ADLINK NuPRO-775 Industrial Motherboard Installation and BIOS Configuration Detailed Explanation

Enter extended function mode: Write 87h twice to the 2Eh port.

Select logical device 8 (write 08h through configuration register 07h).

Set CRF7 (configuration register F7h) to C0h to enable watchdog.

Set the bit3 selection unit for CRF5 (F5h) (0=seconds, 1=minutes).

Set the countdown value for writing CRF6 (F6h) (e.g. 0Fh=15).

Exit extended function mode: Write AAh to 2Eh.

The watchdog can be reloaded via keyboard or mouse interrupt. ADLINK provides subroutines for DOS/Windows, which can be obtained from the CD. In practical applications, the upper computer program needs to periodically "feed the dog", otherwise the system will reset, which is suitable for preventing system crashes in unmanned devices.

Installation of onboard VGA driver

The Intel i82810 integrated graphics controller requires the installation of dedicated drivers to leverage its AGP 2X and 3D acceleration capabilities. The manual explains two situations: Windows 98/95 and Windows NT 4.0.

1. Windows 98/95 installation steps

Extract the driver files from the CD to a temporary directory, which will automatically generate a "Graphics" subdirectories.

Run SETUP.EXE and continue after agreeing to the license agreement.

Follow the on-screen prompts to complete the installation and restart the system.

After restarting, Windows will automatically recognize the new hardware and load the driver. If the "New Hardware Found" dialog box pops up, you can manually specify the driver path.

2. Windows NT 4.0 Installation Instructions

Important prerequisite: Windows NT 4.0 Service Pack 4 (version 4.00.1381) must be installed before installing the VGA driver, otherwise it may not display properly. The driver installation process is similar to 98, run SETUP.EXE and restart.

Intel 82559 LAN Driver and Diagnosis

The onboard Ethernet controller supports 10/100Mbps adaptation, and the driver supports multiple protocols such as NetWare, SQLite, Packet, etc. The CD provides diagnostic tools, which can be accessed by executing D: NUPRO NuPRO775 LAN 82559 etup.exe in DOS to enter the menu:

View adapter configuration: View adapter resources, MAC addresses, etc.

Test adapter: Perform hardware loop testing to verify the functionality of the network chip.

Install network drivers: Select the corresponding network operating system for installation.

View Help files: View help documents.

Diagnostic tools are very practical for troubleshooting issues such as network disconnections and interruption conflicts.

Hardware Doctor, a hardware monitoring tool

Winbond W83627HF has built-in hardware monitoring, which, when combined with the Hardware Doctor tool on the CD (supports both English and Chinese), can monitor in real-time on Windows 95/98/NT:

System voltage (Vcore,+2.5V,+3.3V,+5V,+12V, -12V, VBAT,+5VSB)

CPU and system temperature (onboard sensor+CN11 external sensor)

CPU fan speed (requires 3-wire fan)

Users can customize the upper and lower limits of each parameter. When the range is exceeded, a warning box will pop up and a buzzer alarm can be selected. Specifically, the Case Open detection function can trigger an alarm when the case cover is opened, requiring a password to be entered to unlock and increase anti intrusion security.

Attention: If the fan is not connected, the software will display "Low speed". At this time, it is necessary to disable the fan monitoring in the configuration page to avoid false alarms.

Common troubleshooting and suggestions

Based on the manual and on-site experience, summarize several typical problems and countermeasures:

The system cannot start, black screen: check if the CPU is installed correctly and if the heat sink is in good contact; Check if the memory module is securely plugged in and try replacing the slot (only one slot, memory compatibility needs to be confirmed); Clear CMOS (short-circuit jumper or remove battery).

IDE hard drive not recognized or UDMA error: Check if the IDE cable has 80 cores (supports DMA/66), and try to set UDMA to Disabled and downgrade to PIO mode in BIOS.

Abnormal display or low resolution of onboard VGA: Confirm that the driver is installed correctly and check if the On Chip Video Window Size is set to 64MB in the BIOS.

Network connection failure: Run LAN diagnostic tool and check the link status lights (LED1's A light indicates 10/100M, B light indicates Link/Activity). If the driver installation still does not work, check if Wake On LAN is enabled in the BIOS (but this feature does not directly affect communication).

Watchdog unexpected reset: Check if the application regularly writes overload values to the watchdog register, or confirm that the watchdog timeout unit (seconds/minute) is set correctly.

Shutdown due to high temperature: Check if the CPU fan is stopped, clean the dust from the heat sink, and adjust the Shutdown Temperature appropriately in the BIOS (but not exceeding the upper limit of the CPU specifications).
