCI chassis system or run independently as a regular peripheral slot, and the backplane needs to lead out the J1/J2 standard cPCI bus;

Hard requirements for heat dissipation: The factory comes with a CPU heat sink, which must run continuously at 1m/s through the chassis air duct; Without forced air cooling, the CPU may overheat and be permanently damaged;

BIOS basic operations: Press Del to enter Award plug and play BIOS upon startup, supporting serial port remote console redirection, PXE boot, and ACPI/APM energy-saving;

Operating system installation steps: Prioritize configuring peripherals → Set BIOS boot sequence → Deploy Windows 98/2000/NT/Linux via floppy disk/CD.

Chapter 3 Hardware Configuration (Jumpers, Resistors, Buttons)

Front switch

Dismantle R28/R29, weld R30/R31: PMC slot 3.3V power supply.

Chapter 4 Special Instructions for Watchdog Timer

Two level protection logic: software fails to feed the dog on time → first level triggers NMI unshielded interrupt; Continuous no feeding to the dog → Second level machine hardware reset;

Register operation port 3F0h, both read and write can reset the timer counter; BIOS/application can read reset flags and distinguish whether a watchdog triggers a restart;

The CD comes with a complete DOS C language sample program, which can be directly integrated with industrial control upper computer and lower computer programs to achieve automatic recovery from system crashes.

All drivers are stored on the accompanying integrated CD, divided into five major directories: chipset, graphics card, network card, watchdog, and hardware monitoring. They support systems such as Windows 98/2000/NT, Linux, Netware, QNX, etc. The installation points for each system are as follows:

440BX chipset driver: Bottom layer bus, PCI bridge basic driver, priority installation;

ATI M6-M graphics card driver: NT systems require the installation of SP6 or higher patch packages to enable AGP acceleration;

82559 Network Card Driver: NT systems require pre made driver floppy disks, which can be manually updated by the Device Manager;
